ESAB OK 55.00 VP Mild Steel Electrode

The ESAB OK 55.00 VP is a versatile, high-quality LMA (Low Moisture Absorbing) electrode designed for welding high-strength low-alloy steels. It delivers exceptional performance, especially in applications requiring superior impact resistance and low-temperature toughness. The OK 55.00 VP offers excellent resistance to hot cracking, making it suitable for welding high-strength ship steels (Grades A, D, and E) and various structural applications. Tested to NACE TM0177 and TM0284 standards, this electrode provides reliable welds even in the most demanding environments.

With a diffusible hydrogen content below 3 ml/100g, the OK 55.00 VP minimizes the risk of hydrogen-induced cracking, making it highly effective in critical welding applications. Its compatibility with both AC and DC+ current adds flexibility, while the basic coating ensures smooth arc characteristics and easy handling for high-quality welds.

Key Features of ESAB OK 55.00 VP

  • High Impact Strength: Excellent low-temperature impact values, tested at -45°C (105 J) and -50°C (100 J).
  • VacPac™ Packaging: Moisture-free packaging prevents the need for re-baking, ensuring optimum weld quality.
  • Crack Resistance: High resistance to hot cracking, ensuring weld integrity in demanding applications.
  • Low Diffusible Hydrogen: Less than 3 ml/100g of diffusible hydrogen, reducing the risk of hydrogen-induced cracking.
  • Versatile Welding Current: Suitable for both AC and DC+ currents, providing flexibility in welding operations.
  • Reliable for High-Strength Steels: Ideal for welding high-strength ship steels (Grades A, D, and E) and similar applications.
  • LMA Technology: The Low Moisture Absorbing coating offers superior resistance to moisture, improving weld quality and durability.

Key Industry Applications

  • Shipbuilding: Essential for welding high-strength ship steels used in offshore vessels, cargo ships, and oil tankers. The electrode’s excellent resistance to seawater corrosion and dynamic stress makes it ideal for these harsh marine environments.
  • Structural Steel Fabrication: Perfect for fabricating bridges, high-rise buildings, and industrial plants. These projects demand superior impact resistance to withstand extreme weather conditions and heavy loads.
  • Offshore Platforms: Provides exceptional weld integrity in offshore oil rigs, wind farms, and floating production units. Especially when these structures are exposed to saltwater, high winds, and fluctuating temperatures, making crack-resistant welds crucial.
  • Pressure Vessels: Ideal for welding pressure vessels that contain gases and liquids under pressure, requiring high-strength, crack-resistant joints to ensure safety in industries like chemical processing.
  • Pipeline Welding: Suitable for pipelines in oil, gas, and water transmission, where welds must handle high pressures to prevent failure, in addition to handling corrosive materials and varying temperatures.
