<p>Holding means for a component in a friction welding operation consists of a hollow cassette which is open at one end. The component is inserted into the cassette and an aperture at the open end is shaped to frictionally engage a thickened portion of the component with a force greater than forces transmitted to the component during a friction welding operation. The component is pressed into the cassette to a predetermined depth so that a portion remains protruding and forms the weld interface. Material upset during the welding operation may be sheared by increasing the weld generating force to overcome the frictional holding force so the end face passes over the weld region. <IMAGE></p> |
