Plasma arc welding (PAW) uses non consumable tungsten electrode and arc is formed between electrode and workpiece. Shielding gas can be separated from plasma arc by placing the electrode within the body of the torch. Among different welding processes, plasma welding has various advantages like non-contact, high welding quality, narrow heat-affected zone, deep penetration etc which makes it superior to the commonly used processes. Plasma welding has broad range of applications in different engineering field. This present research work provides an overview of the effects of plasma arc welding and its various parameters on different materials. The heat transfer during plasma arc welding to the work piece has significant effect upon the weld material quality. This research work also reviews the heat transfer modeling of plasma arc welding that had been developed by researchers for prediction of better weld geometry and weld quality.
