Abstract: Friction welding (FW) is a process of solid state joining which is extensively used in present scenario due to most economical, high productive, ease of manufacture and environment friendliness. Friction welding can be used to join different types of Ferrous, Non Ferrous metals and its combinations that cannot be welded by traditional fusion welding process. It is widely used in aerospace and automotive industrial applications. This process employs a machine which converts mechanical energy into heat at the joint to weld using relative movement between work pieces without external heat energy. The process parameters such as Rotational speed, Friction pressure, Friction time, Forge Pressure play major role in determining the high tensile strength of the weld for alloyed material i.e. Cu Zn28 Pb2.Taguchi Method is applied for optimizing the welding parameters to attain maximum tensile strength of the joint and microstructure of the welded joint, base material and heat affected zone is studied with good structure without any defects.
