Abstract
In present work friction stir welds (FSW) of 3 mm thick AA 6063-T4 aluminium alloy were prepared at different speeds and feeds. The welding parameters were considered in order to achieve non-defective welds. The welds produced were classified as ‘‘hot welds” and ‘‘cold welds”. The cold welds, obtained with the minimum tool rotational speed and maximum traverse speed. Cold welds have improved mechanical properties relative to the hot welds that were in under match condition relative to the base material. The tensile strength and hardness properties are found by experiments at three different speeds and feeds. The results are analysed
