ABSTRACT FRICTION WELDING 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') operative to generate reciprocatory movement, a component holder (10;10') operative to hold said first component (45;55), linking means (4) operative to transmit reciprocatory movement from the drive means (1;1') to the component holder (10;10') so that in operation said first component (55) performs heat-generating movement, pressure means (15;15') operative to exert pressure on the component holder (10;10') 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') 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to release the component holder (10;10') from the drive means (2,2') to enable the component holder (10,10') to be withdrawn from the welded components.
