Hobart 418 E7018-1 Low Hydrogen Electrode

The Hobart 418 is a premium quality, low hydrogen carbon steel electrode designed for demanding industrial applications. Classified as AWS E7018 H4R and E7018-1 H4R, this 3/32-inch stick electrode delivers exceptional performance in all welding positions. It is engineered to produce X-ray quality welds with high impact toughness, making it a preferred choice for critical structural work where weld integrity is paramount. The electrode features a moisture-resistant coating that helps prevent hydrogen-induced cracking, a crucial factor in heavy fabrication and infrastructure repair. The H4R designation specifically indicates that the electrode meets stringent diffusible hydrogen limits and maintains its low-hydrogen properties even after exposure to high humidity environments for extended periods.

Packaged in a 50 lb hermetically sealed can, the Hobart 418 ensures freshness and immediate usability upon opening, eliminating the need for initial rebaking if the seal is intact. It operates effectively on both DCEP and AC polarities, providing versatility for various power sources found in industrial settings. The arc characteristics are smooth and stable, resulting in minimal spatter and a flat bead contour. Slag removal is notably easy, reducing post-weld cleanup time and improving overall productivity. This electrode is particularly well-suited for welding low alloy structural steels, high carbon castings, and pressure vessels found in power and petrochemical plants.

With a tensile strength of approximately 78,500 psi and a yield strength of 65,500 psi, the Hobart 418 meets the rigorous mechanical requirements of the E7018-1 designation. It offers excellent wetting action and start/restart capabilities, even on challenging joints or slightly contaminated surfaces. Whether used for single or multiple pass applications, this electrode provides consistent, reliable results for maintenance, repair, and new construction projects across the mining, rail, and shipbuilding industries. Its ability to maintain mechanical properties at lower temperatures makes it an essential consumable for projects requiring high impact resistance.
