MATRIX 7018 Electrode

The MATRIX E7018 welding electrode is one of the most widely used and trusted low-hydrogen electrodes in the welding industry. Classified under the AWS A5.1 specification, this electrode is specifically designed to produce high-quality, high-strength welds in mild and low-alloy steels. With a tensile strength of 70,000 psi, E7018 electrodes are ideal for critical welding applications that demand structural integrity, crack resistance, and excellent mechanical properties.

Whether you’re welding bridges, buildings, pipelines, or pressure vessels, the E7018 Electrode delivers unmatched performance, reliability, and ease of use. It’s a go-to choice for both professional welders and industrial fabrication teams.

Key Features

  • Low Hydrogen Content: Minimizes the risk of hydrogen-induced cracking.
  • High Tensile Strength: 70,000 psi minimum tensile strength (hence the “70” in E7018).
  • Excellent Weld Bead Appearance: Produces clean, smooth, and X-ray quality welds.
  • All-Position Welding: Suitable for flat, horizontal, vertical, and overhead welding.
  • Iron Powder Coating: Enhances deposition rates and arc stability.
  • Easy Slag Removal: Reduces clean-up time for higher productivity.

Typical Applications

  • Heavy steel structures
  • Bridges and buildings
  • Ship construction
  • Pressure vessels
  • Pipe welding
  • Repair and maintenance work
