In metal manufacturing, welding and casting became an important focus in its development. Going to industrial era 5.0, efficiency in welding and casting is very important. Welding is one of the simplest methods of joining metals to form the desired machining structure. Shielded Metal Arc Welding has several variables that can affect the welding results. Current strength has an important influence on the quality of the weld. So research on the effect of current strength on the results of welded joints on its mechanical strength is needed. In this study, the mechanical strength tested is the tensile strength and the current susceptibility used is the commonly used 80 to 140 Ampere using ST-37 Steel. The highest maximum loading value occurs in the sample with a current of 80A. However, the highest fracture and yield loads occurred in the sample with a current of 140A. All types of the highest tension occur in the sample with a current using a current of 140A which has the potential to be able to withstand high tensile strength.
