The system consists of two stations and a 7-axis QRC-E 350 robot. The robot is mounted on a floor track and can move flexibly back and forth between the two stations. Due to its long reach, it can be easily guided around corners or into niches. The rotary and swivel positioner always moves the complex workpiece into an optimum position for welding. The large component - here a base frame for a processing machine - is welded using the Speed Weld process. Thanks to the directionally stable and powerful arc, comparatively high welding speeds with deep penetration can be achieved with Speed Weld.
