Abstract

In this paper, the combination of shielded metal arc welding (SMAW) and gas tungsten arc welding (GTAW) welding methods are used in a double V groove SS304 10 mm thick plate. Welding current variation of 110A SMAW/120A GTAW, 100A SMAW/130A GTAW, and 90A SMAW/140A GTAW was used to observe the effect of the welding current variation on the tensile strength and microstructure. Tensile test and metallography test were performed to observe the phenomenon. ImageJ software was used for microstructure analysis. The welding current variation resulted in higher tensile strength with the highest current on GTAW method, while a more dispersed and lathy ferrite structure was observed on the microstructure.
