Special features of copper such as high electrical and thermal conductivities, favorable combinations of strength and ductility, and excellent resistance to corrosion have made it an acceptable material for use in many industrial areas. Due to unique performances characteristic Joining of Copper materials find applications in many sectors including Nuclear, Electrical, and Electronics industries. The copper and copper alloys can be joined by most of the commonly used methods such as gas welding, arc welding, resistance welding, brazing and soldering, but fusion welding of copper is difficult because of its high thermal diffusivity and high oxidation rate at melting temperature, one of the ways to overcome these problems is friction stir welding (FSW). FSW is a solid state welding process in which a non-consumable welding tool is used to generate the frictional heat between the tool and the work piece in order to make a solid state joint. Mechanical property of friction stir welding join of copper is good as compare to the other conventional welding process. Conventional welding process is also decrease the thermal and electrical conductivity of copper at weld joint this difficulty is also overcome by FSW, because of the many advantages of FSW process is prove that the FSW is suitable for the copper and its alloy. In this paper we try to explain the effect of friction stir welding on mechanical property and microstructure at weld joint.
