As a contract manufacturer for international market leaders in various industries, Bieber Industrie has relied on welding technology from CLOOS for more than 20 years. The latest system from 2019 now welds the complete grate trough for waste incineration systems. The QIROX QRC-350 robot is mounted here in overhead position on a linear track with vertical and horizontal stroke. The workpiece positioners bring the component into the perfect position for welding. It has a horizontal swivelling axis with an L-shaped extension arm. The extension arm contains a vertical rotary axis with a faceplate which serves for holding the workpiece. The robot is fitted with a torch changing system. This allows the use of different welding processes – depending on the application. In addition, the robot system is equipped with an arc sensor to compensate for any component tolerances.
