Abstract: This investigation represents the effects of parameters of friction stir welding on tensile strength and hardness during welding of Aluminium Alloy 6105. A fabricated FSWM set up was used for welding. A high carbon steel tool having 18 mm shoulder diameter and 5.5 mm pin diameter has been used. It was noted that for the friction stir welding of aluminium alloy 6105, maximum tensile strength is 0.0912 KN/mm2 , which is obtain at 1250 rpm tool rotation speed, 25 mm/min welding speed and 00 tilt angle. It was also noted that the maximum vicker hardness is 65.7 which is obtain at 1550 rpm rotational speed, 35 mm/min welding speed and 0.50 tilt angle.
