Abstract

Aluminium alloy was a predominant metal among alloys elements. The aluminum alloys like Al7075 and Al6061 which has the major elements of Zn, Mg, Cu, Si with which it will improve the hard-brittle crystalline structure and conductivity. To enhance the properties of dissimilar joint metal, TIG (Tungsten Inert Gas) welding is propagated. Mechanical properties like Tensile, Impact, Bending, micro-hardness and the study about microstructure analysis were carried out. As a result, the energy absorbed by the dissimilar joint metal is 16J and the hardness of dissimilar joint metal is 51.3HV.It revealed that, there is a high impact strength and micro-hardness properties. Consequently, the microstructure (HAZ) image exhibits good bonding strength and sufficient plastic deformation was improved due to fine distribution of grains.
