Friction stir welding(FSW)is a solid-phase welding operated under the melting point of workpiece materials;it's a technology which uses an anti-friction tool to join the sheet or shaped materials in rotary circs,and can be used in the welding of aluminum,magnesium and copper and has good welding quality.Generally,intensity of welds in FSW exceeds heat affected zone.This paper also introduces the application of FSW in shipbuilding and shipping manufacture,and research requirement in shipping manufacture.
