| Abstract Scope |
In this study, three commercial brands of E7018 electrodes were applied to evaluate their mechanical and microstructural properties, with one of them chosen as an AWS-approved reference. A-36 commercial steel with a thickness of 0.5 inches was used, employing a V-groove joint welded using the SMAW process in the 1G position. During welding, process variables such as travel speed, amperage, and arc length were kept constant. Tensile, hardness, and toughness tests were conducted using an INSTRON universal testing machine, a Buehler microhardness tester, and a Charpy impact testing machine (FIE, IT30), respectively. Additionally, a Keyence VHX-7000 digital microscope and a Jeol JSM-IT300 scanning electron microscope were used to observe existing phases and chemical composition. Mechanical properties were similar across all samples; however, different microstructures were observed. |
