OVERVIEW

Premium Grade Bohler E7018-1 Stick Electrodes for Critical Applications

The Bohler E7018-1 2.5mm Stick Electrode is a high-performance, basic-coated consumable designed for Shielded Metal Arc Welding (SMAW) of carbon and low-alloy steels. Engineered by Bohler Welding, a global leader in joining technology, this electrode is formulated to meet the rigorous demands of heavy industrial fabrication. The E7018-1 classification denotes a low-hydrogen iron powder electrode that offers exceptional impact toughness, specifically tested at temperatures as low as -45°C. This makes it the preferred choice for industries requiring high structural integrity, such as offshore construction, shipbuilding, pressure vessel fabrication, and heavy infrastructure projects.

One of the defining characteristics of this Bohler electrode is its metallurgical purity. The low hydrogen content (typically under 4ml/100g) significantly reduces the risk of cold cracking (hydrogen-induced cracking) in the heat-affected zone, a critical factor when welding thick sections or restrained joints. The 2.5mm diameter is versatile, allowing for precise root passes in pipe welding or detailed work on thinner gauge structural components where heat input control is paramount. The addition of iron powder to the coating improves deposition rates compared to standard E7018 electrodes, enhancing productivity without compromising the mechanical properties of the weld metal.

Supply chain managers and procurement specialists will appreciate the consistency and reliability associated with the Bohler brand. These electrodes are manufactured under strict quality control standards to ensure uniform coating concentricity and moisture resistance. Proper storage and handling are simplified due to the robust coating formulation, although standard re-baking procedures should be followed for code-quality work if the package is left open. Whether for on-site maintenance and repair operations (MRO) or large-scale fabrication shops, the Bohler E7018-1 provides a dependable solution that meets international welding codes and standards.

FAQ

The '-1' suffix indicates that the electrode has been tested for impact toughness at a lower temperature. Standard E7018 is tested at -29°C (-20°F), while E7018-1 is tested at -45°C (-50°F) to ensure ductility in colder environments.

For a 2.5mm (3/32 inch) E7018 electrode, the recommended amperage range is typically between 75 and 110 Amps. Start around 90A and adjust based on your travel speed and material thickness.

Yes, E7018-1 are low-hydrogen electrodes. Once the hermetically sealed package is opened, they should be stored in a holding oven at 120°C-150°C to prevent moisture pickup. If exposed to air for too long, they must be re-baked.

Yes, Bohler E7018-1 electrodes are designed to operate on both Direct Current Electrode Positive (DCEP) and Alternating Current (AC), providing flexibility for different power sources.

No, E7018 electrodes are designed for vertical-up welding. Vertical-down welding with basic coated rods can lead to slag entrapment and lack of fusion.

This electrode is suitable for welding carbon steels, high-strength low-alloy (HSLA) steels, and cast steels commonly used in construction and shipbuilding.

Ensure the base metal is clean and free of oil, grease, rust, and paint. Although 7018 can handle some contaminants, clean metal ensures X-ray quality results and prevents hydrogen cracking.
