Abstract
In the current research, an effort was made to study the effect of tool pin profiles using tungsten carbide as the material to decide the weld quality of the friction stir welded AA 6082-T6 thin aluminium alloy. The employed profiles, straight cylindrical, tapered cylindrical, hexagonal, triangular and square, were compared with the joint fabricated with H13 tool steel with the straight cylindrical profile. Tool rotational speed and tool traverse speed were kept constant at 710 rpm and 40 mm/min, respectively. The highest tensile strength of 260.86 MPa was observed for the joint prepared with the hexagonal pin profile due to pulsating action. The highest impact strength of 7 J was observed for the hexagonal tool pin profile. The joint efficiency of the hexagonal pin profile was 83.1% when compared with other pin profiles. The examined outcomes were correlated with the microstructural and fractographic studies.
