Abstract
Friction welding can be used to join different types of ferrous metals and non-ferrous metals that cannot be welded by traditional fusion welding processes. The process parameters such as rotational speed, friction pressure, forging pressure, friction time and forging time play the major roles in determining the strength of the joints. In this investigation, an attempt was made to develop empirical relationships to predict the tensile strength and interface hardness of friction welded dissimilar joints of AIS I304 austenitic stainless steel (ASS) and AA6082 aluminium (Al) alloy using statistical tools such as design of experiments, analysis of variance and regression analysis. The developed empirical relationships can be effectively used to predict tensile strength and interface hardness of friction welded dissimilar joints of ASS-AI at 95% confidence level.
