S115951-035 - Hobart 718 E7018-1 Stick Electrode 5/32 Inch 50lb Can

Technical Overview of Hobart 718 (E7018-1) Electrodes

The Hobart 718 is a premium low-hydrogen stick electrode designed to meet the rigorous demands of critical structural and industrial applications. Classified as AWS E7018-1 H4R, this electrode is engineered to provide superior mechanical properties, particularly in low-temperature environments where impact toughness is essential. The "-1" designation indicates that the weld metal meets specific Charpy V-Notch impact requirements at -45°C (-50°F), making it an excellent choice for industries such as shipbuilding, offshore drilling, and heavy equipment manufacturing operating in harsh climates.

One of the standout technical features of the Hobart 718 is its iron powder coating, which facilitates higher deposition rates compared to standard non-iron powder electrodes. This results in increased productivity and travel speeds without compromising weld quality. The electrode is formulated to offer exceptional moisture resistance (H4R), significantly reducing the risk of hydrogen-induced cracking—a critical factor when welding high-strength low-alloy steels or thick sections. It produces X-ray quality welds with excellent bead appearance and consistent penetration.

Operable on both Direct Current Electrode Positive (DCEP) and Alternating Current (AC), the Hobart 718 provides versatility for various power sources. Its arc characteristics are smooth and stable, ensuring ease of control even during out-of-position welding. The slag system is designed for easy removal, often self-peeling, which minimizes post-weld cleanup time and reduces the likelihood of slag inclusions in multi-pass welds. This 50lb can packaging ensures a substantial supply for large-scale fabrication projects while the hermetic seal protects the electrodes from atmospheric moisture prior to opening.

In summary, the Hobart 718 combines high operator appeal with robust metallurgical performance, making it a preferred consumable for code-quality work in the petrochemical, power generation, and construction sectors.
