An effort has been made to summarise most of the aspects of FSW (friction stir welding) process and the effect of process parameters of this welding technique on mechanical as well as microstructural behaviour of aluminium alloys. The variations in the process parameters discussed in this review paper are: variation of the downward force, variation of the probe angle, length of probe, shape of shoulder, rotational speed of the tool, pin profile, traverse speed and working conditions. The setups used in majority of places consist of vertical milling machines. It has been observed that the joint strength is increased between the dissimilar materials on introducing a third foil of roughly one-tenth thickness, between the two sheets of dissimilar material to be joined, in case of lap joint. The value of thermal co-efficient of expansion for the filler metal sheet must lie between the values of the thermal expansion coefficients of the materials of the sheets to be joined.
