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 ().

Method for connecting a sheet metal component, such as a pipe, to a cast metal component, such as a housing port, in particular for an exhaust system

The invention concerns a method and apparatus for production of a hollow section () in which a coiled pre-shape of the hollow section () is deep drawn from a sheet part, which is pre-bent after a trimming process and coiled into the final shape of hollow section (). The edges () of hollow section () lying in the peripheral direction are then joined together in the contact region. In order to improve the joining capability of hollow section () to other components in simple fashion, it is proposed that before the coiling process at least one flat site () for joining to another component be embossed before the coiling process in a pre-bent region of the hollow section ().

Method and device for production of a hollow section

An apparatus and method of attaching an exhaust manifold to an engine's cylinder head utilizing an oversized hole in the manifold, a stud fastener extending through the oversized hole, a spacer element around the stud fastener, and a nut adapted to be tightened to engage the spacer element and the flange wherein a flat gasket is compressed to a desired extent which is not so excessive that it inhibits sliding movement caused by thermal growth of the manifold.
