Description

Friction stir welding of aluminium alloy JIS-6N01-T5 (Al, 0.4-0.8%Mg, 0.4-0.9%Si) was investigated for subway [underground railway] rolling stock applications by comparing the welded joint properties with those of MIG and laser welded joints. Sheet of 4 mm thickness was welded, and the influence of welding speed:rotational speed ratio (0.05-0.36), joint gap and joint tracking errors was evaluated by measuring the tensile and fatigue strength of the joints. Distortion was minimised by optimising the clamping and cooling, and the surface of the weld enhanced by backing plate modifications.
