摘要

Sheared steel sheet materials (12, 14) are abutted against each other with burrs (20, 22) of the steel sheet materials (12, 14) directed in the same direction. A laser beam (30) is irradiated onto the abutment portion of the assembly of the steel sheets from the sagging side of the assembly. At the same time, a filler (28) in the form of a wire is supplied to the abutment portion from the same side as the laser beam irradiation. The steel sheet materials (12, 14) are joined together to form a press material (10). Then, the press material (10) is set in a press machine (48) in a direction that a surface of the press material (10) opposite to the laser beam irradiated surface, faces the exterior when stamped and mounted to a vehicle. Then, the press material (10) is stamped and is formed into a vehicle panel.
