Offshore Wind Power Welding Consumables

Offshore wind power structures operate in harsh marine environments, exposed to high salinity, humidity, tidal fluctuations, and strong wind loads. Key welded components such as tower sections, nacelle bases, foundations, and transition pieces require not only high strength but also excellent toughness and corrosion resistance to ensure a service life of over 20 years.

▎Performance Requirements

  • High Strength & Toughness
  • Weld metal yield strength ≥ 355 MPa or higher grade
  • Impact toughness requirements at -40°C or even -60°C to ensure safety in low-temperature conditions
  • Excellent Corrosion Resistance
  • Withstand seawater, salt spray, and splash zone corrosio
  •  Compatible with weathering steel and marine coating systems
  • Low Hydrogen & Crack Resistance
  • Minimized diffusible hydrogen to reduce cold cracking risk
  • Good resistance to lamellar tearing
  • High Welding Efficiency
  • Supports high-current, high-deposition automated welding processes (e.g., SAW, FCAW, GMAW)
  • Suitable for thick plate multi-pass welding
