In the present study, the PC-GTAW orbital welding parameters of AISI 304L stainless steel pipe have been optimized by using ANOVA and Taguchi method. The welding method uses Pulsatile Current-GTAW without added material (autogenous). Peak currents were varied in this study and had the same average current of 100 ± 0.5 amperes. The Taguchi method was applied to search for OBW, DoP and UTS that are optimal and L16 Taguchi's orthogonal array with two factors, four levels and two replications. S/N ratio with a quality character of larger is better (LB) was used to find the maximum value. The results show that raising the peak current would widen the OBW and deepen the DoP but reduce UTS. The 35-C parameter was the optimal parameter to produce OBW and DoP while the 100-C parameter was the optimal parameter to produce maximum UTS.
