Abstract
Provided are a laser welding method and a laminate with which it is possible to prevent damage to a welded part and improve the quality of a laminate after welding. A laser control unit 12 controls driving of a laser radiation unit 11 so as to cause a first metal sheet W1 and a second metal sheet W2 of a laminate 15 to be irradiated with laser light L in a first state in which the output is adjusted so that fusion is possible. The laser light L in the first state is radiated along a substantially arcuate outer peripheral path OR that extends so as to surround a prescribed portion 15a of the laminate 15 and that has at least a part thereof opened. The laser control unit 12 controls the driving of the laser radiation unit 11 so as to cause the first metal sheet W1, which is the uppermost layer of the laminate 15, to be irradiated with laser light L in a second state in which the output is adjusted so that fusion is conducted without penetrating the first metal sheet W1. The laser light L2 in the second state is radiated in a first path R1 that extends along an inner peripheral portion of the outer peripheral path OR, and also in a second path R2 that extends along the inner peripheral portion of the outer peripheral path OR in the opposite direction from the first path R1.
