Product description

E7018 H4R Welding Rod- Technical Specifications

AWS Classification Manufactured in compliance with AWS A5.5 E7018 H4R standards, ensuring consistent chemistry, low hydrogen content, and reliable weld quality.
High Tensile Strength High Tensile Strength Delivers a minimum tensile strength of approximately 70,000 PSI, providing strong and durable welds suitable for structural steel, bridges, pipelines, and heavy fabrication.
Low Hydrogen Content Hydrogen content is controlled to ≤5 ml/100 g of deposited metal, reducing the risk of cracking in high-strength and low-temperature applications.
Stable Arc Performance Produces a smooth, stable arc with minimal spatter, improving bead appearance and reducing cleanup time.
All Position Welding Engineered for welding in flat, horizontal, vertical, and overhead positions for versatile application across different projects.
Welding Current Compatibility Compatible with AC and DC welding currents, allowing flexibility for various welding setups and equipment.
Easy Residue Removal Post weld residue peels off cleanly, leaving a smooth, defect-free weld surface.
Recommended Applications Ideal for structural steel, pressure vessels, pipelines, bridges, heavy machinery, and repair work requiring low hydrogen welding.
  • What welding machines can I use E7018 H4R rods with?

    These rods are compatible with AC and DC welding machines, including stick/arc welders used for structural steel, pipelines, heavy equipment, and industrial fabrication.

  • What metals can I weld with E7018 H4R?

    E6011 electrodes are designed for mild steel and low-carbon steel, especially when surfaces are rusty, painted, or difficult to clean.

  • How should I store leftover rods?

    Keep them in the plastic case for long-term storage. Avoid moisture and extreme temperature changes to maintain low-hydrogen integrity.

  • Why should I pick E7018 H4R over cheaper rods?

    These rods give strong, crack-free joints with minimal spatter and smooth post weld residue removal.

  • How do I insert the rod into the machine?

    Securely place the E7018 H4R rod in a standard electrode holder. Ensure free current flow for a stable arc and consistent weld quality.
