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.

Advantages include high tensile and impact strength, low spatter, smooth bead finish, and resistance to cracking and porosity. E7018 electrodes produce welds of excellent ductility and X-ray quality suitable for critical applications. They are available in 2.5 mm, 3.2 mm, 4.0 mm, and 5.0 mm diameters, supplied in 5 kg and 20 kg hermetically sealed moisture-proof boxes, palletized for industrial and export use. E7018 remains the professional welder’s choice for dependable performance in demanding structural and high-pressure environments.
