Literature review on friction stir welding of magnesium alloys

Friction stir welding is a new solid-state joining process which is used to join the soft material. It is using a specially designed tool that rotates and traverses along the joint line, creating frictional heating that softens a column of material underneath the tool. The softened material flows around the tool through extensive plastic deformation and is consolidated behind the tool to form a solid state continuous joint. The friction stir welding of magnesium alloys and composite material has many engineering applications in industries such as marine, railway, aerospace, Shipbuilding, land transportation. In this review article the basic principle of friction stir welding and several aspects of friction stir welding, effects of varying welding parameter of Magnesium alloy is referred and discussed.
