255012908 - AtomArc 7028 5/32" High Deposition Low Hydrogen Electrode

High-Performance Iron Powder Electrode for Structural Steel

The ESAB AtomArc 7028 is a premium quality, low hydrogen, iron powder stick electrode designed to maximize productivity in heavy industrial fabrication. Classified as an AWS E7028, this electrode is engineered with a heavy coating containing approximately 50% iron powder by weight. This unique formulation translates directly into higher deposition rates and faster travel speeds compared to standard E7018 electrodes, making it an indispensable asset for projects where large volumes of weld metal must be deposited efficiently.

Specifically formulated for welding carbon and low alloy steels, the AtomArc 7028 delivers exceptional mechanical properties, boasting a minimum tensile strength of 70,000 psi. Its low hydrogen characteristic ensures resistance to under-bead cracking and porosity, critical for maintaining the integrity of structural components in bridge construction, shipbuilding, and heavy machinery manufacturing. The electrode operates smoothly on both AC and DCEP (Direct Current Electrode Positive) currents, providing versatility in power source selection.

It is important to note that the AtomArc 7028 is designed exclusively for use in the flat and horizontal fillet positions. The heavy, fluid weld pool created by the iron powder coating allows for excellent wash-in at the toes of the weld and produces a flat, smooth bead profile with fine ripples. Slag removal is typically self-peeling or requires minimal effort, reducing post-weld cleanup time. For industrial applications requiring high-speed fillet welding or filling deep grooves in heavy plate, the AtomArc 7028 4.0mm (5/32") electrode offers a superior balance of speed, quality, and mechanical reliability.
