Abstract
A laser welding apparatus and method reproduces a welding state substantially identical to an actual operation of a robot at a manufacturing site even when an operating speed of the robot is changed. When a moving speed of the robot is, for example, 50% of an override ratio, a welding point speed, which is a resultant speed of a focus moving speed of the laser beam by movement of the robot having a scanner head and the focus moving speed of the laser beam by rotation of the laser scanning mirror, becomes identical to that when an override ratio is 100%. This is achieved by increasing a rotating speed of a laser scanning mirror within the scanner head.
