3776323500 - E7018-1 Low Hydrogen Stick Electrode 1/8" (3.2mm) - 4.8kg Tube

Premium E7018-1 Low Hydrogen Stick Electrodes

This 4.80kg tube of E7018-1 Stick Electrodes (3.2mm / 1/8") is designed for professional welders requiring superior weld quality and mechanical properties. The E7018-1 classification indicates a low-hydrogen, iron powder electrode that offers exceptional impact toughness, particularly at lower temperatures, surpassing standard E7018 rods. This makes it the consumable of choice for critical structural applications where resistance to cracking and ductility are paramount.

Engineered for versatility, these electrodes perform exceptionally well in all welding positions, including flat, horizontal, vertical, and overhead. The 3.2mm (1/8") diameter is a standard size for general fabrication, allowing for deep penetration and strong fusion on medium-to-heavy gauge steel plates. The iron powder coating facilitates a smooth, stable arc with minimal spatter, resulting in a clean weld bead that requires less post-weld cleanup. Slag removal is typically easy, often self-releasing, which improves efficiency during multi-pass welding operations.

Critical Application Performance

The "-1" suffix in the AWS classification denotes that these electrodes have been tested to provide high impact values (Charpy V-Notch) at temperatures as low as -45°C (-50°F). This specific property makes them indispensable for industries such as:

• Structural Steel Construction: Bridges, buildings, and stadiums where code compliance is strict.


• Pressure Vessel Fabrication: Boilers and tanks requiring X-ray quality welds.


• Offshore and Marine: Rigs and ship hulls exposed to harsh, cold environments.


• Heavy Equipment Repair: Earthmoving machinery and cranes subject to high dynamic loads.

Packaged in a convenient 4.80kg tube, these electrodes are protected from moisture pickup, which is critical for maintaining their low-hydrogen status. For best results, it is recommended to store opened containers in a rod oven to prevent porosity and hydrogen-induced cracking.
