Specifically, the base 10 is provided with a first limiting groove 12, where the first limiting groove 12 is used for placing a first part to be welded a to limit the circumference of the first part to be welded a, so that the subsequent alignment of the first part to be welded a and the second part to be welded B is facilitated.
Further, a supporting table (not shown) is disposed along the sidewall of the first limiting groove 12 in the first limiting groove 12, and the supporting table is used for supporting the first part to be welded a, so that the first part to be welded a is suspended relative to the bottom of the first limiting groove 12, and further damage to the first part to be welded a can be avoided.
For example, the first part to be welded a is a circuit board, and multiple electronic components are disposed on two sides of the first part to be welded a, and the electronic components are easily damaged by extrusion, so that the first part to be welded a is disposed in the first limiting groove 12 and supported by the supporting table, and the electronic components on the first part to be welded a are prevented from being damaged by extrusion of the base 10.
The support platforms may be disposed annularly along the side wall of the first limiting groove 12, or a plurality of support platforms may be disposed annularly and uniformly along the side wall of the first limiting groove 12, which is not limited in the present application.

The second positioning piece 30 is detachably connected to the second connecting structure 13 and is abutted against the second piece B to be welded; the second positioning member 30 and the second limiting groove 22 are respectively abutted against two opposite sides of the second to-be-welded member B to fix the position of the second to-be-welded member B, so as to prevent the second to-be-welded member B from displacing relative to the first to-be-welded member a to damage the alignment contact therebetween.
For example, the first connecting structure 11 and the second connecting structure 13 are alignment holes, and then the side of the first positioning member 20 and the second positioning member 30 facing the base 10 may be provided with alignment posts, and the alignment posts are correspondingly inserted into the alignment holes, so as to realize that the first positioning member 20 is detachably connected to the first connecting structure 11 and the second positioning member 30 is detachably connected to the second connecting structure 13.
After the first positioning member 20 is detachably connected to the first connecting structure 11, the first positioning member 20 also limits the first part to be welded a from the side of the first part to be welded a away from the base 10, so as to prevent the first part to be welded a from jumping from the first limiting groove 12 to affect the alignment and welding effect of the second part to be welded B.
The outline shape of the second limiting groove 22 is matched with the outline shape of the second part to be welded B, and one side of the second limiting groove 22 facing the second positioning part 30 is in an open type, so that the second positioning part 30 is detachably connected to the second connecting structure 13, and then the second positioning part 30 is blocked on one side of the second limiting groove 22 and is abutted against the second part to be welded B so as to fix the first part to be welded B.
After the first part to be welded A and the second part to be welded B are welded, the second positioning part B can be detached first, and then the first part to be welded A and the second part to be welded B and the first positioning part A which are welded are detached. Therefore, the first positioning piece 20 and the second positioning piece 30 not only can make the second to-be-welded piece B in aligned contact with the first to-be-welded piece a, but also can facilitate taking and placing the welded second to-be-welded piece B and the first to-be-welded piece a.
