<p><P>PROBLEM TO BE SOLVED: To provide a laser welding apparatus capable of reproducing the 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. <P>SOLUTION: When a moving speed of the robot (a robot speed) is set to an override 50% (the speed indicated by a solid line is changed to the speed indicated by a dotted line in the figure), a welding point speed, which is a resultant speed of the robot speed and a focus moving speed, becomes identical to that when the override is 100% by increasing the focus moving speed of the laser beam for moving the laser focal position by turning a reflecting mirror in a scanner 6. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
