Welding Electrode Rod E7018

The E7018 classification denotes a tensile strength of 70,000 psi, all-position welding capability, and compatibility with both AC and DC+ currents. It is primarily used for structural steel, pressure vessels, bridges, pipelines, machinery frames, and shipbuilding, where weld integrity and toughness are essential. Production of E7018 electrodes involves a low-carbon steel core wire alloyed with manganese, silicon, and iron powder, coated with a special low-hydrogen flux to reduce moisture absorption and prevent hydrogen cracking. Each electrode undergoes controlled baking and drying to ensure stable arc characteristics and high-quality weld deposits that meet international standards.
