Abstract

Friction stir spot welding (FSSW) is a solid state welding process; and it is used to overcome the difficulties of joining aluminium and copper alloys. Dissimilar joining of AA1060 and C11000 using friction stir welding was carried out. The microhardness profile analyses were carried out and the probability distribution function (PDF) of the measured microhardness values was determined. Additionally, shear tensile tests were conducted. High microhardness values were obtained in the region close to the keyhole of most of the samples, which could be linked to the presence of intermetallic compounds in the stir zone of the spot welds. For the shear tensile test, only a nugget pull out failure mode took place in all the produced spot welds. The PDF revealed that the process parameters and the tool geometries significantly have an effect on the distribution of the microhardness values.
