A Friction stir welding is also known as solid-state joining process where heat is generated with a third body tool for the joining of two metal surfaces. The main objective of this work is to determine the effects of mentioned parameters used in friction stir welding on the temperature gain or heat generated and to get the various optimal sets of the process parameters so that the response can be optimized. In present work the effects of mentioned process parameters of Friction stir welding such as tool rotation speed, tool feed rate and the tool shoulder diameter have been investigated to find effect on heat generation or temperature gain which is important factor for joining of two metals. Temperature is measured using an infrared thermometer and heat generated is a direct function of temperature. Hardness of the welded surface important role in many applications of the friction welded joint. Using a Vickers Hardness test the hardness is measured. Experiments of present work were designed by using Taguchi methodology. An Orthogonal Array L9 was used and results obtained by the experimentation were analyzed by using MINITAB software analytically as well as graphically.
