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.

Welding tool comprising a shoulder, welding method and workpiece

A welding tool for connecting at least two workpieces at a connection region by friction stir welding includes a shoulder that separates the connection region from the surroundings. The shoulder is designed as a molding tool to mold during the friction stir welding.

A welding tool for joining at least two workpieces at a joining region by friction stir welding includes a tool pin arranged along one axis of the welding tool, for applying frictional heat to the workpieces. The welding tool also includes a shoulder surrounding the tool pin, for separating the joining region from the surrounding area. The shoulder is moveable essentially parallel to the axis of the welding tool.

An exhaust gas treatment device has a housing and a hollow body through which exhaust gas flows and which is accommodated in the housing. The hollow body consists at least partly of a gas permeable substrate. The hollow body is connected at least one end to a wall member arranged in the housing and formed to be flexible in the axial direction.

A static mixing element, in particular for arrangement in an exhaust system of an internal combustion engine, has a grid-like component having a flow therethrough. The grid-like component is formed in one piece from an elongated metal strip. In the production of the static mixing element, the metal strip is bent to form the grid-like component.

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.

Housing for a component of an exhaust system and method of producing such a housing

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