Abstract

Tungsten Inert Gas (TIG) welding is welding process of joining different materials with high quality weld bead by electric arc generation between non consumable electrode and work piece under a shielding gas. It is used to weld ferrous and non-ferrous metals. It is also known as Gas Tungsten Arc Welding (GTAW) process. This process imply several advantages like low heat effected zone, joining of unlike metals, absence of slag, high heat concentration etc compared to other welding process. The TIG welding parameters are the most important factors affecting the quality, productivity and cost of welding. Plenty of the problems that are obstructing to achieve good weld quality can be avoided by proper consideration of the particular characteristics and requirements of the process. TIG Welding performance is mostly evaluated based on Tensile Strength of the weld, Weld bead Geometry, Hardness, Depth of Penetration and Width–to-Depth ratio Also known as Aspect ratio. In the present study, we discuss the influence of the different welding parameters such as welding speed, power source, type of current, shielding gas flow rate, electrodes, filer wire, Electrode gap and types of shielding gases which fits best to determine arc stability, arc penetration and defect free welds. Various approaches are proposed in the literature to achieve the solution related with optimization of these parameters. This has been carried out by doing literature survey on the effective point of view which helps to compare their main features and to choose the most suitable approach for a specified application.
