In the present work, the mechanical behaviour of base metal, friction stir welded (FSW) sheet and only weld zone of FSW sheet has investigated and evaluated the properties namely flow strength, elongation and hardness. The experimental data was compared with simulation results for individual tensile behaviour of all the three sheets. Micro-hardness showed a decreasing trend, from the base material to the centre of the nugget zone, except near the transition zone. The FSW sheets showed a decreased flow stress and improved elongation when compared to base material.

Keywords: Friction stir welding; tensile properties; elongation; hardness; prediction.
