N2 - In this study, the effect of welding current and welding speed on the weld geometry and distortion in TIG welding process was investigated. The material used in this experiment is A36 mild steel pipe. The dimensions of specimen were 114.3 mm of outer diameter and 6 mm of thickness. The wire feeder used was ER70-S 6 with a V-groove joint as a type welding joint. The welding parameters varied were the welding current and welding speed. Welding results will be tested for weld geometry (outer bead width) and distortion after the welding process. The weld geometry was measured using Digital Microscope and the distortion was measured using outside micrometers before and after the welding process. The results show that increasing the welding current can widen the weld bead and increase distortion. While increasing the speed has little effect on the weld bead and distortion. Welding parameters with a welding current of 170 A and a welding speed of 0.9 mm/s produces the widest outer bead and the biggest tapers and distortion. In addition, the results of tapers and distortion in the axial direction were greater than the transverse direction of the pipe.
