A Review on Optimizing Process Parameters for TIG Welding using Taguchi Method & Grey Relational Analysis
Imran A. Shaikh | M. Veerabhadra Rao [2]
Abstract: Gas tungsten arc welding (GTAW) or Tungsten inert gas welding (TIG) is one of the widely used techniques for joining ferrous and non-ferrous metal. Gas tungsten arc welding process, consist of non-consumable tungsten electrode which is used to provide the arc for welding. During the welding cycle a shield of inert gas expels the air from the welding area and prevents oxidation of the electrode, weld puddle and surrounding heat-affected zone. For joints where additionally weld metal is needed, a filler rod is fed into the puddle. In the present review paper an attempt is made to understand the effect of TIG welding parameter, that are influences on responsive output parameters such as tensile strength of welding, distortion due to welding by using optimization method. Welding parameters such as welding current, gas flow rate, root gap, bevel angle are main parameter which is mostly used.
