Definition

A solid‑state joining process in which a rotating, non‑consumable tool with a profiled shoulder and probe is traversed along a joint under pressure; frictional heat and severe plastic deformation produce localized softening and dynamic recrystallization that consolidate the abutting materials into a continuous solid bond without melting.
