<p>Apparatus for use in welding a first component (44;55) and a second component (41;75) together by friction welding, comprising drive means (1;1 min ) operative to generate reciprocatory movement, a component holder (10;10 min ) operative to hold said first component (45;55), linking means (4) operative to transmit reciprocatory movement from the drive means (1;1 min ) to the component holder (10;10 min ) so that in operation said first component (55) performs heat-generating movement, pressure means (15;15 min ) operative to exert pressure on the component holder (10;10 min ) so that in operation said first component (45;55) also performs welding movement. The linking means (4) is such as to accommodate that welding movement during friction welding and the pressure means (15;15 min ) is such as to accommodate that heat-generating movement during friction welding. Release means (6,7,8) may be provided to release the component holder (10;10 min ) from the drive means (2,2 min ) to enable the component holder (10,10 min ) to be withdrawn from the welded components.</p> |
