61884000 - Bonarc 7018 Low Hydrogen Stick Electrode 4.0mm

Premium Quality Bonarc 7018 Electrodes for Structural Integrity

The Bonarc 7018 4.0mm Steel Stick Electrode is a high-performance consumable designed for demanding industrial applications where weld integrity is paramount. As a low-hydrogen, iron-powder electrode, it is engineered to produce high-quality welds with excellent mechanical properties, specifically high tensile strength and ductility. This electrode meets AWS E7018 classifications, making it a standard choice for code work in construction, shipbuilding, and heavy equipment manufacturing.

One of the defining characteristics of this Bonarc electrode is its radiographic soundness. It is formulated to deposit weld metal that is free of porosity and defects, ensuring it passes X-ray inspections required for critical infrastructure such as pressure vessels and structural steel frameworks. The 4.0mm diameter is particularly suited for welding thicker plates and heavy-wall pipes, providing the necessary heat input and filler metal volume for efficient multi-pass welding.

Operational efficiency is enhanced through the electrode's superior arc characteristics. It offers stable arc performance on both Direct Current Electrode Positive (DCEP) and Alternating Current (AC), providing flexibility depending on the power source available. The iron powder addition in the coating assists in higher deposition rates, allowing for faster travel speeds and increased productivity in fabrication environments. Furthermore, the electrode is designed to minimize moisture pickup, although standard storage in rod ovens is recommended to maintain its low-hydrogen status.

For procurement managers and facility operators, the Bonarc 7018 represents a reliable solution that balances cost-effectiveness with premium performance. Its consistent burn-off rate and reduced spatter levels contribute to lower post-weld cleanup costs and higher throughput in production schedules.
