A friction welding tool having a main body and a first clamp for gripping a first weld component and a second clamp for gripping a second weld component, at least one of the clamps being movable with respect to the other to effect friction welding of the respective weld components. The friction welding tool includes a vibration damper arrangeable to absorb vibrations of the first weld component during the friction welding. The friction welding tool includes an anchor element arranged to couple the damper to the main body of the friction welding tool to transfer absorbed vibrations to the main body.

Friction welding vibration damping

A weld enclosure and welding apparatus including a weld enclosure. Also a method of welding. The apparatus has first and second opposed tooling faces adapted to receive and hold respective first and second weld elements. The weld enclosure comprises a housing that allows relative movement between the weld elements and a change in a physical dimension of at least one of the weld elements. The weld enclosure also comprises locating means for locating the housing relative to the welding apparatus and includes heating means.
