Fire brigades all over the world use vehicles from Rosenbauer Karlsruhe GmbH & CO. KG. The international technology leader for aerial rescue vehicles fully relies on Carl Cloos Schweisstechnik GmbH for automated welding. Since the middle of 2019, the aerial ladder elements have been welded with two identical QIROX robot systems. The robot is mounted here in overhead position on a linear track with vertical and horizontal stroke. The aerial ladders are inserted between two workpiece positioners, each with a vertically arranged faceplate. The workpiece which is fixed between the faceplates is turned into the optimum processing position by a horizontal turning axis. In addition, the robot systems are equipped with online and offline sensors to compensate for any component tolerances. By changing to the automated welding technology, the company can respond even more flexibly to customer requirements, saves time both in welding and in secondary processes and achieves excellent welding results.
