The objective of this research to study the impact of v-groove shape on Metal Inert Gas welding procedure of 6mm thickness A6061 aluminum combination and 304 Stainless steel in overlap configuration with welding parameters as; voltage, wire feed rate and shielding gas are 17 volts, 2m/min and 15L/min respectively, the experiment was performed in which the aluminum is upper. 1-mm diameter of ER4042 filler material and pure argon gas as shielded gas. V-groove shapes in steel samples were made with angle 450 . The experiment conducted using SYNERGIC.PRO2 450-4 machine. Tensile test was carried out for each welded sample Universal Testing Machine of MIG welding processes with and without v-grove in steel side. Tensile strengths of welded test samples vary from 15.8 N/mm2 to 26.24 N/mm2 contingents on the welding conditions. The results indicated that v-groove specimens have a maximum strength of tensile strength of 26,24 N / mm2 compared to v-groove samples. It shows the ability to mount inert gas / brazing process aluminum to steel by means of a reversed groove angle and to maximize welding parameters. In conjunction with the half-V-shaped groove the smallest temperature gradient along the steel interface was noted to the smallest difference from top to bottom with IMC thicken values. Tensile test results showed that, owing to its outstanding diffusion behavior of filled filler material, the maximum bonding interface and the correct IMC interface distribution on the steel surface.
