Abstract (en)

[origin: WO2005080045A1] Disclosed is a method for joining a sheet metal part (3) to a cast metal part (5). According to the inventive method, the sheet metal part (3) and the other part (5) are welded together in a pulsed welding process. Said method particularly allows a sheet metal pipe (3) to be welded to the port (12) of a cast metal housing (13). Said advantage can be used for an exhaust system comprising an exhaust manifold (3) and an exhaust unit such as a turbocharger (5).
