— Friction welded joints are formed in the solid state by the heat generated by friction. As the technologicaladvancements take place on daily bases the advancements in automobiles are not out of the race. Any form of boosting forengine power leads to increased temperatures and pressures in the combustion chamber, and much higher exhaust gastemperatures. The exhaust valve, which already has much higher temperatures to deal with than the inlet valve in a naturallyaspirated engine, will see its temperature increase still further. So bi-metal valves made of Inconel 718 and SS 304 are underdevelopment. Exhaust valves are required to be very precise. They are produced by friction welding. The objective of thefollowing study is to study the effects of the parameters on the on the burn-off of friction welded Taper Inconel 718 and SS304 for production of Bi-metal Poppet Exhaust Valve. The study here discuses the use of Design of Experiments by TaguchiMethod. Here Orthogonal Array of L27 is used. Using multiple linear Regression and ANOVA effects on the burn-off ofwelding by Welding Parameters (Rotational Speed, Friction Pressure and Time) are analyzed using MINITAB 17.
