BS EN ISO 15620:2019,Welding – Friction welding of metallic materials.BS EN ISO 15620:2019 pdf free download here.
Friction welding is a method for making welds in the solid phase in which one component is moved relative to and in pressure contact with the mating component to produce heat at the faying surfaces. The weld being completed by the application of a force during or after the cessation of relative motion There are several forms of supplying energy and various forms of relative movements.
The generation of friction heating results in a comparatively low joining temperature at the interface. This is largely the reason why friction welding is suitable for materials and material combinations which are otherwise difficult to weld, The weld region is generally narrow and normally has a refined microstructure.
While the friction welding process deals primarily with components of circular cross-section it does not preclude the joining of other component shapes.
BS EN ISO 15620:2019 specifies requirements for the friction welding of components manufactured from metals.
It specifies requirements particular to rotational friction welding related to welding knowledge, quality requirements, welding procedure specification, welding procedure approval and welding personnel.
BS EN ISO 15620:2019 is appropriate where a contract, an application standard or a regulatory requirement requires the demonstration of the manufacturer’s capability to produce welded constructions of a specified quality. It has been prepared in a comprehensive manner to be used as a reference in contracts. The requirements given can be adopted in full or some can be deleted, if not relevant to the construction concerned.
