Summary, etc. Many engineering applications are in need of high strength and low weight alloys; titanium and aluminium alloys areused in several engineering applications to reduce weight. In this study, investigate effect of environment conditions onmicrostructure properties of gas tungsten arc welded assisted with brazing of titanium alloy Ti-6Al-4v and aluminium alloyAl7075 has been carried out. Alloys are made joined together in natural environment and at shielded argon gas environmentconditions. Mechanical properties have been arrived, tensile tests have been conducted to examine the strength of weld andresults have been achieved 92.3 Mpa and 356 MPa in regular and argon environment, respectively. Vicker’s hardness valueof 103.4 Hv and 183.1 Hv has been attained in respective environment condition. Fatigue properties have been elevated andfracture surface of the specimens analyzed in respective mechanisms. Welding speed, arc voltage and welding currentparameters are considered to join the dissimilar alloys in both environments and identified the most influencing parameters.SEM and XRD techniques have been used to weigh up the microstructures of weld interface. The outcomes confirmed thatargon gas, as a joining environment, has a substantial blow on properties of mechanical and microstructure of the weld joint.
