		In continuous drive friction welding, welding heat is obtained at the joint by rotating one part against the other at a constant or varied RPM, with an axial force applied to the mating components.
		A satisfactory solid-phase weld requires that metallic bonds be established between the atoms at the surfaces of the metals to be joined.
		When welding medium or high carbon steels, for example, it would normally be expected that in addition to changes in grain size and shape the high cooling rates common to all welding processes would create the transformation products often indicated by the representative TTT curve.

	Welding - Wikipedia, the free encyclopedia
		Welding, however, was transformed during the 19th century—in 1800, Sir Humphrey Davy discovered the electric arc, and advances in arc welding continued with the inventions of metal electrodes by a Russian, Nikolai Slavyanov, and an American, C.L. Coffin in the late 1800s, even as carbon arc welding, which used a carbon electrode, gained popularity.
		Shielded metal arc welding was developed during the 1950s, using a consumable electrode and a carbon dioxide atmosphere as a shielding gas, and it quickly became the most popular metal arc welding process.
		Welding in space is also possible—it was first attempted in 1969 by Russian cosmonauts, when they performed experiments to test shielded metal arc welding, plasma arc welding, and electron beam welding in a depressurized environment.

		Generally, the former method is selected when friction welding components for high duty applications, because it is necessary to ensure that at least a minimum loss of length occurs between the components to be joined.
		Friction welding produces a joint which is at least equal to 100% of the area of the smaller of the two parts being joined.
		The friction welding machine uses hydraulic cylinders to move the head, open and close the chuck, open and close clamps, apply brake, etc. The hydraulic control valves and pumps are usually designed to operate the machine at pressures lower than 2000 psig.

		That friction is used to generate enough heat to allow both components to reach a plastic state where the materials are forced together to form a bond.
		Friction welding can be used to create cast or forge-like blanks that reduce the higher costs incurred by tooling and minimum quantity requirements.
		By friction welding the more durable stainless steel ends onto the metal tube shaft, the life expectancy of the part was extended by eight times.

	Plastics joining - Friction welding techniques
		Friction welding refers to a range of techniques that rely on a relative motion between the thermoplastic parts to be joined, while a force is applied between them, to cause the material at the interface to heat and melt.
		Orbital welding is a relatively new technique, and tends to fill the size gap between benchtop ultrasonic units and linear vibration welders, and most applications tend to be for automotive components.
		The angular friction welding process is used for circular components where upper and lower component alignment is critical, and equipment tends to be bespoke.

	Friction Stir Welding (Site not responding. Last check: 2007-10-26)
		The friction heating generated at the interface softens both components, and when they become plasticised the interface material is extruded out of the edges of the joint so that clean material from each component is left along the original interface.
		Friction stir welding has been used to weld all wrought aluminium alloys, across the 2xxx, 5xxx, 6xxx and 7xxx series of alloys, some of which are bordering on being classed as virtually unweldable by fusion welding techniques.
		Friction stir welding has also been used to weld lightweight panels made of plastic foam sandwiched between two sheets of aluminium, for which any fusion welding technique would encounter serious problems because of the much higher temperatures involved.

	Friction Stir Welding at TWI
		Consistent with the more conventional methods of friction welding, which have been practised since the early 1950s, the weld is made in the solid phase, that is no melting.
		In friction stir welding (FSW) a cylindrical, shouldered tool with a profiled probe is rotated and slowly plunged into the joint line between two pieces of sheet or plate material, which are butted together.
		Frictional heat is generated between the wear resistant welding tool and the material of the workpieces.

	Friction Stir Welding
		The heat is generated primarily by friction between a rotating--translating tool, the shoulder of which rubs against the workpiece.
		The welding parameters have to be adjusted so that the ratio of frictional to volumetric deformation--induced heating decreases as the workpiece becomes thicker.
		The microstructure of a friction-stir weld depends in detail on the tool design, the rotation and translation speeds, the applied pressure and the characteristics of the material being joined.

	Inertia Friction Welding
		Inertia Friction Welding is a variation of friction welding in which the energy required to make the weld is supplied primarily by the stored rotational kinetic energy of the welding machine.
		In Inertia Welding, one of the work pieces is connected to a flywheel and the other is restrained from rotating.
		The kinetic energy stored in the rotating flywheel is dissipated as heat through friction at the weld interface as the flywheel speed decreases.
