Abstract Aluminium and its alloys have been used in automotive technology since the first model of the car. The need for aluminium material is getting increased for weight reduction, improved fuel economy and vehicle performance. The amount of the aluminium used in a car is mainly related with joining processes of aluminium alloy. This can be achieved by developing the welding techniques for aluminium alloys. The purpose of this study was to determine the effects of friction stir spot welding parameters on tensile shear strength of friction stir spot welded lap joint EN AW 5005 Aluminium alloy. The variable parameters were tool rotation (rpm), dwell time (s) and the tool pin height (mm). Tensile shear test results indicated that the weld performance was significantly affected by the tool rotation, dwell time and the tool pin height. The results of the study indicates that there are optimum process parameters which give the highest tensile shear strength.

FSW has become the most effective technology in solving problems that have reached the profiled sheets with the continuation of material, particularly in the aerospace industry, with the use of different joining techniques that require high ductility and tensile strength. Current study, FS weldments AA6061-T6 were successfully obtained with varying processing parameters and were mechanically and metallurgically characterized. This paper illustrates macrostructure analysis, influence of tool geometry and process parameters, Fractography analysis microstructure analysis, microhardness of aluminium alloy AA6061-T6.
