In carbon steel butt joint welding, uniform back bead formation and reduction of weld deformation are important. In most industrial sites, Ceramic backing is used for V-grooves for uniform back bead formation in FCAW and SAW. In this case, because the root pass has a large deposition area and a high heat input, a problem can occur where angular distortion occurs during cooling. In this study, to reduce weld deformation and form uniform back beads that angular distortion was measured using
