| Summary: | Mild steel has a wide range of uses, such as in the construction field, automotive field, machinery industry, cookware, and pipeline. Metal Inert Gas (MIG) welding acts as an assembly method for mild steel. Corrosion level is a common problem that occurs in MIG welding on mild steel. In this study, the suitable welding parameters such as voltage, number of passes, and method of welding were chosen in the experimental testing, and the experimental testing was planned by using the Design of Experiment (DoE) as part of the Taguchi method. The welded mild steel specimens were evaluated using a corrosion test. The data analysis was done by using the Taguchi method.For the parameter to be the optimum welding parameter, the corrosion level was as low as possible. In this case, the S/N ratio is smaller, and the best common interest is chosen. By using the Minitab 18 software, the S/N ratio was calculated. Hence, from the result, the optimum parameters are: 9V voltage, three passes, and the welding method was circle push.
