61902400 - Bonarc E7024 High Deposition Stick Electrode 2.5mm (18kg Box)

High-Efficiency E7024 Carbon Steel Electrode

The Bonarc E7024 is a high-performance carbon steel stick electrode designed for applications requiring high deposition rates and superior weld bead aesthetics. Classified as an E7024 under AWS standards, this electrode features a heavy coating containing approximately 50% iron powder. This composition allows the electrode to carry higher currents than standard rods of the same diameter, resulting in a deposition rate that can be up to 50% faster than E6012 or E6013 electrodes. It is specifically engineered for flat and horizontal fillet welds, making it an excellent choice for heavy fabrication environments where production speed is critical.

This 2.5mm diameter electrode provides a smooth, stable arc with very low spatter levels. The heavy slag coverage protects the weld pool effectively and is often self-releasing upon cooling, minimizing post-weld cleanup time. The Bonarc E7024 operates effectively on AC, DCEN (Straight Polarity), and DCEP (Reverse Polarity), offering flexibility across different power sources. It produces welds with a slightly convex profile and fine ripples, suitable for structural steelwork, earthmoving equipment, and general heavy machinery fabrication.

Technical Specifications

The electrode delivers sound X-ray quality welds with excellent mechanical properties. It is best utilized in the flat position or for horizontal fillets where gravity assists in maintaining the large molten pool characteristic of high-deposition electrodes. Storage in a dry environment is recommended to maintain coating integrity, although it is not as moisture-sensitive as low-hydrogen alternatives.
