giving a high standard of control and accuracy. Friction welding is clean, dry, hydraulically activated and PLC controlled and requires neither flux nor special atmosphere.
Friction welding is effective where at least one of the components is circular at the weld face, i.e. tube to tube , bar to bar, tube to bar and tube or bar to flat surface. The process is used to weld most grades of steel and, in addition, has the proven ability to join widely different combinations of non-ferrous materials such as copper to aluminium, copper to steel, stainless steel to aluminium, etc.
Since the friction welding process produces full face homogeneous joints, it is accepted as an extremely reliable production aid. Friction welding the subject of a range of international standards including BSEN ISO 15620:2000and is widely used in the Automobile, Nuclear, Aerospace, Electrical, Chemical, Cryogenic and Marine industries.
Friction welding is particularly suitable for reducing the costs of complex forgings or castings, e.g. welding of spindle or shaft to cast or forged head.
