Experimental Study on T-Joint of Friction Stir Welding on AA 1065 Aluminum Alloy
Rajankumar Belani,  T.Prabakaran
Friction stir welding (FSW) is a solid state joining process for joining high conductivity materials like aluminum and its alloys. T-joint at various parameters were produced by the friction stir welding. Some parameter provides defect free joints while the other parameters show defects. The tool pin is used in all the parameter is helical shaped. In the present study T-joints of AA 1065 aluminum alloy is made without defects. Experimentation will be carried out by changing principle parameters of FSW process. Macro and micro images of traverse section of the weld were captured and analyzed to identify the defects and the bead geometry values were found out using macro images. Most of the defects occur at advancing side at top side of the weld joint. The liquid penetrant inspection (LPI) test was performed for all the joints and no surface cracks were formed on weld line. Scanning electron microscopy (SEM) with Energy dispersive X-ray spectroscopy (EDS) spectra was taken at various weld zones, which shows the topography of welded zone and oxides formation. Tensile properties and micro hardness of the joints were experimentally evaluated for joints formed at different process parameters.
