The use of a double sided friction stir welding tool (known as a bobbin tool) has the advantage of giving a processed zone in the workpiece which is more or less rectangular in cross section, as opposed the triangular zone which is more typically found when conventional friction stir welding tool designs are used. In addition, the net axial force on the workpiece is almost zero, which has significant beneficial implications in machine design and cost. However, the response of these tools in generating fine microstructures in the nugget area has not been established. The paper presents detailed metallographic analyses of microstructures produced in 25mm AA6082-T6 aluminium wrought alloy, and examines grain size, texture and mechanical properties as a function of processing parameters and tool design, and offers comparison with data from welds made with conventional tools.

At the ambient temperature, in the 0.2 M NaHSO3 and 0.6 M NaCl solution, by gravimetric test, potentiodynamic polarization curve test and electrochemical impedance spectra (EIS), the electrochemical behavior of 5083/6082 friction stir welding dissimilar weld and two parent materials were comparatively investigated. The results indicated: at the given processing parameters, the anti-corrosion ability of the dissimilar weld was superior to those of the 6082 and 5083 parent materials.

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.
