ANALYSIS OF THE EFFECT OF ELECTRODE VARIATION ON THE STRENGTH OF SMAW WELDING CARBON STEEL

Abstract

Indonesia has significant potential for resource development in the construction and manufacturing sectors. These sectors play a crucial role in the nation's economy, contributing substantially to national development. Therefore, the demand for metal and steel materials represents a business opportunity that can drive national economic growth.

This research aims to analyze the effect of electrode variation on the strength of SMAW welding on carbon steel using experimental methods. The study utilizes two types of electrodes, E6013 and E7016. The specimen for the impact test has dimensions of 4 mm thickness, 10 mm width, and 55 mm length, while the specimen for the tensile test has dimensions of 4 mm thickness, 40 mm width, and 160 mm length.

The results indicate that electrode variation affects the tensile strength of SMAW welding on carbon steel, with a value of 466.075 MPa for the E7016 electrode and 388.7 MPa for the E6013 electrode. Additionally, for the impact strength test, electrode variation also influences the welding results, with a value of 99.8° for the E7016 electrode and 97.2° for the E6013 electrode.
