This article is about an innovative welding system for the fully mechanized production of large dimensioned tubular nodes which are designed as welding constructions. The system is characterized by its flexibility regarding to the weight of the components as well as the type of installation. First, the main assemblies of the robot welding system and their essential components are described. Problems concerning the welding process as a consequence of the design concept are presented. Additionally, solution approaches to these problems are discussed on the basis of experimental results. Finally, a description of potential process steps within the production of tubular nodes, which also could be implemented by the use of the described manipulator, is given.
