Short answer: Friction welding joins parts by rubbing them together under force until the interface plasticises from heat, then forging the softened surfaces into a solid-state bond with no filler, flux or melt — producing a clean, full-strength joint with minimal heat-affected zone. Spin friction welding joins round parts end-to-end, upset (linear) friction welding joins bars and non-round sections, and radial friction welding attaches collars or flanges to tube; all are favoured for dissimilar-metal joints and high-integrity shafts where fusion welding would dilute or crack.
