OVERVIEW

Superior Performance with ESAB OK 55.00

Elevate your welding projects with the ESAB OK 55.00, a top-tier E7018-1 stick electrode designed for welders who demand the best in strength and playability. This 3.2mm (1/8") electrode is a favorite among professionals for its smooth arc and forgiving nature, allowing for high-quality welds even in challenging positions. Whether you are repairing heavy machinery, fabricating structural frames, or working on pipe, the OK 55.00 provides the confidence that your welds will hold up under pressure.

The "1" in the E7018-1 classification signifies improved impact toughness, and the OK 55.00 delivers on this promise. It offers excellent ductility and impact strength at temperatures as low as -40°C, ensuring that your welds remain tough and resistant to brittle fracture in freezing conditions. This makes it an excellent choice for outdoor construction and repair work in Canadian winters. The electrode features a basic covering with low moisture absorption, which significantly reduces the risk of hydrogen cracking—a common issue in welding high-tensile steels.

Weldability is a key advantage of this rod. It runs smoothly on both AC and DC+ currents, providing flexibility depending on your power source. The arc is soft yet penetrating, ensuring good fusion at the root and sidewalls. Welders appreciate the manageable weld pool and the slag that lifts easily, revealing a clean, shiny bead underneath. This reduces the time spent chipping and grinding, allowing you to move on to the next pass or finish the job faster.

The ESAB OK 55.00 is particularly noted for its suitability in welding high-strength ship steels and general structural steels. It is a robust all-rounder that doesn't compromise on quality. When your work requires X-ray quality welds and superior mechanical properties, reaching for a pack of OK 55.00 is the smart choice. Ensure you have the right consumables to match your skills; choose ESAB for consistent results every time you strike an arc.

FAQ

The ESAB OK 55.00 is classified as AWS A5.1 E7018-1 H4 R, indicating it is a low-hydrogen electrode with improved toughness.

For the 3.2mm (1/8") diameter, the recommended amperage range is typically between 110 and 150 Amps.

Yes, ESAB OK 55.00 is designed to operate on both AC (Alternating Current) and DC+ (Direct Current Electrode Positive).

It is suitable for welding high-strength steels, unalloyed and low-alloyed steels, and is specifically approved for ship steel grades A, D, and E.

As a low-hydrogen electrode, it is highly recommended to store opened packs in a rod oven to prevent moisture pickup and ensure hydrogen control, especially for critical code work.

The '-1' suffix indicates that the electrode has been tested for impact toughness at a lower temperature (-45°C or -50°F) compared to standard E7018, making it better for cold environments.

Yes, the OK 55.00 is an all-position electrode, meaning it can be used for flat, horizontal, vertical-up, and overhead welding.
