Effect of Welding Parameters on Mechanical and Microstructural Properties of Dissimilar Aluminum Alloy Joints Produced by Friction Stir Welding

Abstract:

The effect of processing parameters on the mechanical and microstructural properties of dissimilar AA6061 t6–AA5083 0 joints produced by friction stir welding was studied. Different samples were produced by varying the advancing speeds of the tool as 20 and 40 mm/min and by varying the alloy positioned on the advancing side of the tool. In the various trials the rotating speed is varied from 600 to 900 RPM. All the welds were produced perpendicular to the rolling direction for both the alloys. Micro hardness (HV) and tensile tests performed at room temperature were used to evaluate the mechanical properties of the joints. Various tests were performed on the joints previously subjected to ageing. In order to analyze the micro structural evolution of the material, the welds’ zones were observed optically.
