Abstract

In the present study, AA5052 is Friction stir welded with 6082 to find out the effect of process parameters on the hardness of the joint. The welding is performed on 5mm thick plates with one side single pass of H13 HSS tool. Parameters used in experiment are tool rotation speed(1200, 1950 & 3080rpm), welding speed(40, 50, 60mm/min.) and tool tilt angle(0, 1, 2°) with different combinations. Hardness test were performed on the 9 combination suggested by Taguchi method (miniTAB 17). The results shows that the maximum hardness was found on 1950 tool rotation speed, 50mm/min traverse speed and 2° tilt angle. The experiment also suggested that with increases in tool rotation speed and traverse speed, the hardness increase to a maximum level then decrease. The hardness found lower then both parent material.

Keywords: FSW, Aluminium Alloy 5052 & 6082, Hardness.
