ABSTRACT:
Friction welding tooling includes a cassette (2,4) for holding a component (6) which is to be welded with great accuracy to a clamped workpiece. The cassette is carried on the distal end of an oscillator arm (8) and urged against the workpiece surface so the cassette has to transmit the frictional heating and weld forming forces to the component. The component (6) must be clamped accurately and securely by the cassette for accurate welding. The cassette comprises a base portion (2) and a floating cap (4). The base portion carried by the oscillator arm (8) has locating features (15,16) to position the component (6) accurately. The floating cap (4) has similar locating features (13,16) but locates entirely on the component (6). The cap (4) is then securely clamped to the base portion (2) with a force transmitting wedge (22) inserted by opposing faces (24,25) in a load path.
