The steel specialist voestalpine welds drive axle bridges for commercial vehicles at its Linz site using an interlinked robot system from CLOOS. The complex system consists of a total of four welding stations and seven robots. The axle bridges are transported from station to station fully automatically via a shuttle system. At the second station, two QIROX QRC 350 robots weld the cover layers to both sides of the axle bridges. First, the robots weld the cover layers to one side of the axle beam. Then the workpiece positioner with counter bearing rotates the axle beam by 180° to weld the cover layers on the other side. After these work steps, the shuttle system transports the finished welded axle beam fully automatically to the next production station.
