The system consists of two stations and a 7-axis robot, model QRC-E 350. The robot is fixed to a floor-mounted linear track and can travel back and forth flexibly between the two stations. The reach of the robot means that it can be easily guided around corners or into niches. The turn/tilt positioner always positions the complex workpiece perfectly for welding. The big component - here a base frame for a machine tool – is welded with the Speed Weld process. The directionally stable and powerful Speed Weld arc allows comparatively high welding speeds at deep penetration.
