The formation of the lower hole is as shown in Fig. 3, which is the construction of the lower hole at the beginning of the friction stir in the joint-joint project. In the lower hole forming process in the first preparatory work: the lower hole P1 is formed in the SMi set on the surface 22 of the first protruding material 2. The purpose of the lower hole P1 is to reduce the insertion resistance (pressing impedance) of the stirring pin G2 of the joining rotary tool G. In the present embodiment, the stirring pin F2 of the dummy joining rotary tool F (see the fourth ( a) The pull hole H1 formed when the detachment is formed is formed by reaming a drill (not shown). If the hole m' is used, the work of forming the lower hole P1 can be simplified, and the working time can be shortened. 2036-9751-PF; Chentf 23 200902203 Although the form of the lower eight P1 is not particularly limited to the Yue Yuhu j, it is cylindrical in the present embodiment. Further, in the present embodiment, the position of the hole in the lower portion of the first projecting material 2 is not particularly limited, and the second projecting member 3 may be formed in the protruding portion. In the present embodiment, it is preferably formed on the extension line of the joint (boundary line) of the joined metal member 1 on the surface A side of the joined metal member 1. In the present embodiment, the hole (1) of the mixing lock F2 (see Fig. 4U) of the false engagement rotary machine F is reamed to form a lower hole. In the case of <column, the maximum outer diameter χ2 of the agitating lock F2 is larger than the minimum outer diameter a γ, the radix * 扛 Y3 of the mixing pin g 2 of the joining rotary tool G, and is in the stirring pin ^ When the outer diameter X1 is smaller than the maximum outer diameter Υ2 of the stirring pin G2 of the boring tool G for joining, the lower hole π of the mixed money can still form the lower hole p1. (3) First joining work * The first joining work is a process of actually joining the large-side joint portion 11 on the surface of the joined metal structure. In the first joining process of the present embodiment, the present welding rotary tool shown in Fig. 4 (f) is used to rub the protruding portion J1 in the state of the ytterbium joint from the surface side of the joined metal member i. Stir. In the first-joining project, the technique is as follows: (as shown in Fig. 0), the cutting tool G2 is inserted into the starting position & = the intervening pin is inserted. And moving to the end position, that is, in the first joint project, the friction stir is continuously performed from the lower hole to the end of the position & 1 〇36-9751-PF;chentf 24 200902203 At the time when the first preparatory work is completed, the friction stirrer having the dummy joining rotary tool F is located directly above the knot of the first protruding material 2 (see FIG. 6), if the first joining work The starting position is sM1, and the first (4) mixing device including the joining rotary tool G is moved without moving, and the work can be omitted. Further, in the present embodiment, the first protruding member 2 is frictionally stirred. At the start position SM1, the end position E*" ' is provided on the second protrusion 3, but the positions of the start position Smi and the end position £ & are not limited. Referring to Figures 7(a) to 7(c) in more detail Explain the first joint project. Watson, as shown in Figure 7(a) It is shown that the joining rotary machine W is located immediately above the lower hole P1 (starting position Smi). Then, the joining rotary machine is used, and the G side is rotated to the right side, and the front end of the mixing pin G2 is inserted into the lower hole stirring lock. When G2 enters the lower hole pi, the circumferential surface (side) of the seeding (4) is attached to the wall of the hole. The metal begins to plastically flow from the six walls. When it becomes this, the plasticized metal flows. When the circumferential surface of the mixing pin G2 is retracted by the stirring lock G2, the dust input impedance at the initial stage of the repetition can be reduced, and the shoulder G1 of the joining rotary tool G abuts against the first protrusion: the surface 22 The mixing (4) abuts the lower hole ρι to generate frictional heat, and can shorten the time to plastic fluidization. That is, the reduction of the frictional load can also shorten the working time required for the jointing project. After the whole of the first protruding material enters the first protruding material "and the shoulder end surface (1) is in full contact with the surface 22 of the first protruding village 2, as shown in the seventh (8) figure, the side frictional (four) side is used to make the joining rotary guard to be engaged. The protrusion of the metal member 1 ...-ends relative movement, and 2036-9 7 51-PF,· Chen Tf 25 200902203 and 'crossing the protruding portion J2 and projecting into the protruding portion J1. When the joining rotary tool G is moved, the metal around the stirring pin G2 is plastically fluidized in order, and at the position separated from the stirring pin G2, The plastic fluidized metal is hardened again to form a plasticized region (hereinafter referred to as "surface-side plasticized region W1"). The moving speed (transport speed) of the joining rotary tool G corresponds to the size and shape of the stirring pin G2. The materials and thicknesses of the joined metal members 1 and the like which are frictionally stirred are set, but in many cases, they are set in the range of 30 to 30 0 (_/min). It is preferable to supply ice from the surface A side to the periphery of the joining rotary tool G and to cool it while entering the joined metal member ... Wang η -----/ open rv". Further, when the cooling water enters between the first metal member 1a and the second metal member 1b, the oxide film is formed on the joint surface (see the end faces 11a, 11b, and (b)), and in the present embodiment, The hole between the joined metal members 1 is blocked by the dummy joint work, and the cooling water = the flow between the metal meal 1 and the joint portion is not deteriorated. The joined metal member π - J VIII β σ | " A The path of the m-handle agitation - the seam set on the joined metal member i (the pseudo-joining movement trajectory illusion 'by moving the joint along the path, from the end of the shackle to the other surname, ..."

Since the private distance of the joint rotary machine 1 Gg I 4 ～ 6 Μ G is minimized, the efficiency of the first cooperating worker f0 can be effectively performed, and the suspicion of the joint can be reduced. The amount of wear of the transfer tool G. When the joining rotary tool G reaches the end position...the temple is not shown in Fig. 7, the joining rotary work 9 is made to rise far, and the stirring lock end position is Ε>" (refer to the figure (10) ) detached. Further, if the agitating lock G2 is disengaged to the upper side, the second forming of the same shape as the pinning pin G2 is still retained. * This "also forge the rotation tool of the joint" "The lock speed G2 is removed from the end position ^. The rotation speed of the joint turning partner G (the rotation speed at the time of disengagement is better than the rotation speed at the time of movement). In comparison with the case where the rotation at the time of the detachment is the same as the case where the rotation speed at the time of the movement is the same, the detachment of the end position & G2 can be quickly performed due to the release of the distribution pin (four) resistance. In the present embodiment, after the first preparatory work is omitted, the first joint work is performed immediately after the first preparatory work is omitted. 2. Prepare the engineering process.

As shown in Fig. 14(b), when the fourth bonding is performed The material-side, the surface-side plasticized region W1 and the second-side plasticized region W2 on the second side D side overlap with the second side-side plasticized region f4, that is, by the surface-side plasticized region π and the back side plasticity Part of the W2 area By friction stir, at least a part of the void defect Ri and the void defect on the second side D side is broken by the second side D side plasticized region W4. Thereby, the filling portion 1 is formed on the void defect R! and the void defect, respectively. , S4. And 'Before the fourth joint project, the lower hole forming project = 2-1 is omitted.) The third joint project can also be directly performed after the third joint project. X ' in the fourth joint project Previously, the above-mentioned 2036-9751-PF/Chentf 37 200902203 can be used to produce the sigma buckle, the false joint project, and the second projecting joint project. (14) The protruding material removal project is in the prominent village resection project, in the fourth After the completion of the joining process, the first dog material 2 and the first protruding material 3 are cut off from the joined metal member 1 (multiple, first drawing). At this time, it is preferable to remove the burrs formed on the surface Α of the joined metal member 1 and the inside β. According to the bonding method of the present embodiment described above, as shown in FIG. 1, as shown in FIG. 1, even if the first metal member 1a and the second metal member 1b are thick, the first side and the second side are The side surface D is subjected to friction stir to embed a continuous gap from the first side surface c to the second side surface D (refer to the gap 1 j 9 in FIG. 30). When the rotation direction and the traveling direction of the joining rotary tool G are set to the above-described state, the surface side plasticized region W1 and the back side plasticized region W2 are traversed from the first side surface C to the first side. The two side faces D form a continuous cavity lacking m Rl, R2, and the start position of the fourth bonding work is set by setting the start position SM3 of the third joining process to the starting position & side of the first joining work. s "Setting on the center 2 side of the second joining process to perform friction feeding, and forming the filling portions S1 to S4 for breaking the cavity defects R1 and R2, respectively. Since the rotation direction of the rotary tool G is all set to the right rotation, the void defect R is plasticized on the surface side: the possibility of the left side of the traveling direction of the domain]π and the inner plasticized region W2 becomes higher, and the right side forms the density of the traveling direction. Higher plasticized area.

The fourth bonding process is in addition to < The rest is roughly the same as the third joining project 2036-975l-pF; and the Chentf 58 200902203 is the same as 'omitted.' and after the end of the fourth joining work, a pair of protruding members are cut off from the joined metal member 201. According to the bonding method of the embodiment described above, as shown in Figs. 24 and 25 The first side plasticized region W23 and the second lateral plasticized region W24 in the first side surface C and the second side surface D are formed by plane linear shapes L1, L2, and L3. The sum of the extended distances is larger than the length lh of the joined metal member 2〇1, and the friction stirrable region is ensured to be long. Therefore, the stress acting on the joint portion of the joined metal member 201 is dispersed to improve the joint strength. According to the third joint work and the fourth joint work, the surface-side plasticized region and the inner plasticized region W22 are overlapped with the first side plasticized region m and the second lateral plasticized region W24, and - the side surface. The total length of the protrusion portion J21 of the second side surface D is frictionally imparted to the joint surface. Thus, the airtightness and watertightness of the metal member 2〇1 to be joined can be achieved. In the present embodiment, the shape u and the plane line shape L2 are formed in the present embodiment, because the protrusion portion J21 is made straight, and σ is formed in the protrusion surface. Twist The flat line is secret.... fj ^ 'At the bending point C2, when the flat ice shape L2 is engaged with the plane linear L3 shape, the Hu Bo * person stands, therefore, the friction stirs the G by: reaching: the large rotation of the plane linear movement The work G is stopped because it reaches the bending points C1 and C2, and the other parts are subjected to friction for a longer period of time. The sounds of the two songs i and C2 will be mixed with C2' by long-term friction. =: The curved point 1 is processed, and the airtightness and watertightness can be improved at the joint. Defective ground 2036-9751-PF; Chentf 59 200902203 Further, in the fourth embodiment, in the first joint project and the second This joining process _ φ , _ (, 'Because the joint 5 is rotated right by the rotary tool G, the hole can be opened on the side of the surface plasticized region W21 and the inner plasticized region w22 at /tL n rv η , ^ Defect (pattern omitted). Here, in the third joining work, the joining rotary tool is rotated to the left, and the second metal member 2 〇1 b side is subjected to the higher density friction from the inside b to the table. Further, in the fourth joining process, the joining rotary tool g is rotated, and the inside β is moved toward the surface A, whereby the second metal member u side performs high-density friction searching. Thereby, the void defects which may be formed in the first-joining work and the first joining work can be broken in the real place. Further, by using the projecting material, the first joining process, the second joining work, the third joining work, and the fourth joining work can be performed correctly and quickly. Further, by the false engagement of the respective protruding members with the joined metal member 2〇1, it is possible to prevent the occurrence of the opening when the first joining work, the second joining work, the third joining work, and the fourth joining work are performed. Further, in the present embodiment, the side joining process is performed on both the first side surface C and the second side surface, and it is not necessary to perform the two sides, and it may be performed at least on one side. Although the present invention has been described in terms of preferred embodiments, the invention is not limited to the above-described embodiments, and the appropriate design can be changed without departing from the scope of the present invention. The protruding portion J21 of the second surface D and the second side surface D are not limited to the planar shape of the fourth embodiment, and can be appropriately set. In other words, in the embodiment, the planar straight line shape of the protruding portion J21 'the protruding portion J21 formed by the combination of the three planar linear lines LbU'U and the two points C1'C2^2036-9751-PF; and the combination of the Chentf 60 200902203 is formed The thickness of the joint metal member 2〇1 is also large, and the shape of the projecting portion J21 is not limited to the above-described embodiment, and can be appropriately set. Fig. 26 is a plan view showing a first side surface c of a modification of the embodiment of the present invention, wherein (a) is a first modification, (b) is a second modification, and (c) is a second modification. For example, as shown in Fig. 26(a), the protruding portion J22 is disposed to be inclined with respect to the thickness direction of the joined metal member 20A, whereby the protruding portion J22 can be formed without providing the bending point, and the protruding portion J22 can be secured. The thickness (4) of the joined metal member 201 is a large flat line [length of extension. According to the above-described protrusion portion J22, since the extension length of the plane line shape 1 for performing friction feeding is longer than the thickness ih of the metal member 2〇1 to be joined, it is possible to ensure a long distance between the friction stir and a high joint strength. Further, as the projections J23 and J24 shown in Fig. 26(b) or 26(c), a combination of two planar linear shapes u and L2 and a bending point U may be used. According to such a configuration, the large-sized rotary gaist G of the heart stops when it reaches the bending point U. The above-mentioned type of cancer shows the same, but the friction stir is actually performed. Moreover, in this case, the angle of the inner corner of the bending point W The present invention is not limited, and may be appropriately set. Fig. 27 is a plan view showing a first side surface C of a modification of the embodiment of the present invention, (4) is a fourth modification, (b) is a fifth modification, and (c) It is a sixth modification, and (d) is a seventh modification. In the fourth embodiment, although the angles intersected in the plane line shape LI, L2 or plane 2036-9751-PF; and the line L2 and L3 of the Chent 200902203 are right angles. The bending point and C2 are set at two positions, but the angles of the bending points ci and C2 are not limited. For example, as shown in the projections J25 and J26 shown in Figs. 27(a) and 27(b), The bending point, the plane line shape L1, L2 on C2' or the plane line shape L2, u intersect at an angle of 120 degrees can also achieve the same effect. Also, the number of plane-shaped bending points of the protrusion portion can be two The above position may be formed as 'appropriately set. For example, the protruding portion m and the second portion as shown in the figure f 27 (c) 7(4) The protruding portion m shown in the figure may have four or six bending points. Thus, the number of bending points increases the force of the opening, making the moving speed of the large rotating tool G slower or making a large rotation. The movement of the tool G is stopped a plurality of times, and the joining of the joined metal members is performed more reliably, and joining with excellent joint strength, airtightness, and watertightness can be performed. Fig. 28 is a modification of the embodiment of the present invention. The plan view of the first side face C is an eighth modification. In the fourth embodiment, the protrusion portion J21 is formed by a combination of three plane linear shapes L1, L2, and L3, as shown in the figure, The plane linear shape of the joint portion J8 is formed by the protrusion portion. The shape of the flat line is longer than the thickness of the metal member to be joined 2 and the curved line shape is formed when the plane of the joint portion is curved. It is not limited to the linear shape.
