Beschreibung
Zusammenfassung:	This welding method for welding a workpiece that, for example, includes a first member and a second member overlapping the first member in a first direction and comprising a different material than the first member, said welding being carried out by irradiating a surface with laser light, said surface being located on an end portion in the opposite direction from the first direction, and thereby welding the first member and the second member, wherein a welded portion that includes welded metal stretching from the surface and through the first member in the first direction to the second member is formed in the workpiece, and when the thickness of the first member in the first direction is defined as T1, the penetration depth Wd of the welded metal in the first direction is T1
