摘要：
A welding target is irradiated with a laser beam so as to form a beam spot that moves relatively with respect to the welding target along a locus having a spiral shape rotating around a rotation center moving in a welding direction. The welding target is welded using the laser beam irradiated with. While the welding target is irradiated with the laser beam, the welding target is irradiated with the laser beam based on an interval coefficient which is a value indicating an overlapping degree of the locus having the spiral shape in the welding direction.
