ABSTRACT:
Metal sheets having different thicknesses are abutted to define an abutment line and then are laser-welded. During laser welding, the laser beam is directed to a line (a weld line) which is apart from the abutment line on a thicker sheet side. The distance between the abutment line and the weld line is preferably in the range of 0.1 mm to 0.4 mm. Preferably, the laser beam weaves from side to side with respect to the weld line. As a result, a sharp edge is removed from the thicker sheet and a smooth transient surface is formed on the weld bead. The resulting one-piece sheet can be used as a press material without any pre-pressing processing, such as grinding.
