Abstract

A study was made on welding of 4mm thick aluminum alloy 5083 plates using friction stir welding. The table of experiments was prepared based on abilities of universal milling machine. The experiments were conducted atdifferent tool rotations speeds of 900r/min, 1120r/min, 1400r/min and 1800r/min. The welding speed is opted as 20mm/min. Examination was made with the cylindrical taper profile tool. Samples for microstructure analysis, Rockwell hardness measurements and tensile test samples were prepared. It is detected that the better mechanical properties were achieved at moderate tool rotational speed, and equi-axed grains obtained at threaded profile tool, grain size were obtained half of the base material.
