The Experimental Analysis of Friction Stir Welding on Aluminium Composites

This research is to study the influence of friction stir welding on the microstructure and hardness of aluminium 6035 and 8011. The parameters which influence the friction welding are rotational speed of 550 rpm and welding speed of 40-90 mm/min. As a result of the experiment it had been found that maximum tensile strength is 50 N/mm2 for welding speed of 60 mm/min. The hardness test results showed the maximum obtainable hardness as 91 HV at weld center. The microstructure test results showed that the high tensile strength and hardness is obtained in the friction stir welded zone of aluminium 8011.
