In friction stir processing (FSP), a rotating tool is used with a pin and a shoulder to a single piece of material to make specific property enhancement, such as improving the material's toughness or flexibility, in a specific area in the micro-structure of the material via fine grain of a second material with properties that improve the first.(Ma) [6] Friction between the tool and workpieces ...
Dissimilar friction stir welding (DFSW) is the application of friction stir welding (FSW), invented in The Welding Institute (TWI) in 1991, [1] to join different base metals including aluminum, copper, steel, titanium, magnesium and other materials. [2] It is based on solid state welding that means there is no melting.

Friction stir welding (FSW) is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material.
Forge welding (FOW), also called fire welding, is a solid-state welding process [1] that joins two pieces of metal by heating them to a high temperature and then hammering them together. [2] It may also consist of heating and forcing the metals together with presses or other means, creating enough pressure to cause plastic deformation at the ...
The process is used with the addition of a lateral force called "upset" to plastically displace and fuse the materials. [1] Friction welding is a solid-state welding technique similar to forge welding. Instead of a fusion welding process, Friction welding is used with metals and thermoplastics in a wide variety of aviation and automotive ...
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]
Friction extrusion is a thermo-mechanical process that can be used to form fully consolidated wire, rods, tubes, or other non-circular metal shapes directly from a variety of precursor charges including metal powder, flake, machining waste (chips or swarf) or solid billet.
