Abstract

Friction welding is a solid state process used mostly for joining dissimilar materials due to mass production with less time consuming. The aim of this work is to study the dissimilar joints of austenitic stainless steel and copper for evaluating the impact strength. The experiment is conducted by using Taguchi’s L9 orthogonal array for determining the value of impact strength. The input parameters such as friction pressure, upset pressure, rotational speed and burn-off length were considered and the optimum process parameter was determined based on the response of impact strength. The predicted value of impact strength was validated by conducting the confirmation run using optimum parameters. The analysis of variance (ANOVA) is conducted for the mean of impact strength.
