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 cover plate - is welded using the VariWeld process. With Vari Weld, an extremely low-spatter pulsed arc is generated, which reduces time-consuming reworking to a minimum. Due to the comparatively low temperature, the base material remains metallurgically unaffected and the corrosion protection of the surface is retained.
