-Abstract
The joining of two different aluminum alloys AA5052- AA6061 plates thickness 6mm is carried out by
Friction Stir Welding (FSW) technique. . Input parameters are spindle speed (1000 to 1400 rpm), feed rate (10 to 20
mm/min) and tool profile. By varying the process parameters, defect free and high efficiency welded joints were
produced. Optimum process parameters were obtained for joints using statistical approach. Three different tool
designs have been employed to analyses the influence of rotation speed and traverse speed over the hardness and
tensile properties. Effect of welding speed on hardness distribution and tensile properties of the welded joints were
investigated. Hardness studies revealed that the lowest hardness in the weldment occurred in the heat-affected zones
whereas tensile failures were observed to take place.
