Abstract
A laser welding method includes a welding step of applying a laser beam to a surface of a workpiece while the laser beam is caused to advance in an X-direction and scanning with the laser beam is simultaneously performed in a Y-direction intersecting the X-direction. The welding step includes a first weaving step of causing the laser beam to weave in the Y-direction with first amplitude (A), and a second weaving step of causing the laser beam to weave with a predetermined amplitude smaller than first amplitude (A) at both end portions of a weaving trajectory drawn by the laser beam in the first weaving step.
