FSW (Friction Stir Welding)
“FSW: The high-strength joining technology that needs no bolts or rivets.” FSW (Friction Stir Welding) is a solid-state joining method developed in 1991 at The Welding Institute (TWI) in the UK. Unlike conventional fusion welding, FSW joins materials without melting them. The process involves inserting a rotating tool into the joint line. The frictional heat
