TOKO AWS A5.1 E7018 Welding Electrode
TOKO E7018, E7016 Low-Hydrogen, All-Position Welding Electrode for Critical Structural Welding | TOKO E7018 welding rods deliver consistently reliable welding performance, earning proven customer satisfaction across shipbuilding, structural fabrication, and heavy machinery applications.
Key Advantages
- AWS A5.1 Certified: Compliant with international standards for shielded metal arc welding (SMAW).
- Low-Hydrogen Formula: Minimizes hydrogen-induced cracking in high-strength applications.
- All-Position Welding: Exceptional performance in flat, horizontal, vertical-up, and overhead positions.
- High Tensile Strength: 70,000 psi (490 MPa) weld metal strength.
- Impact Toughness: Maintains ≥27J at -30°C for cold-weather resilience.
Performance Benefits
- Smooth Arc Stability: Reduced spatter and easy slag removal.
- Deep Penetration: Ideal for thick materials and root passes.
- Crack Resistance: Low hydrogen levels (<5ml/100g) prevent HIC.
- Versatile Compatibility: Works on carbon steel, high-strength steel, and some low-alloy steels.
Common Applications
- Structural steel fabrication (beams, columns, bridges)
- Pressure vessel and pipeline welding
- Heavy machinery repair and maintenance
- Shipbuilding and offshore platforms
- Critical joints requiring X-ray quality welds
