Friction stir welding (FSW) is a relatively new, solid-state, metal joining process invented by Wayne Thomas et al. at the Welding Institute of England (now TWI) in 1991 [1.] A FSW butt weld is made by following the joint-line of two butted pieces of material with a rotating tool while applying a significant down-force through the tool. Heating is provided at or near the tool-work interface by the rotating tool, traditionally a single piece comprised of a shoulder, which contacts the material… CONTINUE READING
