Furthermore, the terms "first," "second," and the like, are used merely for distinguishing between descriptions and not for distinguishing between them.
In this embodiment, a panel welding method and a ship welded by the panel welding method are provided, the ship comprises a plurality of first steel plates and a plurality of second steel plates, the structures and the sizes of the first steel plates and the second steel plates are identical, and the ship adopts the panel welding method to connect the plurality of first steel plates and the plurality of second steel plates.
Specifically, as shown in fig. 1 to 4, the panel welding method comprises the following steps: s10: a first side 11 of the first steel plate 1 is provided with a protruding block 3 extending along a first direction, a second side of the second steel plate 2 is provided with a clamping groove 4 extending along the first direction, and the first direction is the same as the length direction of the first steel plate 1 or the second steel plate 2; s20: the convex block 3 is clamped into the clamping groove 4, and the first side face 11 and the second side face are mutually abutted so as to connect the first steel plate 1 and the second steel plate 2 once; s30: the portion of the first side 11 where the bump 3 is not provided and the portion of the second side where the card slot 4 is not provided are welded to secondarily connect the first steel sheet 1 and the second steel sheet 2.
The first steel plate 1 and the second steel plate 2 can be connected once by firstly clamping the convex blocks 3 on the first steel plate 1 in the clamping grooves 4 on the second steel plate 2 and mutually abutting the first side surfaces 11 of the first steel plate 1 and the second side surfaces of the second steel plate 2; then welding the part of the first side surface 11 of the first steel plate 1, which is not provided with the convex blocks 3, and the part of the second side surface of the second steel plate 2, which is not provided with the clamping grooves 4, so as to carry out secondary connection on the first steel plate 1 and the second steel plate 2, thereby completing connection between the first steel plate 1 and the second steel plate 2; in this way, the first steel plate 1 and the second steel plate 2 are connected in advance by clamping, and then the first steel plate 1 and the second steel plate 2 are welded; compared with the pure welding mode adopted in the prior art, the method can save the welding material consumption required by welding so as to reduce the welding material consumption required by welding; in addition, for the first steel plate 1 and the second steel plate 2 with thicker thickness, a Y-shaped groove or an X-shaped groove is not required to be formed on the first steel plate 1 and the second steel plate 2 before welding, so that the welding material consumption required by welding is prevented from being further increased due to the formation of the grooves, and the welding material consumption required by welding can be further reduced; meanwhile, since the change of the grooves on the first and second steel plates 1 and 2 is not required to be considered any more at the time of welding, the required welding time is short, so that the welding efficiency is high.
Moreover, since the first steel plate 1 and the second steel plate 2 in the present embodiment are connected with each other twice, the first connection is the connection between the bump 3 and the clamping groove 4, and the second connection is welding; compared with a pure welding mode in which only a melted welding material is used as an adhesive in the prior art, the jointed plate welding method in the embodiment has a more compact connecting effect on the first steel plate 1 and the second steel plate 2, and can enable the connection firmness between the first steel plate 1 and the second steel plate 2 to be better.
The ship in the embodiment adopts the jointed board welding method to weld, so that the welding material consumption required during welding can be reduced, and the welding cost is saved, so that the construction cost of the ship is lower; and the required welding time is shorter, so that the welding efficiency is higher, and the construction period of the ship is shorter.
Further, the extension length of the protruding block 3 on the first side surface 11 is the same as the length of the first steel plate 1, and the extension length of the clamping groove 4 on the second side surface is the same as the length of the second steel plate 2 and the extension length of the protruding block 3, so that the lengths of the protruding block 3 and the clamping groove 4 can be at the maximum value, the clamping area between the clamping groove 4 and the protruding block 3 is increased, the clamping between the protruding block 3 and the clamping groove 4 is further tight, and the connection firmness between the first steel plate 1 and the second steel plate 2 is further ensured.
Specifically, in step S10, the projection 3 is provided on the first side 11 of the first steel plate 1 according to the thickness of the first steel plate 1, and the locking groove 4 is provided on the second side of the second steel plate 2 according to the thickness of the second steel plate 2; that is, the sizes and shapes of the protruding blocks 3 and the clamping grooves 4 need to be adaptively adjusted according to the thicknesses of the first steel plate 1 and the second steel plate 2 to be connected, so that the stress born by the first steel plate 1 and the second steel plate 2 is smaller when the protruding blocks 3 are clamped in the clamping grooves 4, and further the welding work can be facilitated, and the welding effect can be better due to the fact that the welding material consumption used during welding is smaller.
Further, as shown in fig. 2 to 4, the bump 3 is formed with a third side 31 and two fourth sides 32, the third side 31 is disposed parallel to the first side 11, and the third side 31 is disposed in a direction away from the first side 11, that is, a space is provided between the first side 11 and the third side 31; the two fourth side surfaces 32 are respectively positioned on two opposite sides of the third side surface 31, each fourth side surface 32 is obliquely arranged between the first side surface 11 and the third side surface 31, and the two fourth side surfaces 32 are in a V-shaped structure; the bump 3 has structural parameters L, W and θ related to a thickness value H of the first steel plate 1, L is a length of the third side 31 in the second direction, W is a distance between two connection points between the two fourth side 32 and the first side 11 in the second direction, and θ is an included angle between the third side 31 and the fourth side 32. The second direction is the same as the thickness direction of the first steel sheet 1, and is specifically shown by an arrow B in fig. 4.
The structural parameters of the clamping groove 4 are matched with the structural parameters of the protruding block 3, so that after the protruding block 3 is clamped in the clamping groove 4, the first side 11 of the first steel plate 1 can be completely abutted with the second side of the second steel plate 2.
Further, the structural parameters of the clamping groove 4 and the structural parameters of the protruding block 3 are obtained through finite element analysis; specifically, first, finite element models of the first steel plate 1 and the second steel plate 2 are built, and since L, W and θ both act on the stress suffered by the first steel plate 1, some of the three variables L, W and θ need to be defined as constants, and then the other parameters are controlled to realize orderly change of the shape of the bump 3, so that a stress change curve of the first steel plate 1 is drawn, so as to seek the optimal structural parameters L, W and θ.
Specifically, it is defined that L, W is constant, and by controlling the change of θ, the first steel plate 1 fluctuates with the change of θ, and the maximum stress value fluctuates and rises from the middle to the two sides when θ is between 42 ° and 56 °; the change trend of the second steel plate 2 along with theta is the same as that of the first steel plate 1; thus, it is possible to obtain, by finite element analysis, that when the value of θ is in the vicinity of 48 °, a smaller stress value can be obtained for both the first steel sheet 1 and the second steel sheet 2.
Further, θ is redefined as a constant, and as can be seen by controlling L, W changes, the stress values of the first steel plate 1 and the second steel plate 2 each show a tendency of being approximately U-shaped when the L, W value is gradually increased, so that when the stress values of the first steel plate 1 and the second steel plate 2 are minimum, the corresponding L value is 9mm, and the W value is 4mm.
That is, it is obtained by finite element analysis of the first steel plate 1 and the second steel plate 2, when the thickness values of the first steel plate 1 and the second steel plate 2 are 15mm, the structural parameters L, W and θ are l=9mm, w=4mm, and θ=48°, the stress values to which the first steel plate 1 and the second steel plate 2 are subjected are minimum, and at this time, the clamping effect between the bump 3 and the clamping groove 4 is the best, which is most favorable for the welding operation.
Specifically, the structural parameters of the bump 3 are obtained by performing finite element analysis on the first steel plate 1 and the second steel plate 2 to obtain the structural parameters of the bump 3(Unit mm),/>(Unit mm),/>(In degrees) so that the stress to which the first steel sheet 1 and the second steel sheet 2 are subjected during the joining process can be minimized, and the joining between the first steel sheet 1 and the second steel sheet 2 can be made to have good joining firmness.
The specific welding process of the panel welding method in this embodiment is as follows:
First, according to the thickness values H of the first steel plate 1 and the second steel plate 2, and Calculating the sizes of the protruding block 3 and the clamping groove 4; based on the calculated structural parameters L, W and θ, a bump 3 is formed on the first side 11 of the first steel plate 1, and a groove 4 is formed on the second steel plate 2.
Then, the bump 3 is engaged in the engagement groove 4 so that the first side surface 11 of the first steel plate 1 and the second side surface of the second steel plate 2 are brought into contact with each other to connect the first steel plate 1 and the second steel plate 2 at a time.
Finally, the part of the first side surface 11, on which the protruding block 3 is not arranged, and the part of the second side surface, on which the clamping groove 4 is not arranged, are welded, so that the first steel plate 1 and the second steel plate 2 are connected for the second time, and the connection between the first steel plate 1 and the second steel plate 2 is realized, so that the whole welding process of the first steel plate 1 and the second steel plate 2 is completed.
The foregoing is merely exemplary of the present invention, and those skilled in the art should not be considered as limiting the invention, since modifications may be made in the specific embodiments and application scope of the invention in light of the teachings of the present invention.
