OVERVIEW

Heavy-Duty Welding with ESAB OK 55.00 6.0mm Rods

When your project demands maximum strength and reliability, the ESAB OK 55.00 E7018-1 stick electrode is the professional's choice. This 6.0mm diameter rod is built for heavy fabrication jobs where high deposition rates and deep penetration are required. Known in the industry for its robust performance, the OK 55.00 is a reliable, all-position low-hydrogen electrode that excels in environments where the weld metal must withstand significant stress and low temperatures. It is widely used in the welding of high-tensile steels, making it a staple for welders working on bridges, ships, and heavy industrial machinery.

The "-1" in the E7018-1 classification indicates that this electrode has been tested to provide superior impact toughness at temperatures as low as -45°C. This makes it far superior to standard 7018 rods for outdoor applications in cold climates or for structures subject to dynamic loading. The OK 55.00 is formulated to resist hot cracking, a common issue when welding thick sections of steel. Its advanced coating technology ensures a smooth, stable arc with minimal spatter, allowing for a comfortable welding experience even during long shifts. The slag system is designed for easy removal, reducing post-weld cleanup time and helping you get the job done faster.

Versatility is key in the welding shop, and the OK 55.00 delivers by running smoothly on both AC and DC+ currents. The 6.0mm size is a powerhouse for filling large bevels and multi-pass groove welds, significantly improving productivity compared to smaller diameter rods. It produces a bead with a fine ripple and excellent contour, ensuring that the finished weld not only holds strong but looks professional. This electrode is also highly capable when welding steels of unknown composition or steels with higher carbon content, acting as a safe buffer against cracking.

For welders who take pride in their work, the consistency of ESAB consumables is unmatched. The OK 55.00 provides excellent puddle control, allowing you to manipulate the weld pool effectively to tie into the sidewalls and prevent lack of fusion defects. Whether you are in the shipyard, on a pipeline spread, or in a heavy fabrication shop, stocking ESAB OK 55.00 6.0mm electrodes ensures you are ready to tackle the biggest and toughest welding challenges with confidence.

FAQ

The ESAB OK 55.00 is classified as an AWS A5.1 E7018-1 electrode, indicating it is a low-hydrogen rod with improved low-temperature impact toughness.

For the 6.0mm diameter OK 55.00, the recommended current range is typically between 220 and 360 Amps, depending on the position and base metal thickness.

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

The '-1' suffix indicates that the electrode has been tested for impact toughness at lower temperatures (typically -45°C) compared to standard E7018 electrodes, making it better for critical applications.

Yes, as low-hydrogen electrodes, they should be stored in a holding oven or re-dried according to the manufacturer's specifications if they have been exposed to moisture to prevent hydrogen cracking.

Absolutely. The OK 55.00 is specifically noted for its suitability in welding high-strength ships steel, including grades A, D, and E.

The 6.0mm diameter allows for higher deposition rates, making it ideal for filling large joints and welding thick sections of steel more efficiently.

Yes, the OK 55.00 is formulated to have high resistance to hot cracking and produces weld metal with very low hydrogen content to prevent cold cracking.
