Abstract
In traditional joining process, copper alloys are hard to weld owing to its thermal and electrical properties. Owing to the high melting temperature and large thermal conductivity, excessive heat is needed for the joining operation of copper alloys. With Increased heat input, the heat affected region of the welded part increases, the mechanical and thermal properties of the component deteriorate. The objectives of this research are to discover the ideal mechanical performance of FSW of copper alloys. Two main factors such as tool speed and traversing speed has been investigated. A cylindrical profile of tool pin is used for all the experiments. A total of four experiments were conducted with two rotational as well as traversing speed for this investigation. The response such as tensile strength was analysed for accessing the integrity of the welded joints. At a steady load, the joints manufactured are found to have a highest tensile strength of 262 Mpa. Thus the 93.57 percentage of joint efficiency is achieved.
