Moreover, in the present embodiment, the operation procedure can be saved by making the rotation directions of the small rotary tool F and the large rotary work p ^ , ^ G uniform. The first pre-borrowing τ 4 of this embodiment. The sequence of friction stir in the life reserve and the spare part of the beaker is described in detail in Figures 6 and 7. First, as shown in Fig. 6a, the small rotary tool F is located directly above the start position Sn of ν which is disposed at the appropriate position of the first projecting member 2, and then, the small rotary tool F is rotated rightward. When the side of the τ is lowered, the stirring pin F 2 is pushed to the starting position Sp!. For small-sized rotary workers, the ρ and 疋 rotation speeds are set corresponding to the material and thickness of the metal member 1 to be joined by friction, and most of the conditions are 2036-9981-PF; the Chentf 22 condition is set. to. , ~20 00 (rpm) range. When the field-receiving pin F2 contacts the surface 22 of the first projecting material 2, the metal around the pinning pin p2 is plastically fluidized, and as shown in Fig. 6b, the stirring pin (2) is inserted into the first projecting material 2. After the entire length of the stirring pin F2 enters the first protruding material 2 and the entire surface of the lower end surface of the shoulder portion F1 contacts the surface 22 of the first protruding material 2, as shown in FIG. 7 , the rotating tool F is rotated toward the side. The first protruding material is joined to the starting point S2 of the smuggling work for relative movement. The movement speed (rotation speed) of the small rotary tool F is set in accordance with the size and shape of the stirring blade 2, the material and thickness of the joined metal member 1 such as the film-scraping, and the like. In most cases, Set within the range of 1 00 to minutes). The rotation speed of the small rotary tool .F is the same as or lower than the rotation speed at the time of insertion. Further, when the small rotary tool F is moved, the axis of the shoulder portion F1 can be slightly inclined toward the rear side in the traveling direction with respect to the lead straight line, but the direction of the +-type rotary tool F can be easily changed without tilting. Do complicated exercises. When the small-sized rotary tool F moves, the metal around the mixing pin is plastically fluidized at the same time, and the metal after the plastic fluidization is hardened again at the position separated from the (four) pin F2. After the small rotary tool F is relatively moved and continuously thrown to the starting point s2 of the first-projection jointing work, 'the starting point is such that the small rotary tool F does not disengage and moves to the first protruding material to receive the artificial spear. . (2-1) The first projecting joint project in the first-projection material joining project, for the u (four) 2036-9981-PF; the joint metal member of the Chent 23 5 metal member 舆] . Specifically, 'the path of the rubbing and stirring, the setting of the joints (the boundary line) of the child's large output 2, and the setting of the friction part, the grinding and the small rotating tool F are relatively moved, 1 JZ enters the friction and surnames ^ Small rotating tool F in the middle, mix. In the present embodiment, in the present embodiment, the t-way is not deviated from the starting point S2, and the % of the brother-in-law jointing work is continuously performed, and the stalk is mixed to the end point e2. Moreover, in the case where the small rotary tool is made into a small rotary tool: F is right-turned, the result is "#I". On the left side, there is a position where the fine hole defect f ^ ^ is the starting point β and the end point e2 of the workpiece, so that the right side of the joined metal member 1 is on the side of the traveling direction of the small rotary tool F. Thus, it is difficult to produce a void in the component 1 side due to the difficulty in the absence of the tortoise. Similarly, in the case where the small rotary machine is obtained, and the left and right F are obtained, there is a small void in the right side of the direction due to the small rotating tool F. The position of the first projection, the starting point §2 of the material joining process, and the position of the end point are set such that the joined metal member 1 is positioned on the left side in the traveling direction of the small rotary tool F. Specifically, the starting point position s2 in the case where the small rotary tool F is rotated right is set, and the starting point position s2 can be set at the position of the end position ^ when the small rotary tool F is rotated right. The location sets the end point. Further, when the mixing pin F2 of the small rotary tool F enters the protruding portion 0, the metal member is pulled by the force of the first protruding member 2, and the metal member is joined by the welding! The inner corner portions 2a and 2b (see FIG. 3) formed by the first protruding material 2 are false-joined, and thus joined 2036-998l-PF; the Chentf 24 丄妁9055 metal member 1 and the first protruding member 2 There will be no openings between them. (2-2) The false jointing work/after the rotary tool F reaches the end point β of the first projecting joint project, the friction stir is not finished at the end point e2, and the friction stir is continuously performed ^= the starting point sl of the joining project, In this state, it moves to the false joint project. That is, the younger brother: the end point e2 of the projecting joint project to the starting point S1 of the false jointing work, the ii rotating tool F is not detached, and the squeezing of the squeezing tool F is continued, and the small rotating #F is not detached and moves to the false joint project. . As a result, the small rotary tool at the end point e2 of the first projecting joint project: the work is unnecessary, and the preliminary joining work can be performed efficiently and quickly. In the present embodiment, the end point of the first-protrusion # joining project is repeated. The starting point of the project si friction stirring path is set to the first protruding material 2, and the tool F is moved from the end point e2 of the first protruding material joining project, from the end of the first protruding material joining project... In the engineering of έ Sl, it is difficult to obtain a high-quality bonded body due to the occurrence of void defects in the joined metal members. The person stands in the direction of the surface of the workpiece. Part J1 (refer to Fig. 7) is subjected to friction stir. And the path of the secret mixing is set to be bent, and the limbs are s, and the friction is stirred on the joint (boundary line) of the 5 metal members 1, by making the small rotating tool F along π, Move, and cross the surface side...the length of the η is continuously and frictionally searched. In the form, the small rotary worker IF is detached from the fake joint project 2036-998l-PF; the starting point S1 of the Chentf 1^59055 to the end point el k in the present package /, F does not detach from the figure. Friction stir. After the small material is combined with the end point, the friction stir is not 鈇, after -e, at the starting point of the material joining project, the friction is given to the second point wr. The path is over the point s 3, and the station must be eight times. . In other words, from the false manual 襄, '" to the second protruding material bonding machine, so that the small rotating work; 1 brother two protruding material joints and: mixing, and in the second: no detachment and continuous The friction is found at the starting point S3 to make the small rotating two protruding material joint project.

Further, when the small boring tool is engaged with the metal member i and the "pin F2 into the protruding portion" 3, the ceremonial (refer to Fig. 3) is spliced by the inner corner portion 3a of the protruding member 3, and the first protruding portion The opening of the yoke y false joint 'the jointed metal member 1 盥 brother-dog output 3 does not create an opening. -

After the small rotary tool F, the end point e3 d at the end of the large-scale joint project does not end the friction. The last name, two, * to 5, and the end position of the 4th protrusion 3 and the mixing, will end. The position EPI is set to appear on the surface of the joint of the joint (the boundary line) of the present embodiment A. That is, the end position Ep! is silk, ten·

In the back side of the joint work, the grip is found for the rear U hand: the starting position of the S ([丨.. After the small rotary tool 7 reaches the end position and F, hi #赫濞 w, make the small rotation J When the red edge is raised, the spoiler pin F2 is raised from the end position. Although the description is given for the material joining, the false joint project, and the second projecting joint project, the trajectory in each of the B-disks is connected to the project. It can be exemplified only by other examples, but other forms are also possible. Alternatively, the first protruding material bonding process and the Ρ protruding material joining project may be omitted, and only the dummy joint (2-4) under the hole forming process may be omitted and then the lower hole forming process may be performed. The work of the lower hole shape is known, as shown in Fig. 5b, the formation of the lower hole P1 is formed at the start position of the friction stir piece in the surface side joining project. The lower hole opening/warning in the first preparatory work In the project, the purpose of forming the lower hole P1 at the start position Smi of the surface 32 of the second projecting material 3 is to reduce the insertion (four) (m-resistance) of the stirring pin G2 21 of the large-sized rotary machine, and in the present embodiment. In the middle, let the small rotary worker F F stir the pin F2 (refer to the 5a The hole H1 formed at the time of the detachment is formed by reaming the drill bit of Fig. 7Γ. If the hole is removed, the forming process can be simplified, and the working time can be shortened. However, the shape of X P1 is obtained. Although it is not particularly limited, in the present embodiment, it is cylindrical. Further, in the present embodiment, sfe姊, + & -^, although the lower protrusion P3 is formed in the second protrusion 3,

The position of p P1 is not particularly limited and may be formed on the first projecting member 2, and although ° is formed in the merging portion j 2, j 3 , it is preferably formed in the joined metal member i as in the present embodiment. An extension line of the joint (boundary line) of the joined metal member 1 on the surface A side. In addition, in the present embodiment, the hole H1 of the small rotating tool F of the small body F. 2 (',,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, However, the maximum outer diameter X2 of the stirring pin F2 is larger than the minimum outer diameter γ3 of the large-sized rotating pin G2 and the maximum of the stirring pin F2.

仏X2 is smaller than (4) the maximum outer diameter K of the (four) pin G2 (γ3 < χ 2 < γ2). The lower hole η 1 of the σ and 疋 stirring pin F 2 forms a lower hole p i in this state. (3) Surface-side joining process The kneading-side joining process is a process in which the surface side of the surface A side of the joined metal member 1 is actually joined to the 彳 &<# 恻 邛 邛 邛 J1. In the surface side of the present embodiment, the large-sized rotary tool G shown in Fig. 5b is used, and the surface-side protruding portion η of the dummy-like shape is "frictionally stirred" from the joined metal member. In the face-side joining project, as shown in Fig. 8a to Fig., the large-sized rotary ',) stirring pin G2 is inserted (pressed in) into the lower position of 2036~9981-PF; the Chentf Pi point Pi, so that the inserted search The mixing lock G2 does not detach the heart in the middle. That is, the surface of the construction side is joined with the construction towel 'from the lower hole? 1 end of the end of the mixing' and the continuous riding (four) mixing until the end of the 7 friction, the first - the completion of the preparatory work Point, presented j _ 靛 转 F F F F F F F F F F F 具备 具备 具备 具备 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 p p p p p p p p In the side joining process, the large-scale rotary tool (1) is moved to perform the surface-side joining process, which simplifies the work. In addition, in the present embodiment, at the start position Sm) of the second rubbing agitation, the output is set in the output 3 A protruding material 2 soil $ but the starting position. Also i,, -S beam position ... - The position of the beam position is not limited. :: The figure shows the surface side jointing project in more detail. PI (open * as shown in Figure h of the figure 7^', the large rotating tool G is located at the lower hole 1 (starting position Sm) Directly above, the rotating side will drop and the mixing lock G2^ will be turned to the right side to enter... The front end is inserted into the lower hole. When the mixing pin.. ^ enters the next eight P〗, the Lala miscellaneous hole, · ❼ The circumferential surface (side). Abuts the lower hole P1. The second is the plastic flow of the hole wall. When it becomes this form, the plasticity: the pin, the circumference of the 'Gold Mixing G2' is retracted, and at the same time (4), the press-in impedance of the low-pressure initial stage can be reduced. Further, before the shoulder Gi of the large-sized rotary tool G abuts the surface 32 of the seal 3, the pick-up pin G2 abuts against the lower hole pj and is short to plastic. The time of fluidization, that is, the frictional heat can be generated, the load of the friction stirrer can be reduced, and the working time required for the joint of the button can be reduced. The total amount of the G2 is awarded. Entering the second protrusion 3 and the lower end of the shoulder 2036-9981-PF; the entire surface of the Gent of the Chent 29 1359055 surface is in contact with the second protrusion. As shown in the figure 3^8b, the friction is used to make the large-scale rotary work and then the end of the surface side of the first metal member 1 is joined, and the moon is joined and cross-cutted. When the rotary tool G moves, the Jintian around the search lock G2 makes a large movement, and at the position separated from the lock G2 = plastic flow M i庳; 5® / μ t π The plastic is re-hardened to form a plasticized region (hereinafter referred to as "1"), and the plasticized region on the surface side is "". Further, the plasticized region includes a state of being plasticized by the heating of the rotating 〇xa, .y, J thick, and a state of rotating normal temperature. When the revolving tool passes, it returns to the J-degree of the surface-side plasticized region W1. In the present embodiment, the formation of the surface (1) from the top surface A. of the joined metal member 1 to the upper surface of the logic member U1 is struck. It is still big. In other words, the surface-side plasticized region Η is in contact with the connecting member U1, and the friction is searched for the full length in the depth direction of the surface-side protruding portion J1. . The moving speed (conveying speed) of the large-sized rotary keeper G is set in accordance with the size and shape of the lock lock G2, the material and thickness of the joined metal member i such as the friction, and the like. In most cases, it is set in 3 〇 ~ 30 0 (mm / min) within the range. When the amount of heat entering the joined metal member is excessively large, water is supplied from the surface A side to the periphery of the large rotating tool g to be cooled. Further, when the cold water of the field enters between the first metal member 1a and the second metal member 1b, 'the joint surface (the end faces T1, T2, see Fig. 3b) may have an oxide film, and in the present embodiment, Since the dummy joint project 2036-9981-PF and the Chentf 30 1359055 are closed to close the opening, it is difficult for the cooling water to enter the joined metal member without deteriorating the quality of the joint portion. b', at the surface side protrusion η of the joined metal structure #1, the path of the friction is set on the joint of the joined metal member 1 (the pseudo engagement: the movement of the path:) to set the path of the friction stir The large-scale rotation of the path is relatively moved, and the two sides of the surface-side projection are continuously mixed. In making the large (four) tool G relative

After the other end of the side joint portion n, the friction cross-feeding edge crosses the poor six parts j.2, and the relative movement is made toward the end position & ,

In the present embodiment, when the path of the friction stir at the start position of the friction stir at the joint metal line on the surface side of the member 1 is a straight line, the large-scale rotary tool can be effectively joined to the surface side. The amount of wear of the tool G. Due to the elongation of the seam (boundary line) appearing on the joined metal member 1, the surface side can be joined in the work. When the path of the friction stir is constant, the moving distance of G is suppressed to a minimum of 11 steps 'and can be reduced. Low large. Rotation - after the large rotary tool G reaches the end position £Eh], such as the first turn, the large rotation The tool G is raised while rotating, and the stirring pin is disengaged from the beam position E (see Fig. 8b). Further, at the end position - when the lap pin G2 is detached to the upper side, the unplugging hole Q which is inevitably formed in the same shape as the stirring pin is inevitably retained in this embodiment. When the stirring pin G2 of the large-sized rotary tool G is "disengaged from the end position", the rotation speed of the large-diameter tool G (rotation speed at the time of disengagement) is preferably higher than the % rotation speed of the % of the private movement. Thus, when disengaged The rotation speed is the same as that of 2036-9981-PF;chentf 31 '. When the rotation is the same, the phase impedance becomes smaller, and the [u] is used to dissipate the G2 release operation. In the case of the present embodiment, the first preparatory work is performed on the first 褚I τ, j, and the first preparatory work is omitted, and the surface side joining process is performed after the first preparatory work. The second preparatory project calls for the preparatory work to be carried out before the second pre-injury project.

The sequence of the friction mixing of the surface pseudo-jointing project by Bai Xian' is explained in more detail.

The type rotary tool F is located immediately above the start position Sp of the appropriate position of the first protrusion 71, and then the small rotary tool "rotates right side by side" and lowers the stirring pin F2 (refer to FIG. 5a). Pushing to the start position Sp ' The rotation speed of the small rotary tool F is set according to the size and shape of the stirring pin, the #f and the thickness of the metal member 7D to be friction stir, and the like. In most cases, the setting is made. Within the range of 50 0~2〇〇〇(宁).

When the mixing pin F2 comes into contact with the surface of the first projecting material 71, the metal around the pin (four) is plastically fluidized by the frictional heat, and the stirring pin 插入 is inserted into the first projecting member π. When the entire length of the mixing pin F2 enters the lower end surface F11 of the shoulder portion F1 of the first protruding member 7i (refer to FIG. 5a), the entire surface of the first protruding member F11 is contacted with the surface of the first (fourth) member 71. The central portion of the protruding portion m (the false joint p 71 at the middle of the first intersection c71 and the fourth intersection 74) is relatively moved while rotating. The moving speed (transport speed) of the small rotary tool F corresponds to It is set in the size and shape of the stirring pin F2, the material and thickness of the friction stir metal member, etc., but in many cases, it is set in the range of 丨~1 000 (mm/min). In the case of the rotary tool F, the axis of the shoulder F1 is slightly inclined toward the rear in the traveling direction with respect to the lead line. However, if the lead line is not inclined and becomes a lead line, the direction of the small rotary tool can be easily changed, and complicated operations can be performed. 2036-9981-PF; Chentf 78 (3) y〇55 Small rotating tool F relative shape & second, * This person, privately moving the altar, - shell friction stir to the false connection δ starting point ρ7ΐ, after the false connection Connected to pick up; ^ p71 to make the small rotation detached - this state becomes the first one of the protrusions of the non-q hole 4 J71; phase = move., for the part of the protrusion, 71 is the second , seam with the connecting member 7.2◦ (boundary line: / The path of the latter causes the small rotary tool f to make a phase and friction stir the protrusion J71. And, when the small rotary worker (four) mixes the pin ρ2 into the crowd, although it is pulled away from the first protrusion 7 ° ^ 171, The force generated by the μ* material 71 and the connecting member 720 is generated, and the dog output 71 is dissolved in the body portion Q, and no opening is formed between the first protruding member 71 and the metal member m.

After the small-sized rotary tool F is rotated to the second intermediate point W with respect to the second intermediate point, the first end of the protrusion J73 is not separated. According to this state, the friction is given to the protruding portion J76. That is, =C72 is relatively moved, and the second protruding member 72 and the connecting tool F are relatively moved along the path, and the pair is seamed (boundary line). The friction on the upper mixer makes the small rotary tool F::"6" to perform friction mixing. The second one makes the small rotation = to the second intersection. After 72, the other part of the protrusion J.73 does not separate. According to this state, the relative movement is changed to the parent, the parent point c72, and the friction is stirred on the QQft·) — 80 1359055 _ PJ 7 3 . That is, after the friction stir is continuously performed to the first defect c7.2, the friction stir is not ended at the second intersection c72, and the small rotary tool F is caused to follow the joint provided between the second protrusion 72 and the body portion q ( The friction stirrer path on the boundary line is moved relative to each other, and the friction part is 摩擦 agitated. r is relatively moved to the first: intersection point c73 so that the small rotary tool F does not detach, and in this state, the third intermediate point m73 of the projection portion m provided on the body portion q of the first projection member 72 and the second metal member mb is opposed to Move, and stir the mixture to the junction. That is, after the friction stir is continuously performed until the third intersection c73 which is the other end of the protruding portion J73, the third intersection c73 is beamed, and the small rotary tool F is placed along the second projection 72. : On the joint (boundary line) (4) the fresh-fresh path is moved relatively, and the dog & part J 7 7 is subjected to friction mixing. A ' ^ 吏 small rotating tool F relatively moved to the third intermediate point (four) ^ at: three intermediate points m73 to make the small rotating tool " detached according to this shape two protruding material 72, the second protruding material" (4) The movement of the small rotary tool F from the third intermediate point to the second protrusion M is set to the end of the protrusion J74. The parent point c73 returns the small rotation tool F to ^ The intersection point C73 makes a small rotating tool.

After 73, the friction mixing path is set on the joint (boundary line) of the body portion 另 of the other metal/710 and the connecting member 72G, and the "Hai path causes the small rotating tool F to move relative to each other and friction stir. After the small rotary tool F is relatively moved to the fourth intersection c74, the small rotary tool F is not disengaged at the two intersections C74, and the first displacement: the material 71 is protruded in this state, and the first projection: the output 71 is frictionally mixed. At the same time, the fourth intermediate point m74 of the second (10) of the body portion q of the first protruding material η and the other metal member 71.

The protruding material 71 is frictionally agitated, and the relative movement of the small-sized rotating tool F reaches the end position Ep. After the small rotary tool F reaches the end position Ep, the small rotary tool F is rotated while being raised to make the sandalwood lock ρ2 (see 5&; Fig.) is detached from the end position Ep. When I rotates the small rotary tool F to the right, since there is a joint defect on the left side in the traveling direction of the small rotary I tool F, the protrusion, the 72, and the connection are provided. The protruding portion m of the member 72〇, the 73 and the protruding seal W 72. When the protrusion part·m to J78 of the main body part Q is mixed (four), the path of the "undefined friction mixing" causes the protrusion 7 (1) to stand on the left side of the rotation direction of the type F: that is, When the small rotary tool ρ is rotated right, it is preferable to make the friction from the false engagement start point P71 to the false engagement end point p72 halfway. It is also determined that the small rotary tool F is moved along the outer m of the connecting member (10). Since it is difficult to cause a joint defect on the side of the connecting member 720, a high-quality joined body can be obtained. 'When the small rotary tool F is rotated to the left, since there is a joint defect on the right side in the traveling direction of the small slave tool F, Friction search 2036-9981-PF along the protruding portion of the dog output 71 72 and the connecting member 72〇, J73 and the protruding material Π72 and the protruding portion of the body portion Q75~78; Chentf 83 1359055 The path of the friction stir is set to the right side of the traveling direction of the turning tool F.

The inner corner portion of the joined metal structure 0 and the protruding member 750 is opened and closed to prevent friction stir. The surface (top surface) and the inner surface (lower surface) of the material 750 are: the first side surface C of the joined metal member 70 and the second side surface D (see Fig. 31) are flush. In the first side jointing work, Small rotary tool =::::Γ starting position " along the first side - side two ρ relatively moves to the end position ^. In the real (four) state = tool F rotates right to perform the first-side joint joining project. Two:: = tool F pushes the pressing start position SM3, then moves to the _ side of the ...... After that, the small rotary tool F is moved. The large mouth P J72 is moved. At this time, since the small rotary tool f is frictionally mixed in the first plasticized region W72, the first side is connected to the manual and the process. And the side plasticized zone of the friction stir. The area W72 is repeated. 75, "Surface plasticization after the small rotary tool f reaches the corner point k72, the virtual number below the m 7 2 0 - all belong to the 7th member" The protrusion 2036-9981-PF of the surface 716 of the segment R of the metal member 710a; the 下面hentf 88 1359055 the joint J710 and the lower surface of the connecting member 720 are frictionally stirred with the second metal member, the protruding portion J711 of the surface 716 of the segment R . At this time, the 2-type rotary tool F performs friction-scraping in the first-stage plasticized region W71, and the friction-stirred side plasticized region W75 and the first-stage plasticized region W71 are formed by the first side joining process. repeat. After the small rotary tool F reaches the corner point k73, friction stir is performed along the protruding portion j74. Then, in the small rotation tool? After reaching the end point kM, the small rotary tool F is moved to the end position in this state, and the small rotary keeper W is released from the β at this time. Since the small rotary tool F is frictionally stirred in the second surface plasticized region W73, The frictionally agitated side plasticized region f75 and the second surface plasticized region W 7 3 are repeated by the first side joining process. Further, the start position 1 and the end position Ε „3' are preferably set on the extension line of the projection portion J7.2 or J74 as shown in Fig. 4a, whereby the small rotary tool F can be moved in the shortest distance. According to the first side joining work, the joint portion exposing the first side surface C is frictionally agitated by continuous running, and the work can be performed efficiently. Here, in the above-described surface joint joining process, the joined metal member is formed. The oxide film between the first protrusion 71 and the second protrusion 72 may be caught in the interior of the joined metal member 70. The oxide film described above is a gas-tight and water-tight property of the joined metal member 70. One of the reasons. However, according to the first side bonding process, in the first surface plasticized region W72 and the second surface plasticized region W73, the oxide film of the first side surface c is hermetically sealed, and the airtightness can be surely improved.

Here, when the protruding portions J72 and j74 exposing the joined metal member 7〇 are frictionally removed, it is possible to form a communication from the first side to the second side. Tunnel-like void defect of D (hereinafter referred to as tunnel-shaped void defect). The above-mentioned void-like void defect is the airtightness of the joined metal member 7〇^-QQQT-D1T. 广1K〇r> and ^ 90 The main course of the reduction of water and water tightness, but the reason for the smashing of the Jin, according to the embodiment of the joint work tool:;: Fang Feng: the defect of the first-line defect due to the rotation of the cyclone :::: One set is different. In each i^~F iM- ί 4-j,- there are various combinations in the direction of travel. The combination will be described in detail below. That is, the friction stir gap defect may be formed: = the tool moves to the right and the left side rotates, and the left side rotates the "$face' so that the rotary worker is plated there, in order to be appropriate: the crucible can be formed on the right side in the traveling direction. The tunnel-shaped cavity defect is buried in the ground, and is divided into a first pattern and a second pattern.

Fig. 41 is a perspective view showing a joining method of the side joining work, and Fig. 4 is a view showing the second pattern in the first pattern 14ib. In the figure, the direction from the first side C is shown as the direction of the second side D side is the traveling direction N, and the opposite direction of the line is the traveling direction N. 〇 <first pattern 〉 The first pattern </ br> The type of the two metal members 710b. That is, in the first side member c, the state in which the tunnel-shaped void defect 790a is formed on the first metal member 71〇3 is (in the case of) the rotary tool is set to the right rotation in the traveling direction N, ) The case where the left direction is rotated in the traveling direction. 91 1359055 On the other hand, in the first side surface c, in the state in which the tunnel-shaped void defect 790b is formed on the second metal member 71〇b, (1_3) when the rotary tool is set to rotate rightward in the traveling direction N2, (1-4) The direction β of the left rotation is set in the traveling direction 1. Therefore, in the surface bonding process, the pattern of the first drawing has the above four methods. Next, the side joining work for the case of the first pattern will be described. As shown in Figure 4.1a, on the end face of the protruding material 75〇, the starting position

One of the base point (1) or the base point 〇2 which is set to a point on the extension line of the protruding portion J72 or the protruding portion J74 is set. When the starting position of the side joining project is set at the base point 0, it is preferable to rotate the rotating tool F to the right to perform friction feeding. Gp, when the starting position is set at the base point 〇] and the rotary tool is set to the right rotation to perform the side joining process, the right side of the traveling direction is reliably frictionally agitated, and the tangential cavity defects 79 〇 &amp; 790b can be reliably sealed. . When the starting position of the side joining work is set at its point, it is preferable to rotate the rotating tool F to the left to perform friction stir. That is, when the start position is set: the base point 02 and the rotary tool is set to the left rotation to perform the side surface, the left side of the traveling material is moved to the left side of the traveling direction, and the tunnel-shaped cavity defects 790a and 790b can be reliably sealed. As described above, in the first pattern, it is appropriate to use the side-by-side joint project to "close the lane-shaped void defect 79Qa. Therefore, in the first pattern, if there are eight kinds of joining methods in consideration of the surface bonding work, the tunnel-shaped void defects can be appropriately sealed. Next, the second pattern is illustrated for the second pattern. As shown in FIG. 41b, FIG. 92 1359055', the tunnel-shaped void defects 790a, 790b formed in the first surface plasticized region W72 and the second surface plasticized region W73 are formed in the connection. The type of the interior of member 720. That is, in the first side face C, the state formed on the connecting member 72A with the track-shaped hole defect 709 is (2-1) in the protruding portion J7 2, the rotary tool is set in the traveling direction N! In the case of rotating to the left, (2-2) in the case of the protrusion J 7.2, the rotation tool is set to rotate rightward in the traveling direction N2. φ On the other hand, in the first side surface c, the state in which the tunnel-shaped void defect 790b is formed on the connecting member 720 is (.2-3) in the protruding portion J74, and the rotary tool is set to the right rotation in the traveling direction N1. In the case of (2 to), in the protruding portion J74, the direction of the left rotation is set in the traveling direction Nr. Therefore, in the surface bonding process, the pattern of the second pattern has the above four methods. Next, the side joining work for the case of the second pattern will be described. As shown in Fig. 41 b, the start position is set to one of the base point 0 or one of the base points 〇 2 which is a point on the extension line of the projection portion J72 or the projection portion j74 on the one end surface of the projection material 75 5 。. When the starting position of the side joining project is set at the base point (1), it is preferable to rotate the rotating tool F to the left to perform friction stir. In other words, when the start position is set to the base point 〇1 and the twirling tool is set to the left rotation to perform the side joint joining process, the left side of the traveling direction is reliably frictionally agitated, and the tangential cavity defect 790a can be surely closed.

In the case of Xp, the starting position of the g-side joining project is set at a certain point. ^ It is preferable to rotate the rotating tool F to the right to perform friction stirring. In other words, when the opening position 93 is opened at the base point 〇2 and the rotary tool is set to the right rotation to perform the side joining process, the right side of the traveling direction is reliably frictionally agitated, and the tunnel-shaped cavity defect 79 can be surely closed. 〇a, 7g〇b. As described above, in the second pattern, there are two methods for appropriately sealing the tunnel-shaped cavity defects 79〇a, 79〇b in the side joining process. Therefore, in the first pattern, it is possible to appropriately seal the tunnel-shaped void defect in consideration of all the bonding methods in the surface bonding process. [Seventh embodiment] Fig. 40b is a side view showing the seventh embodiment from the first side view. The seventh embodiment of the joined metal member 7 is the first metal member 7.10a and the second metal. The feature that the height of the segment portion R of the member 71〇b is large is different from that of the sixth embodiment. That is, in the case where the height of the protruding portion of the segment portions R and 7 2 〇 is large, it is difficult to repeat the first segment plasticized region W71 and the second segment plasticized region. In this case, in the side joining work, it is preferable to frictionally agitate the projection portion J72c, that is, as shown in Fig. 40b, the side surface joining work of the seventh embodiment further includes the work of the friction stir welding portion J72. In the side joining work of the seventh embodiment, in addition to the projecting material 750 which is bottomed to the surface A of the joined metal member 7A, the projecting material 760 abutting on the inner surface B side is disposed. The surface (upper surface) and the inner surface (lower surface) of the protruding material are formed flush with the first side surface c and the second side surface D of the joined metal member 70. A side-by-side jointing work of a seventh embodiment is to set a starting position in the S&quot; in the first protruding member 750 to make a small rotary tool? The right rotation is along the 2〇36-998l-PF; the Chentf 94 1359055 is the extension of the Chuanhe and then moves. Then, after the small rotary worker F reaches the abutment point k75 of the first metal member (10), the second metal member (10), and the connecting member (10), the friction stir is performed along the protruding portion J72. After the motor (4) is reached over the entire length of the protruding portion (10), the small-sized rotary machine is moved to the turning-back point set at the protrusion #76〇 without departing. - Then, the small rotary tool F is re-expanded into the protruding portion 20' without moving out, and the small rotary tool F is moved to the abutment point π, and then the frictional engagement portion mi and the protruding portion claw are moved to the end position Eh" according to In the second embodiment of the present invention described above, the height of the segment portion R becomes larger. Even in the case where the first-stage plasticized region W71 and the second-stage plasticized region m cannot be overlapped, the plasticity of the side surface is made. The plasticized zone tW71 and the second non-plasticized zone w74 of the first region of the region are repeatedly slidable over the entire length of the protrusion J7.20. Thereby, the watertightness and gas between the sides of the metal member 7D can be improved. Further, since the friction stir welding is performed in a continuous trajectory, the work can be performed efficiently. Although the above description is directed to the embodiment of the present invention, the present invention is not limited to the above-described type, and does not violate The object of the present invention is appropriately changed. For example, in the sixth embodiment, in the sixth embodiment, although the frictional sandfall is performed on both sides of the first side surface C and the second side surface D, only one of them may be performed.
