Hobart 7018 XLM: Premium Low Hydrogen Electrode

The Hobart 7018 XLM (Extra Low Moisture) is a high-performance carbon steel electrode designed for critical welding applications requiring superior mechanical properties and hydrogen control. Classified as AWS E7018-1 H4R, this electrode features a specially formulated coating that resists moisture absorption, significantly reducing the risk of hydrogen-induced cracking in the weld zone. This makes it an ideal choice for welding low-alloy structural steels, offshore rigs, and high-stress fabrications where weld integrity is paramount.

Engineered for versatility, the 7018 XLM operates effectively on both DC Reverse Polarity (DCEP) and AC current. The 1/8-inch diameter is optimized for an amperage range of 100 to 160 amps, providing a stable, quiet arc with minimal spatter. The iron powder addition in the coating enhances deposition rates, allowing for faster travel speeds and increased productivity without compromising penetration or bead profile. Its all-position capability ensures consistent performance whether welding flat, horizontal, vertical, or overhead.

In addition to its welding characteristics, the Hobart 7018 XLM offers excellent Charpy V-Notch impact toughness at low temperatures, meeting the rigorous demands of industries such as shipbuilding, petrochemical, and heavy equipment manufacturing. The electrode produces a distinct, easily controllable weld puddle and slag that detaches easily, reducing post-weld cleanup time. Packaged in a 50lb hermetically sealed can, these electrodes are protected from environmental moisture until opened, ensuring factory-fresh performance.
