Already since the 1980ies, Nussbaum has been using CLOOS welding robots. On the occasion of the 75th company anniversary the manufacturer of lifting platforms, situated in Kehl, Baden-Württemberg, modernised its production comprehensively. The target was to increase the productivity and efficiency of the production processes to improve the competitiveness. In 2018, the seven existing welding robots were totally replaced by new robot systems. In total, the welding times could be reduced by about 50 % due to the comprehensive modification, more efficient robots, integration of tacking into the welding process and the reduction of the high variety of parts. They did not only optimise and adapt the robot systems comprehensively but also the logistic and material flow processes to increase the welding production to a maximum.
