It should be further noted that, step 3 and step 4 may be performed simultaneously or sequentially, and the order of the two may be replaced with each other; in actual production, since all the material sheets have certain tolerance in size, after four material sheets are positioned and moved through the above steps, a zero gap can be ensured for part of the weld bead, but it cannot be ensured that all the front material sheets 740 can be accurately butted with the left material sheet 720 and the right material sheet 730, that is, a weld bead may exist among the three material sheets, and the weld bead can be welded by adjusting the laser welding machine (such as defocusing the laser, increasing the laser power, slowing the traveling speed and the like) as long as the standard tolerance of the weld bead is controlled within ± 0.15 mm.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
