| dc.description.abstract | In the present experimental work, friction stir butt welding of thick AA1350 grade Aluminium plates has been taken as basis of research work. As the previous published work shows research work upto 6-7 mm thicknesses, plate thickness of 12.7mm ( above 10mm) was selected for our research work. The three welding parameters- spindle rotation, welding speed and tool tilt angle were considered as input parameters and FSW was performed on 12.7 mm thick AA1350 Grade Aluminium plates. Using Taguchi L9 orthogonal array methodology , the experiments were planned and conducted. Tensile strength, Electrical conductivity and hardness measured on test samples were chosen as output response factors. After doing the trial runs on Universal Milling Machine, three different workable settings for selected parameters were obtained and optimum levels of setting and process variance were achieved by Taguchi method. The confirmatory experiments were later conducted to validate the optimum parameters setting and the results were compared. SEM analysis was performed on good as well as bad samples and defect analysis was done. From the results, it was concluded that: 1) Maximum Tensile strength was found at welding speed of 80mm/min, Tool rotation of 900 rpm and Tool tilt angle of 2⁰. 2) Maximum nugget hardness was found at welding speed of 125mm/min, tool rotation of 560rpm and tool tilt angle of 0⁰. 3) Maximum electrical conductivity was found at welding speed of 125mm/min, tool rotation of 560rpm and tool tilt angle of 0⁰. | en_US |
