This paper represents a review on TIG welding and effect of various process parameters on TIG welding process. GTAW plays an important role in those industries where it is important to control the metallurgical properties and weld bead shape. TIG welding process compared to other arc welding process, low heat affected zone, no slag, in a single pass its productivity is relatively low and high heat concentration. Knowledge of process variables is important and necessary to produce weld of satisfactory quality. The parameters such as welding speed, current, voltage, gas flow rate etc. affects the weld strength in the form of weld bead geometry and mechanical strength. Various techniques are proposed in literature to achieve the better optimization of these parameters.
