- Abstract
In this study, effects of the process parameters on the mechanical and micro-structural properties of friction stir welded (FSW) joint of AA6061-T6 have been studied. Welding of aluminium alloy by conventional method is difficult. Therefore friction stir welding which is a solid state welding process, is emerging as a preferred method. After experimentation six samples were prepared at different process parameter i.e. rotational speed of 500, 710 and 1000 rpm along with welding speed of 25 and 40 mm/min. Tensile test and micro-hardness test were conducted on the samples to analyze the mechanical properties. Fractured surface of the tensile samples were also examined with field emission scanning electron microscope (FESEM). Microstructure of FSW joints were analysed with the help of optical microscopy (OM) as well as with FESEM. Different aspects of temperature development during the process were investigated using infrared thermal camera.
