Abstract:

The parameter optimization on friction stir welding of aluminum alloy for the better mechanical properties has been studied. Taguchi’s orthogonal array concept is used to run the experiments to find the optimal parameter setup. The strength of the welding is depending on the correct combination of the influencing parameters. If wrong combination is selected, the quality is also affected. The objective of this project is to maximize the mechanical properties like tensile strength and hardness of the welded zone. The process parameters such as tool rotational speed (rpm), welding speed (mm/min), dwell time (minutes), and tool tilt angle (degree) play important role in friction stir welding. Totally nine experiments are conducted based on L9 orthogonal array and the hardness is measured on the welded zone.
