Abstract

DC60 (26/07/42) in laser beam welding method. Of welding workpiece along circular arc welding while laser beam welding machine Is driven in relative motion with the workpiece, the laser beam output is controlled to change with the relative movement speed in the weld area. Where time is slower compared to Movement speed at the beginning of welding and at the point End of welding Or similar, so the penetration depth is consistent This occurs over the entire length of the weld in the laser welding method.

1. Laser beam welding method Of laser welding operations along the weld line Of the workpiece in a relationship The relative motion between the workpiece and the laser beam welding machine at a constant speed is defined as a characteristic that when a change in relative motion speed occurs. Between the workpiece as Said and the beam welding machine The laser beam then the output of the laser beam is controlled to change in a ready Relative to the change in the movement speed:
