STUDY ON EFFECT OF TOOL GEOMETRY ON ENERGY AND TEMPERATURE OF FRICTION STIR WELDING

This paper proposes a mathematical model using five different tool designs to analyze the influences of rotation speed and welding speed on the energy generation and peak temperature. Furthermore, the results obtained from mathematical modeling show that the peak temperature and energy per unit length produced during welding using cylindrical pin profile, while the triangular pin profile has the lowest temperature among all pin profile under the given working conditions. The generated energy and peak temperature models developed analytically and solved by developing a computer program in C++ language. Paper deals with reduction of time and cost of calculating the effective energy and peak temperature of the developed mathematical equations
