Friction stir welding results in low distortion and high joint strength compared with other welding procedures, and is able to join all aluminium alloys that are not considered as virtually weldable with classical liquid state techniques. The comparative study on high cycle fatigue properties between A16005-T6 friction stir welds and MIG weld joints have been performed and fracture mechanisms for the fatigue specimens were investigated. Although mechanical properties are lower than the corresponding base material, FSW joints of A16005-T6 become higher at tensile and fatigue strength in comparison with the traditional fusion weld(MIG). The fracture surfaces of FSW and MIG fatigue specimens cleary show different aspects of the fracture morphology. MIG weldments were characterized by voids and cleavage(brittle fracture) but FSW specimens showed the presence of ductile fracture surface.

Friction stir welding is a relatively new solid state joining process. A6061-T6 and A5052-H32 aluminium alloy has gathered wide acceptance in the fabrication of light weight structures requiring a high strength to weight ratio and good corrosion resistance. This friction stir process uses a non-consumable tool to generate frictional heat in the abutting surfaces. The welding parameters such as tool rotational speed, welding speed, etc., and tool pin profile play a major role in deciding FSP zone formation in A6061-T6 and A5052-H32 aluminium alloy. Three different tool pin profiles have been used to fabricate the dissimilar butt joints. The formation of friction stir processed zone has been analysed macroscopically. Tensile properties of the joints have been evaluated and correlated with the friction stir processed zone formation.
