812000255 - ESAB Sureweld E7024-1 High Deposition Stick Electrode 4.0mm

Technical Overview of ESAB Sureweld 7024-1

The ESAB Sureweld 7024-1 is a high-efficiency, heavy-coated manual metal arc (MMA) welding electrode designed for industrial applications requiring rapid metal deposition. Classified under AWS A5.1 as E7024-1, this electrode features a coating rich in iron powder (approximately 50% of the coating weight), which significantly enhances the metal recovery rate. The 4.0mm diameter configuration is optimized for high-amperage operation, facilitating deep penetration and substantial weld build-up in a single pass. The "-1" suffix indicates that this specific formulation meets supplemental impact requirements, offering better toughness properties than standard E7024 electrodes.

Engineered primarily for flat and horizontal fillet welds, the Sureweld 7024-1 operates with a smooth, spray-type transfer that is characteristic of rutile-iron powder coatings. The heavy slag system is designed to support the molten pool at high travel speeds, ensuring a consistent bead profile. Upon cooling, the slag is self-releasing in most instances, minimizing post-weld cleaning time and labor costs. This electrode is compatible with both Alternating Current (AC) and Direct Current (DC), providing versatility across different power sources found in industrial environments.

From a metallurgical perspective, the deposited weld metal exhibits excellent mechanical properties, suitable for mild and low-alloy steels. The high deposition efficiency makes it a superior choice for filling large grooves or creating heavy fillets where productivity is a critical metric. It is widely utilized in the fabrication of earthmoving equipment, structural girders, railcars, and shipbuilding components where long, continuous welds are common. Proper storage in a dry environment is recommended to maintain the integrity of the hydroscopic coating.
