    摘要： A steering wheel armature includes a hub, a spoke and a rim. The hub has a first portion and a second portion. The second portion is attached to a steering column. The spoke is attached to the first portion of the hub via friction welding. The rim is friction welded to the spoke to interconnect the rim and the first portion of the hub, wherein the first portion is stir friction welded to the second portion such that the rim is attached to the steering column.

    摘要： A method of fabricating a rack, the method includes: supporting a first rack bar having a first toothed part on a shaft of the first rack bar; supporting a second rack bar having a second toothed part on a shaft of the second rack bar such that an axial center line of the second rack bar coincides with an axial center line of the first rack bar; supporting a joint member between the first and second rack bars such that an axial center line of the joint member coincides with the axial center lines of the first and second rack bars; rotating the joint member about the axial center lines of the first and second rack bars relative to the first and second rack bars; and bringing an end of the first rack bar and an end of the second rack bar into friction pressure welding with the joint member.

    摘要： A method for joining materials such as metal alloys that includes a first component, wherein the first component includes a first alloy having a known austenization temperature below which martensite forms when the component is heated and then cooled at a predetermined rate of cooling; a second component, wherein the second component includes a second alloy; and a welding apparatus operative to create a weld between the first and second components without crossing the austenization temperature of the first alloy. The method also includes the steps of validating the characteristics of the weld created between the first and second components in real-time during the welding process; modifying the welding apparatus to prepare the surface of the first component prior to welding to assure proper alignment of the first and second components; and/or physically modifying the second component to enhance the welding characteristics and durability thereof.

    摘要： A friction welding apparatus has first and second clamps for respectively holding first and second parts to be welded by rotary friction welding, a device for producing relative rotation between the first and second clamps and a forge for applying an axial forging pressure to the parts to be welded when the parts are located in the clamps. The second clamp is mounted on a first half of a coupling. A second half of the coupling is movable axially between first and second positions. In the first position the second half of the coupling is engaged with the first half to prevent rotation of the second clamp and enable relative rotation between the first and second clamps. In the second position the second half of the coupling is disengaged from the first half to enable rotation of the second clamp and stop relative rotation between the first and second clamps.

    摘要： A method of operating a linear friction welding apparatus includes holding a first work piece with a first fixture, holding a second work piece with a second fixture, pressing the first work piece toward the second work piece along a press axis with a press assembly, establishing a selective load between the first work piece and the second work piece with the press assembly while the first fixture and the second fixture are in a fixed position relative to one another, and simultaneously vibrating, with a vibrating assembly spaced apart from the press axis, the first fixture and the second fixture along a single weld axis so that both the first work piece and the second work piece are moved with respect to one another along the single weld axis after establishing the selective load.

    摘要： A method is provided of replacing a damaged blade of an integrally bladed rotor assembly including a disc and a plurality of blades extending outwardly from a rim of the disc. The method includes the steps of: removing the damaged blade to leave a blade repair stub projecting from the rim; locating sacrificial supports at the underside of the rim beneath the repair stub, the supports projecting axially beyond the trailing and leading edges of the rim; depositing metal around the trailing and leading edges of the repair stub, the deposited metal, supported by the sacrificial supports, projecting axially beyond the trailing and leading edges of the rim; attaching a replacement blade to the repair stub by linear friction welding; and removing excess deposited metal, upset metal from the linear friction welding, and the sacrificial supports.
