Friction stir welding has the advantage that many of the welding parameters, eg. tool design, rotation speed and travelling speed, can be contralled in a precise manner, thus controlling the energy input into the system. Therefore, the micro-structure of the welding aluminium were tested, the residual stresses induced by the friction stir welding process conducted with 500rpm and 100mm/min was also measured. The stresses in the test specimen peaked at -9Mpa and had the conventional "M" profile.
