Abstract
Friction Stir Welding (FSW) is one of the new entrants to the solid state joining technique which have made a remarkable progress in welding technology. It is widely used in automobile and aerospace sectors for the smooth finishing and strength of the materials, there is a wider scope to take up further research in this area. FSW is also a filler-free process, which would considerably lighten the structure. FSW has made realization of high strength aluminium alloy possible. Normally, these alloys are considered non-weldable with conventional welding techniques. The alloys series, for example, are defined non-weldable because they form brittle chemical compounds in the heat affected zone and are characterized by high porosity in the welded metal; these features provides the joint mechanical properties significantly lower than those of the base material. In this paper, we have analyzed the tensile strength of two similar materials of Al-Li alloy, after the FSW welding is performed on two similar aluminium plates adjacent to each other. After completing the welding process, it is finalized that the tensile strength of the material increased after welding is performed also the development of cracks were identified.

Keywords- Friction Stir Welding, similar metals, tensile strength, hardness.
