Friction stir welding of dissimilar AA6063/Al joint

The dissimilar joint between aluminium alloy 6063 and aluminium has been made using the friction stir welding process. Three input parameters: Tool rotational speed, feed rate and dwell time have been varied and their effect of the mechanical properties has been studied. Obtained weld joints have been characterized for tensile properties, hardness, and corrosion behavior. Effort has been made to study the in process force acting on the joint and establishing its dependence on the welding parameter. The use of full factorial design methodology brings out the contribution of input parameters and their effect on the output mechanical properties.
