Gas Tungsten Arc Welding, Factorial Design Approach, Weld Deposit Area


Gas Tungsten Arc Welding (GTAW) is a commonly used welding process that produces an arc between a non-consumable electrode and the work to be welded. This experimental study aims at optimizing various Gas Tungsten Arc welding parameters including welding voltage (V), welding current (I), gas flow rate (GFR), nozzle to plate distance (NPD) and Torch angle (Ó¨) by developing a mathematical model for sound weld deposit volume of a SS303 specimen. Factorial design approach has been useful for discovery the relationship between various process parameters, weld deposit volume and the hardness of the welded area. The study revealed that the welding voltage, current and gas flow rate varies directly with weld deposit volume and inverse relationship is found between torch angle and NPD with weld deposit Area.
