摘要： A laser welding system includes a robot control unit that acquires movement amount measurement values from encoders provided on axes of the robot and calculates the current position of a laser processing head based on the measurement values. Based on the calculated current position of the laser processing head, the robot control unit calculates a laser beam emission direction specifying the direction in which the laser beam should be aimed in order to strike a predetermined laser irradiation position. The robot control unit sends a command indicative of the laser beam emission direction to a processing head control unit which changes the direction of a reflecting mirror provided inside the laser processing head such that the laser beam is emitted in the specified direction.

摘要： 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.
