Abstract
A subsea friction welding apparatus comprises a chuck for supporting and retaining a weld item prior to welding the weld item to a work-piece, said chuck comprises a plurality of jaws having an internal profile to grip a corresponding profiled surface on the weld item and means for radially expanding the internal profile of the jaws of the chuck, said means actuable by axial insertion of the weld item into the chuck thereby avoiding relative rotation of the chuck and the weld item during insertion of the weld item into the chuck. In operation of the method, a supply of weld items and a weld head are deployed to a subsea location and the weld items are loaded via ROV into the weld head at the subsea location.
