Effect of process parameters on residual stress in AA1050 friction stir welds

In the current work, aluminum AA1050 plates has been successfully joined using friction stir welding (FSW) technique. The effect of processing parameters such as tool rotation speed and travel speed on the mechanical properties are investigated. Residual stress has been carried out using the destructive cutting length method; the results found that common stresses are compressive type, which are formed due to friction stir welding process. The results revealed that welding travel speed has a remarkable influence on the resultant residual stress.
