A Friction stir welding is a solid-state joining process in which heat is generated using a third body tool for joining of two surfaces. The objective of the present work is to investigate the effects of various parameters of friction stir welding on the heat generation and to obtain the optimal sets of process parameters so that the heat generation 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 heat generation which is a very important factor for the joining of two metals. The temperature is measured using an infrared thermometer and heat is the direct function of temperature. Also the hardness of the welded surface plays an important role in many applications of the friction welded joint. The hardness is measured using a Vickers Hardness test. 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.
