| 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.
