Abstract
A method of forming a plug-like member comprises placing a consumable member (4) in a bore (1) of a workpiece (2). The consumable member (4) is rotated relative to the workpiece (2) while they are urged together so as to generate frictional heat and the formation of plasticised material (5). The plasticised material (5) is allowed to solidify so as to form a plug-like member having an outer surface conforming to the inner surface of at least part of the bore (1). The plug-like member is either left in situ or, following formation of the complete plug-like member, removed from the workpiece.
