The friction stir welding is new method of joining processes used recently in many engineering industry. The objective of the present work is to investigate the effects of the various parameters of friction stir welding on the impact strength and to obtain the optimal sets of process parameters so that the impact strength can be optimized. In this work the effects of various process parameters of Friction stir welding like rotation speed of tool, feed rate and the shoulder diameter have been investigated to find their effect on impact strength of Aluminium 6063..Morever the impact strength was calculated using a Charpy V-notch test on Impact Testing Machine. Test method of IS: 1757:1988 is used for investigation at temperature of 40c. The experiments were designed by Taguchi methodology. L9 Orthogonal Array was used and Results of the experimentation were analyzed by MINITAB software analytically as well as graphically.
