Abstract (en)
[origin: FR2752180A1] In a welding process two pieces placed end to end along an assembly joint to be welded with laser beam, the joint is continuously observed, by means of a camera (47) integral with the welding head (43), by moving together the welding head (43) and the camera (47) along the joint, the position of the joint for each position of the welding head (43) and camera (47) assembly along the joint is sensed, the impact of the welding beam is continuously observed, and its position is controlled to the sensed position of the joint, by displacing the welding head (43) and camera (47) assembly mutually perpendicular to the joint.
