The aim of present study was to analyze the influence of the microstructures and mechanical properties of friction stir welded joint of 6082 aluminium alloy and copper plates in 3 mm thickness with using filler materials. With this aim, welds were produced using High molybdenum high speed steel, with a cylindrical pin tool having 3 mm and 14 mm diameter of pin and shoulder respectively. The microstructures of weld were studied by optical microscopy and grain size in TMAZ, HAZ and NZ were analyzed. Vicker’s microhardness tests were done in transverse direction of weld to check the hardness distribution in HAZ, TMAZ and weld nugget. Transverse tensile test were performed to evaluate the weakest portion of weld joints.
