Friction welding is a solid state joining process the joints are formed by utilizing the heat generated by friction. This paper discusses the importance of impact toughness in friction welded components and the effect of various process parameters on impact toughness. The process parameters considered in this research work are friction force, Forge force, rotational speed and burn-off length for the 15CDV6 alloy steel and the Impact toughness is optimized to establish the weld quality using the Taguchi experimental design technique with an orthogonal array of L9, ANOVA. The effects of process parameters are discussed in detail based on the values obtained in the ANOVA and micro structural observations.
