Abstract: A housing for a component of an exhaust system, in particular for an exhaust gas purification device, has an envelope that comprises a shrunk clamping portion for the component, a transition portion that adjoins the clamping portion in an axial direction, and a connecting portion that adjoins the transition portion in the axial direction. The diameter of the connecting portion is larger than that of the clamping portion. A method of producing the housing for the component includes providing a tubular envelope, and inserting the component into the envelope. A shrinking step is then carried out in the clamping portion which terminates spaced apart from ends of the envelope as viewed in the axial direction, whereas the axial ends of the envelope are not acted upon.

Abstract: A method of producing an exhaust gas-carrying device in which the gas-carrying device includes at least one insert piece and a cylindrical outer housing is disclosed. The method includes the steps of introducing the insert piece into the outer housing and applying radial forces with clamping jaws which bear against the outer surface area of the outer housing and plastically deform the outer housing inwards in order to clamp the insert piece in the outer housing. The clamping jaws are configured to have edges such that marking lines are formed in the outer housing which do not continuously extend axially parallel to the outer housing along that portion of the outer housing in which the insert piece is arranged.

Abstract: A vehicle exhaust gas purification device has a multipart outer housing (10) including a tube (12) and end walls (14) that have been reshaped into funnels. The tube (12) and the end walls (14) are fitted into each other and brazed, soldered or welded to each other.
