The purpose of the current work is to investigate the combined effect of thickness and the mechanical properties of dissimilar aluminum alloys annealed AA6061-O and heat-treated AA7075-T6 on the tensile strength of the joint. The joint is made by Tungsten Inert Gas (TIG) welding using suitable fillers Al 4047 and Al 5356. Different samples i.e. Welded Over-Nugget Sample (WOS), Welded Ground Sample (WGS) and Base Material (BM) were investigated under tensile loading. In order to avoid failure, the thickness of weak strength AA6061-O must be greater as compared to the thickness of AA7075 comprising high strength in order to balance stresses on both sides. In addition to, the effect of grounded and as-welded bead on the joint properties of the weld is explained in this research. The joint is also characterized by microstructural attributes using electron microscopy and the grain size is observed as well. [ABSTRACT FROM AUTHOR] |
