Abstract
This study investigates the mechanical and microscopic characteristics of the friction stir welded AA5083/AA6082 dissimilar joint. The welding process was performed at a rotational speed of 900 rpm, traverse speed of 60 mm min−1, and a tool tilt angle of 1°. Samples were extracted from the joint’s start, middle, and end positions in both the traverse and longitudinal directions. The analysis of these samples involved various tests, including microstructural analysis, bending, and tensile tests. The microstructural analysis revealed non-linear behaviour in both the longitudinal and traverse sampling directions along the joint. Specifically, there were notable differences in the microstructure between the different locations within the joint. In terms of mechanical properties, the ultimate tensile strength results of the traverse specimens were found to be higher compared to the specimens sampled longitudinally. This suggests that the joint’s strength may vary depending on the sampling direction. On the other hand, the flexural strength results showed a contrasting pattern, with the traverse specimens exhibiting lower strength values compared to the longitudinally sampled specimens.
