Beschreibung
Zusammenfassung:	A method welds together two components of an internal combustion engine exhaust system, by resistance welding, to provide greater positioning freedom of two components welded together. A first component is provided with a welding area including an insertion opening edge surrounding an insertion opening. A second component is provided with a welding area including an insertion area to be inserted into the insertion opening. The insertion area is inserted into the insertion opening such that the insertion area is in contact with the first the entire insertion opening edge. An electrical voltage is applied to resistance weld the first component to the second component. The surface (28) of the insertion area is curved about two axes that are not parallel or is curved about an axis that is parallel to the surface of the insertion area, or/and an insertion surface of the insertion opening edge is located in one plane.
