Abstract:
1. A laser welding method comprising: providing a robot that is moveably in accordance with predetermined movement data, and that includes a laser beam emitting section; measuring a current movement position of the robot with respect to a movement position specified in the predetermined movement data; operating of the robot to change the current movement position of the robot to a prescribed position based on the predetermined movement data; and adjusting a laser emission direction by controlling an emission changing section of the laser beam emitting section based on the current movement position of the robot that was measured and the predetermined movement data such that a laser beam is emitted from the laser beam emitting section and strikes a predetermined irradiation position of a workpiece; and controlling the laser beam emitting section to emit the laser beam onto the predetermined irradiation position of the workpiece to conduct welding.
