Abstract

Welding is a metallurgical bond on metal alloy joints that is performed while the metal alloy is melted or liquid. The purpose of this research is to determine the effect of the electrode types E 6010 and E 7016 on the mechanical properties and microstructure of API 5L low carbon steel during SMAW welding. The welding electrodes are E 6010 and E7016, and the welding current is 110A. The welding seam used is a v-groove with a 60o angle. Welding samples were cut and machined into standard configurations for tensile strength, impact, and hardness tests, as well as SEM for microstructure analysis. The results show that the type of electrode has a significant effect on mechanical properties such as tensile strength, impact, and hardness of the welding metal. Welding electrodes of various types are used as the welding variable. The E 7016 electrode has the highest tensile strength with a tensile strength value of 617 MPa, while the E 6010 electrode has a tensile strength of 554 MPa, and the E 7016 electrode has the highest toughness with a toughness value of 1.856 Joules / mm2. The E 7016 weld metal area had the highest average hardness of186.9 VHN. SEM microstructure analysis reveals several phases, including Acicular Ferrite (AF), Grain Boundary Ferrite (GBF), and Bainite.
