Friction stir welding is a welding method without welding filler material,low heat input and small welding deformation,great joint mechanical performances. The method has played an important role in aerospace,ship,automobile,rail transportation and electronics industry. In the field of friction stir welding of aluminum alloy,the introduction and transformation of international advanced standards and the development of national standards will make the actual production process and management process more specific,more standardized and more operable,which has an important significance. In this paper,the standard applicable ranges,friction stir welding process specifications,aluminum alloy friction stir welding quality and testing requirements are analyzed between national and international standards. The national standards are interpreted. The paper has played an important guiding significance on the actual welding productions and processes.
