Description
Aluminium alloy A6N01-T5 (Al, 0.63%Mg, 0.53%Si) hollow extrusions suitable for joining by friction stir welding, to be used in the generation of Japanese railway rolling stock, were designed, and the static and fatigue tensile strength of joints were measured. Finite element methods were used to design an extrusion able to withstand the stresses associated with friction stir welding. Butt joints in plate were welded and the hardness distribution across the weld, the ultimate tensile strength, the yield strength, the elongation and the fatigue strength were determined and compared with typical values for MIG welded joints. Application of the results to joints in extrusions is discussed.
