Abstract
A friction welding method for fastening a connection bushing, such as a threaded bushing for example, in a housing. In order to improve the quality of the connection, the connection bushing is attached to the housing using a friction welding element. The friction welding element consists of the connection bushing, on which a friction welding shell with a radially outer friction welding contour is formed or molded. Connecting and sealing portions are produced between the friction welding element and the housing during the friction welding process by means of a special design of the friction welding contour.
