ABSTRACT:
Sheared steel sheet materials are abutted against each other with burrs of the steel sheet materials directed in the same direction. A laser beam 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 wire is supplied to the abutment portion from the same side as the laser beam irradiation. The steel sheet materials are joined together to form a press material. Then, the press material is set in a press machine in a direction that a surface of the press material opposite to the laser beam irradiated surface, faces the exterior when stamped and mounted to a vehicle. Then, the press material is stamped and is formed into a vehicle panel.
