Friction welding, FRW, solid state welding

Описание: Friction welding is a solid state bonding process that produces high integrity, full contact joints. By rotating one work piece relative to another, whilst under a compressive axle force, the friction generated between the two faying surfaces produces heat, causing the interface material to plasticise. The compressive forge force displaces the plasticised material, extruding interface material and any contaminants, promoting molecular bonding, creating a homogeneous bond between the parent materials. With friction welding, no third-party filler materials, flux or shielding gases are required. The process is machine controlled, 100% repeatable, with full in-process monitoring and quality assured.
Friction welding FRW is a solid-state `welding process that generates heat through mechanical friction between workpieces in relative motion to one another, with the addition of a lateral force called "upset" to plastically displace and fuse the materials. Because no melting occurs, friction welding is not a fusion welding process, but a solid-state welding technique more like forge welding. Friction welding is used with metals and thermoplastics in a wide variety of aviation and automotive applications.
ISO norm of friction welding is EN ISO 15620:2019 there is information about basic terms and definitions and table of weldability of metals and alloys.
