Abstract

Friction welded joints are formed in the solid state by the heat generated by friction. As the technological advancements take place on daily bases the advancements in automobiles are not out of the race. Any form of boosting for engine power leads to increased temperatures and pressures in the combustion chamber, and much higher exhaust gas temperatures. The exhaust valve, which already has much higher temperatures to deal with than the inlet valve in a naturally aspirated engine, will see its temperature increase still further. So bi-metal valves made of Inconel 718 and SS 304 are under development. Exhaust valves are required to be very precise. They are produced by friction welding. The objective of the following study is to study the effects of the parameters on the Tensile strength of friction welded taper Inconel 718 and flat SS 304 for production of Bi-metal Valve. The study here discuses the use of Design of Experiments by Taguchi Method. Here Orthogonal Array of L27 is used. Using ANOVA effects on the Ultimate Tensile strenght of welding by Welding Parameters (Rotational Speed, Friction Pressure and Time) are analyzed using MINITAB 17.
