Friction Stir Welding is a solid state joining technique which is widely being used for aerospace, marine, automotive and other applications for joining similar and dissimilar metals. Compared to other welding techniques FSW produces better mechanical properties in the weld zone. The main objective of this article is similar joints of AA8011 alloy mechanical behaviour was investigated with process parameters such as tool angle,tool rotation speed & welding speed in detail. Three major factors at three levels namely tool angle, rotational speed and weld speed are considered for the present study. The uncontrollable factors include ultimate tensile strength, percentage of elongation which can be converted to signal-to noise ratios, by using Taguchi method which is a multiple response process used to optimize the factors. The ultimate tensile strength and percentage of elongation values for different combinations are noted from the response table and we get the optimum rank for the process parameters. Hence the prediction of the optimum process parameters using Taguchi technique is investigated.
