Laser beam welding device with radiation trap |
摘要 |
A device for making metal tubing comprises a tube forming device for shaping a continuously conveyed metal band into an open seam tube and a welding device for welding the longitudinal seam of the tube. The welding device is a laser welding device with a welding head which is inclined at an angle with respect to the vertical. Disposed after the laser welding head is a radiation trap for trapping reflected laser beams. The radiation trap (3) is composed of a metallic housing with water-cooled walls and an inner surface which is blackened. The radiation trap (3) is arranged relative to the laser welding head (1) in such a way that the reflected laser beams (1b) are guided into the inside of the housing.
