  • Patent number: 10183356
    Abstract: A welding method for connecting at least two workpieces at a connection region by means of friction stir welding using a welding tool having a probe and a shoulder. The method includes rotating the probe around a rotation axis, wherein the connection region is softened by friction heat provided by the probe during said friction stir welding to form a welded seam at the connection region. The method also includes molding, simultaneously with forming the welded seam, at least one of a bevel, a rounding and a chamfer on an edge of the connection region using the shoulder, wherein the shoulder is configured to separate the connection region from the surroundings.
    Type: Grant

  • Patent number: 8092748
    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.
