The invention relates to a bearing housing body group () of an exhaust-gas turbocharger, having a housing () for a bearing arrangement of a rotor shaft (); having a turbine wheel () on one end () of the rotor shaft (); having a compressor wheel () on the opposite end () of the rotor shaft (); and having a compressor-wheel-side housing cover () which can be fixed by means of a fastening device () in a compressor-wheel-side housing opening (), wherein the fastening device () is designed as a bayonet connection.

Bearing housing body group of an exhaust-gas turbocharger

In the method according to the invention for connecting a sheet metal component () to a component () consisting of cast metal, the sheet metal component () and the component () are welded to one another by means of a pulse-welding method. In particular, a sheet metal pipe () can thereby be welded to the port () of a housing () consisting of cast metal. This advantage may be utilized for an exhaust system with an exhaust manifold () and an exhaust assembly, such as a turbocharger ().
