Friction welding (FWR) is a solid-state welding and bonding process that generates heat through mechanical friction between workpieces in relative motion to one another. The process is used with the addition of a lateral force called "upset" to plastically displace and fuse the materials. [1]
Vibration welding is often used for larger applications where the parts to be joined have relatively flat seams, although the process can accommodate some out of plane curvature. Recently, the automotive industry has made extensive use of the process to produce parts like manifolds and lighting assemblies whose complex geometries prevent single ...
Successful orbital welding is also dependent upon using high quality tubing material. Typically only 316L stainless steel tubing (not pipe) and fittings are used for automatic orbital GTA welding and are obtained from a number of specialty manufacturers. The weld quality depends upon having a reasonably clean source of Argon for backing and ...
Welding is the joining together of materials ... Orbital welding; ... Rotary friction welding; S. Sciaky, Inc.
Rotary friction welding is widely implemented across the manufacturing sector and has been used for numerous applications, [17] [18] [19] including: Parts in gas turbine such as: turbine shafts, turbine discs, compressor drums, [20]
The oldest welding process in the world. Oxides must be removed by flux or flames. Damascus steel: Friction welding: 42: FRW Thin heat affected zone, oxides disrupted by friction, needs sufficient pressure Aerospace industry, railway, land transport Friction stir welding: 43: FSW A rotating non-consumable tool is traversed along the joint line

Orbital friction welding is NOT similar to spin welding: The workpiece is moving in a small circle WITHOUT rotating. The advantage is the constant and even speed on every point of the welding surface. With spin welding the speed changes with the radius, with linear friction welding the speed is not time constant.
