Abstract (en)

[origin: EP2338633A1] The friction welding process comprises pressing a workpiece to be mounted on a component under rotation against the component, and partially melting or plasticizing the workpiece and the component on point of contact so that a tight connection is held after cooling. The power that is compressed with the workpiece and the component is increased at the end of the welding process in impact-like and temporary manner. An independent claim is included for a friction stir welding device.
