ABSTRACT: Friction stir welding (FSW), a solid-state
welding and inertial welding, the FSW process is
joining technique, is being extensively used in similar as well as similar joining of Al, Cu,Ti,and their alloys. In the present study friction stir welding of two aluminium alloys AA7075 and AA2014 were carried out at various combinations of tool rotation speeds and feed and axial force.. In this experimental proper selection of input friction welding parameters necessary in order to control weld distortion and subsequently increase the productivity of the process. In order to obtain a good quality weld and control weld distortion, it is therefore, necessary to control the input welding parameters. In this research work, experiments were carried out on AA 7075 and AA2014 of 6 mm thick using friction stir welding process with constant tool with various parameters like that RPM, Feed and Axial Load. Experimentally analyzedcylindrical tool was used and compare to each other parameter and investigate which one parameter gives more higher tensile strength and other properties, and found the effect of FSW process parameters on mechanical properties of friction stir weld of aluminum alloys 7075 and 2014using constant profile. From the macro investigation the second test plate found good with the parameter 900 RPM 18 mm/min tool traverse and the axial force is 7 KN obtained the best parameter during the Friction welding processes.
unique in that it enables theadvantages of solid-state joining for fabrication of continuous linear welds, the most common form ofweld joint configurations that are predominately made by the arc welding processes in today industry. The specially designed tool has twoessential parts. The first part is the profiled pin extending along the rotating axis. The second part isthe shoulder. Rotating at high angular speeds, the pin plunges into the work piece until the shouldermakes full contact with work piece surfaces. The rotating tool then moves along the jointline with theshoulder fully in contact with the work piece surface under a relatively high axial forging
