The Heun group has trusted in the CLOOS welding technology for decades. This QIROX robot welds circular welds for tank containers using the precise and clean TIG process. Due to the change from manual to automated welding, the company is now able to produce higher quantities within a shorter time. In the past, it took 25 minutes to weld the tank containers manually. Today the robot only needs 12 minutes to weld the same component using the TIG weld process. Apart from the quicker welding time and the reduced production costs the component quality could be further increased due to the exactly reproducible welding results.
