SSI Schäfer has put a high-performance CLOOS robot welding system into operation for its complex welding assemblies. Equipped with a welding torch changing system, the QRC360E robot uses two welding processes. In addition to the high-performance Tandem Weld welding process, the robot uses the Speed Weld pulse welding process. An extended special welding torch and the eccentric axis integrated into the robot mechanics give the robot system the necessary range and flexibility to weld the complex component optimally.
