Hyundai Electrode 7018 4.0mm – Low Hydrogen Welding Electrode
Product Overview
The Hyundai 7018 4.0mm Welding Electrode is a premium low-hydrogen, iron-powder coated electrode engineered for high-strength, crack-resistant welds on carbon and low-alloy steels. Widely trusted by professional welders, fabricators, and construction contractors, this AWS E7018 classification electrode delivers smooth arc characteristics, minimal spatter, and excellent mechanical properties — making it a top choice for structural steel welding, pipeline work, shipbuilding, and heavy fabrication projects.
Key Features
- Diameter: 4.0mm (5/32") — ideal for medium to heavy-duty welding applications
- Classification: AWS A5.1 E7018 / low-hydrogen potassium type coating
- Tensile Strength: Approximately 70,000 PSI (490 MPa) minimum yield strength
- Coating Type: Low hydrogen, iron powder coating for higher deposition efficiency
- Current Type: AC/DC+ (DCEP) compatible
- Arc Characteristics: Smooth, stable arc with easy slag removal
- Weld Quality: X-ray quality welds with excellent ductility and impact toughness, even at low temperatures
Benefits of Hyundai 7018 Electrodes
- Superior Weld Strength – Produces high-tensile, crack-resistant welds suitable for critical structural applications.
- Low Hydrogen Formulation – Significantly reduces the risk of hydrogen-induced cracking, especially important for thick sections and high-carbon steels.
- Excellent Bead Appearance – Delivers a smooth, uniform bead with minimal spatter, reducing post-weld cleanup time.
- Easy Slag Removal – Self-releasing slag speeds up multi-pass welding operations.
- Versatile Positional Welding – Suitable for flat, horizontal, vertical, and overhead welding positions (depending on specific product variant).
- High Deposition Rate – Iron powder coating boosts productivity without compromising weld integrity.
Recommended Applications
- Structural steel fabrication and construction
- Pressure vessel and boiler manufacturing
- Pipeline and pipe welding
- Shipbuilding and heavy equipment repair
