摘要： A laser welding method for stacked workpieces. A laser irradiation diameter that is irradiated on a surface of one workpiece among two stacked workpieces is set such that a laser irradiation diameter at a weld ending-edge portion is equal to or greater than approximately 1.5 times a laser irradiation diameter at a weld starting-edge portion. Thus, at the weld ending-edge portion, the material is melted in a wider area compared to a conventional example, and therefore, the melted material is supplied to the center portion of the weld ending-edge portion while the weld ending-edge portion is solidifying. As a result, a depth of the recess at the weld ending-edge portion can be made shallow enough to guarantee the welding quality of each of the workpieces.
