Abstract

The objective of this study was to determine the Tensile-Shear Stress of Friction Stir Welded (FSW) Lap Joints of Aluminium Alloys. FSW lap joints of AA 2014 aluminium alloy plates were performed on a conventional semiautomatic milling machine. Defect free FSW lap joints were produced on alloy plates. Tensile-Shear Stress of FSW lap joints were obtained from the results of shearing tensile tests. New empirical equations were developed for Tensile-Shear Stress based on the relation between the hardness and Tensile-Shear Stress values. Tensile-Shear Stress of FSW lap joints increase exponentially as the hardness reduces.
