The Atlantic E7018 4.0mm (5/32") Mild Steel Electrode is a high-quality consumable designed for Shielded Metal Arc Welding (SMAW) of carbon and low-alloy steels. Engineered with a moisture-resistant, low-hydrogen potassium iron powder coating, this electrode is specifically formulated to produce welds with exceptional mechanical properties and resistance to cracking. It meets AWS A5.1 specifications, ensuring reliability in critical structural applications where weld integrity is paramount.
One of the defining characteristics of the Atlantic E7018 is its iron powder addition, which significantly enhances the deposition rate compared to standard non-iron powder electrodes. This feature allows for faster travel speeds and increased productivity in heavy fabrication environments. The electrode provides a smooth, stable arc that is easy to control, resulting in a flat to slightly convex bead profile with fine ripples. The slag system is designed for easy detachment, often curling up on its own as the weld cools, which reduces downtime associated with inter-pass cleaning.
These electrodes are capable of producing X-ray quality welds with excellent Charpy V-Notch impact toughness, making them suitable for use in dynamic loading conditions and low-temperature environments. They are compatible with both Direct Current Electrode Positive (DCEP) and Alternating Current (AC) power sources, offering flexibility depending on the available equipment. Proper storage and handling are essential; like all low-hydrogen consumables, these electrodes should be stored in a holding oven after opening to maintain their low moisture content and prevent hydrogen-induced cracking.
