The present disclosure includes a laser welding method in which a joint surface between a plurality of workpiece members is welded by radiating laser beam LB, and a locus of laser beam LB is controlled so as to perform wobbling scanning Sw by a combination of scanning motion Sa moving along first direction x parallel to the joint surface and swing motion Sb including first swing component Bx along first direction x and second swing component By along second direction y perpendicular to first direction x, the method including a defect determination step of determining occurrence of a welding defect; and an output control step of increasing or decreasing an output of laser beam LB when laser beam LB is radiated again toward the welding defect in a case where the welding defect occurs.
A laser welding method of welding a joint surface between a plurality of workpiece members, the method comprising:
A laser welding apparatus comprising:
