Abstract

The joining of dissimilar material is most essential nowadays due to its increasing in a wide range of industrial applications. Friction welding is a solid state joining process, has a great potentials in welding of dissimilar materials due to its environmental friendliness and less time consuming. The main aim of this paper is to study the dissimilar material joints of austenitic stainless steel and copper which finds application in cryogenic fluids, power generation industries and reactor cooling systems. The dissimilar joints are produced by varying friction pressure, upset pressure, rotational speed and burn-off length to determine its influence on impact strength of the weld joint. The weld interface shows high impact toughness under high upset pressure and rotational speed with low friction pressure with the combination of parameter. The impact failure of joints was examined under scanning electron microscopy (SEM) and type of failure modes is discussed.
