“Efficient Tandem MIG Welding of Bogie Longitudinal Girders for Rail Vehiclesâ€-Case Study

Abstract

Welding - ELH Eissenbahn Lautwerke GmbH & Co. KG Halle, a well known medium-sized company, supplies bogies to wagon manufacturers for both the domestic and export markets. The longitudinal girders, which are more than 3 metres long and are made of 16mm thick steel plates, are welded on a robot system supplied by Carl Cloos Schweisstechnik GmbH, Haiger Germany. The Tandem high capacity welding process, where two welding wires are melted simultaneously, enables both improved seam quality and considerably higher weld speeds to be achieved.
