Abstract: A method for welding together pieces which form a curved or angled end product using a friction welding process is described. The method comprises; providing first and second pieces which together define the end product geometry, each piece comprising an end product geometry portion and a sacrificial weld portion, the sacrificial weld portion forming a dog-leg relative to the end product geometry portion and terminating in a planar weld interface surface. The pieces are arranged with their planar weld interface surfaces together at a weld surface interface and the sacrificial weld portions in coaxial alignment. Mechanical friction is applied between the planar weld interface surfaces sufficient to plasticly deform the sacrificial weld portions. An axial force is applied along the co-axis of the sacrificial weld portions sufficient to upset the sacrificial weld portions and bring together the end product geometry portions. The sacrificial geometry portions are removed to provide the end product.

Abstract: For butt-welding, which includes bringing joining end surfaces (50 and 51) of a cup member (12a) and a shaft member (13a) into abutment against each other and radiating a high energy intensity beam from a radially outer side, the shaft member (13a) has a recess (52 or 53) on a radially inner side of the joining end surface (51) to obtain a welded portion (49) having a closed hollow cavity on a radially inner side after butt-welding. The joining end surface (50) (protruding surface (50a)) of the cup member (12a) protrudes toward a radially inner side with respect to an inner diameter (E) of the joining end surface (51) of the shaft member (13a). With this, a welded portion (74) of an outer joint member (11) of a constant velocity universal joint (10), which is manufactured by joining the cup member (12a) and the shaft member (13a), can be improved in strength and quality.

Abstract: An apparatus and method for protecting an inner radial surface of a housing of a turbomachine from corrosion. The method includes tapering the inner radial surface of the housing and a corresponding outer radial surface of a corrosion-resistant liner, and heating the housing to increase a diameter of the inner radial surface of the housing. The method also includes inserting the corrosion-resistant liner at least partially into the housing, and attaching the corrosion-resistant liner to the inner radial surface of the housing a solid-state bonding process.
