However, this does not welding and TIG welding techniques using work piece ensure that the selected welding process parameters can material AISI 1020 OR C20 low carbon steel. Where inputs produce the optimal or near optimal weld pool geometry for parameters for MAG-CO2 welding are welding current, that particular welding machine and environment. Design optimization of Process Parameters for TIG 1 Tungsten inert gas (TIG) welding is an arc welding process that produces coalescence of metals by heating them with an arc between a non-consumable electrode and the base metal (Kumar and Sundarrajan, 2009). TIG welding offers several advantages i.e. joining of dissimilar metals, low heat affected zone, absence of slag etc.

Tungsten Inert Gas welding is a fusion welding process having very wide industrial applicability. In the present study, an attempt has been made to optimize the input process variables (electrode diameter, shielding gas, gas flow rate, welding current and groove angle) that affect the output responses i.e. hardness and tensile strength at weld centre of the weld metal SS202.
joints [Fig. 1] were fabricated by double pass on one side for TIG welding process. The process is performed using the AA 4043 filler rod of diameter 1.6 mm and using argon as shielding gas. The selected input variables for TIG welding are welding current and inert gas flow rate. Parametric Optimization of TIG Welding on 316L Austenitic Present study focused on welding of austenitic stainless steel sheets using GTAW process with 316L material. The output variables are determined according to gas flow rate, travel speed and current. Grey relational analysis is applied to optimize the input parameters simultaneously considering the multiple output variables. Predicting the Weld Bead Geometry of GTA Welding on TIG welding is a highly non-linear, strongly coupled, multivariable process. The weld pool geometry and, hence, the quality of TIG welded joints are greatly dependent on the selection of input control variables such as welding speed (V), welding current (I), shielding gas flow rate (F) and gap distance (G).
