ED231012 - ArcWeld 528Mr E7018-1 Low Hydrogen Stick Electrode 2.5mm

Premium Low-Hydrogen Welding Electrodes for Industrial Applications

The ArcWeld 7018-1 528Mr Stick Electrode (2.5mm) is a high-performance consumable designed for the most demanding industrial welding environments. Engineered to meet the rigorous AWS E7018-1 classification, this electrode provides superior mechanical properties, specifically offering enhanced impact toughness at low temperatures compared to standard 7018 electrodes. This makes it an ideal choice for structural steel fabrication, bridge construction, and offshore projects where material integrity in cold climates is essential.

One of the standout features of the 528Mr series is its Moisture Resistant (MR) coating. In industrial settings, moisture absorption by the electrode coating can lead to hydrogen-induced cracking, a critical failure mode in high-strength steels. The MR coating significantly slows the rate of moisture pickup, extending the allowable exposure time under atmospheric conditions and ensuring low diffusible hydrogen levels in the weld metal. This reliability is crucial for fabricators adhering to strict welding codes and quality assurance standards.

The 2.5mm diameter is particularly versatile, allowing for precise control in root passes and welding on thinner sections of plate or pipe. The electrode operates with a smooth, stable arc on both DC+ and AC polarities, providing flexibility for various power sources found in maintenance shops and field sites. The iron powder addition in the coating assists in deposition rates and produces a fluid puddle that wets out evenly at the toes of the weld, reducing the need for post-weld grinding.

Josef Gas supplies the ArcWeld 7018-1 528Mr to support professionals who require consistency and quality. Whether used for pressure vessel fabrication, heavy equipment repair, or general construction, this electrode delivers X-ray quality welds with excellent bead appearance. Its all-position capability ensures that operators can tackle complex joints in the field without changing consumables.
