Abstract

Welding is a process of connecting between two or more metal parts using a thermal energy, heat energy in the welding process triggers corrosion of the metal. This study aims to determine the effect of strong variations in current and electrodes on the corrosion rate on SS 400 elbow plates. In this study, elbow-shaped plates were welded using SMAW welding with strong currents of 60 A and 70 A, electrodes E6013 and E7016. SS 400 elbow plates are welded and then subjected to preliminary weighing and visual observation of the HAZ portion of each specimen, before being immersed for seven days in nitric acid (HNO3). Nitric acid in this study serves as a corrosive solution. After seven days of reweighing and visual observation, to determine the weight and changes in the HAZ area after the soaking process. The largest corrosion rate occurs at a current of 70 A with Electrode E6013 of 0.0689 mpy, and the smallest at a current of 60 A with Electrode E7016 of 0.0136 mpy. From this study, the strong current and electrodes affect the corrosion rate of SMAW welding results, the higher the welding current, the higher the corrosion rate produced.
