TAGUCHI METHOD APPLIED FOR THE INVESTIGATION OF CORROSION LEVEL ON METAL INERT GAS WELDING OF MILD STEEL

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