The RLW-A remote laser welding system combines optical seam tracking and high dynamic scanners. That enables the usage of difficult 3D geometries with a wide range of joint types. During the robot movement, the RLW-A detects and follows the seam by adjusting the mirror according to the measurement data of the seam tracking. The laser beam and the measurement light are controlled by the same optical system.
An optical seam tracking which is integrated in the welding head recognizes the joint and is positioning the laser focus on the join patch. Due to the high working distance is the head able to pass over spanner and work piece contours. The necessary process time is much reduced in comparison to tactile systems and slightly higher regarding standard laser remote heads.
