5500604V0 - Esab OK 55.00 6.0mm E7018-1 Low Hydrogen Stick Electrodes VacPac

Premium Reliability for Heavy Fabrication

The Esab OK 55.00 is a legendary stick electrode in the world of industrial welding, renowned for its exceptional mechanical properties and reliability. This specific variant features a substantial 6.0mm diameter, making it a powerhouse for heavy fabrication tasks where high deposition rates are required. Classified as an E7018-1 H4 R, the OK 55.00 is engineered to weld high-strength low-alloy (HSLA) steels with confidence, delivering welds that stand up to rigorous testing and harsh environments.

One of the standout features of this product is its packaging. Supplied in Esab's innovative VacPac, these electrodes are vacuum-sealed to preserve their low-hydrogen characteristics indefinitely, provided the seal remains intact. For industrial facilities and field operations, this eliminates the costly and time-consuming requirement of rebaking rods or storing them in heated holding ovens before use. You can simply open the pack and weld with the assurance that the hydrogen content is kept to a minimum, significantly reducing the risk of cold cracking.

The 6.0mm diameter is specifically suited for the flat and horizontal positions, allowing welders to lay down significant amounts of metal in fill and cap passes on thick plate sections. It is widely used in critical industries such as power generation, shipbuilding, and offshore construction. The electrode provides a stable, smooth arc on both AC and DC+ currents, ensuring consistent penetration and excellent bead aesthetics. With impact toughness tested down to -45°C, the OK 55.00 is the electrode of choice for projects demanding superior ductility and structural integrity.

Key Industrial Benefits:

• No Ovens Required: VacPac technology saves energy and logistics costs.
• High Deposition: 6.0mm size speeds up welding on heavy sections.
• Certified Quality: Meets rigorous AWS and CSA standards for critical work.
