Description
Summary:The current study deals with a different type of tool design by considering the process parameters. The process parameters here are the speed of the welding process, offset of tool pin, and axial load plunge all these helped in obtaining the dissimilar material. In this proposed research the dissimilar materials Cu-Copper (6061) and AL-Aluminium (T651) for the process of Friction Stir Welding (FSW) joints. To evaluate the performance certain experimental procedures have been done including the micro and the macrostructure, hardness test, tensile test, electron-dispersive tests, and scattered electron microscopy test. Through which the welding property and weldability of the dissimilar material Cu and AL will be evaluated. With the help of the cylindrical tool pin defect-free, dissimilar FSW can be achieved. The highest TS of about 132 MPa and Hardness performance of 180 HV has been achieved in the FSW through the help of process parameters. The tool pin was plaCced at 1450 rpm, 30 millimeters per minute at two-degree, 2mm. The load value of the Axial plunge was completely dependent on the diameter and the tilt angle. The load range of Axial plunge ranges from 550 to 600 Kg which helped in achieving defect-free Cu to AL (6061-T651) with 6.5 millimeters in thickness at FSW joints.
