摘要：The effect of the welding process on porosity formation in SPCC carbon steel was studied by comparing MIG, MAG, and TIG welding processes. In this work, the main consideration relates to the welding processes, which are welding current, welding speed, and heat input were investigated. Industrial x-ray observation was performed to study the distribution of porosity within the weld bead. Analysis of bead geometry shows the deepest penetration in TIG welding. The most significant size of porosity was shown in MAG welding compared to MIG and TIG welding. The result indicates that an increase in heat input affects the size of porosity distribution and depth penetration of the weld bead.
