Abstract:
1. A laser welding system comprising: a robot configured and arranged to move in accordance with predetermined movement data; a laser beam emitting section mounted to the robot and configured and arranged to emit a laser beam, the laser beam emitting section including an emission direction changing section configured and arranged to redirect the laser beam emitted from the laser beam emitting section; a measuring section configured and arranged to measure a current movement position of the robot with respect to a movement position specified in the predetermined movement data; and a control unit configured to move a movement position of the robot to a prescribed position based on the predetermined movement data, and to control the emission direction changing section to adjust a laser emission direction in which the laser beam is emitted from the laser beam emitting section based on the current movement position of the robot and the predetermined movement data such that the laser beam strikes a predetermined irradiation position.
