Objectives: This paper presents the influence of vibratory Tungsten inert gas welding on the hardness of aluminum 5052- H32 alloy weldments are studied. Methods/Statistical Analysis: Hardness of Al5052-H32 is analyzed for different voltage inputs keeping other parameters like welding current, welding speed and gas flow rate constant. Findings: Hardness values are compared for the specimens prepared with vibrations and without vibrations. Hardness of Al5052-H32 specimens prepared at 160 V input voltage is more compared to the specimens prepared at 70 V, 230 V and without vibration. There is a decrease of hardness value is observed for specimens prepared at 230 V compared to the specimens prepared at without any vibrations.
