Friction Stir Welding (FSW)
SSW process in which a rotating tool is fed along a joint line between two workpieces, generating friction heat and mechanically stirring the metal to form the weld seam
Distinguished from FRW because heat is generated by a separate wear-resistant tool rather than the parts
Applications: butt joints in large aluminum parts in aerospace, automotive, and shipbuilding
