The device comprises a connecting frame, a welding gun, and a cutting mechanism, the welding gun is fixed on the connecting frame, and the cutting mechanism is connected to the connecting frame. The meshing structures are disposed on welded plates, and after being assembled, the two plates can be restrained by the meshing structures in multiple dimensions. Before welding, edges of the plates are cut according to the form of the meshing structures, then the plates are assembled and meshed; after the position of the welding gun is adjusted, the cutting mechanism and the welding gun are driven by a welding robot or a special welding machine to move along a weld; and the meshing structures are removed by the cutting mechanism, and then normal welding is performed by the welding gun.
