Influence Of Process Parameters On Aluminium Alloy 5083 In Pulsed Gas Tungsten Arc Welding

Abstract-Welding is a permanent joining process used to join different materials like metals, alloys or plastics, together at their contacting surfaces by application of heat and or pressure. During welding the work piece to be joined are melted at Among all the welding processes, the chief advantages in using Gas Tungsten arc welding (GTAW) for surfacing are high reliability, all position capability, ease of use, low cost and high productivity. Due to high strength, good welding properties, increased wear and corrosion resistance and high strength-to weight ratio, Aluminium 5083 is widely used in Ship building, Rail cars, Vehicle bodies, Tip truck bodies, Pressure vessels. In this study, Pulse TIG welding parameter’s on weldability of 5083 alloy specifications. The welding parameters such as welding current, Gas flow rate, and different filler diameters are taken into account which influences the properties of material at welded area. Aluminium 5083 sheets were welded by Pulse Tig welding with 5356. The effect of welding process parameters is analyzed by conducting of micro hardness, and Impact tests on weld joint. Key wards: AA 5083, Pulsed TIG welding, Gas Flow rate, Welding Current, Micro hardness and Impact test properties.
