61882400 - Bonarc E7018 Low Hydrogen Welding Rods 2.5mm

High-Performance Low Hydrogen Electrodes

The Bonarc 7018 2.5mm Steel Stick Electrode is a premium quality consumable designed for Shielded Metal Arc Welding (SMAW) of carbon and low-alloy steels. Engineered to meet AWS E7018 specifications, this electrode features a low hydrogen, iron powder coating that provides excellent deposition rates and superior mechanical properties. It is an ideal choice for industrial supply inventories catering to construction, fabrication, and maintenance sectors where weld integrity is paramount.

Operational Efficiency and Quality

One of the defining characteristics of the Bonarc 7018 is its user-friendly arc behavior. It offers very good striking and re-striking properties, which significantly reduces the frustration of rod sticking and start-up porosity. The electrode produces a smooth, stable arc with minimal spatter, resulting in a flat to slightly convex bead profile with fine ripples. The slag system is designed for easy detachment, often curling up on its own, which reduces post-weld cleaning time and labor costs.

Technical Specifications and Applications

This 2.5mm diameter electrode is versatile enough for all-position welding, making it suitable for complex joints in the field. It operates effectively on both AC and DC+ (Reverse Polarity) currents. The weld metal deposited exhibits high tensile strength (minimum 70,000 psi) and excellent impact toughness, ensuring radiographic soundness. It is extensively used in the fabrication of pressure vessels, heavy machinery, structural steel frameworks, and shipbuilding. Proper storage in a rod oven is recommended to maintain its low hydrogen status and prevent moisture pickup.

Reliability for Critical Welds

Bonarc has formulated this electrode to address the common challenges faced in heavy industrial welding. The inclusion of iron powder in the coating assists in higher current carrying capacity compared to standard electrodes, allowing for faster travel speeds without compromising fusion. Whether for code-quality work or general repair, the Bonarc 7018 delivers consistent, high-quality results that professionals trust.
