3776253500 - E7018-1 Low Hydrogen Stick Electrode 3/32" (2.5mm) - 4.5kg Tube

High-Performance E7018-1 Low Hydrogen Electrodes

The Stick Electrode Weld 7018-1 2.5 mm (3/32") is a premium quality, low hydrogen, iron powder type electrode designed for shielded metal arc welding (SMAW) of carbon and low-alloy steels. Conforming to AWS A5.1 E7018-1 classification, this electrode is engineered to provide exceptional mechanical properties, specifically high impact toughness at low temperatures (typically down to -45°C). This makes it the preferred choice for critical structural applications where resistance to brittle fracture is paramount, such as in offshore structures, bridges, and heavy machinery operating in cold climates.

The 2.5mm (3/32") diameter is versatile, allowing for precise control in various welding positions, including flat, horizontal, vertical-up, and overhead. The iron powder addition in the coating improves the deposition rate and arc stability, resulting in a smooth, quiet arc with low spatter levels. Operators will appreciate the easy slag removal and excellent bead appearance, reducing post-weld cleaning time. The electrode produces X-ray quality welds, ensuring integrity in pressure vessels, piping, and boiler fabrication. The chemical composition is strictly controlled to ensure consistent performance and compliance with industry standards such as ASME SFA-5.1.

Packaged in a convenient 4.5 kg tube, these electrodes are protected from moisture pickup, which is critical for maintaining their low hydrogen status. Proper storage and handling (using rod ovens) are recommended to prevent hydrogen-induced cracking in the heat-affected zone of the base metal. The coating is designed to resist moisture absorption better than standard basic electrodes, but adherence to handling protocols ensures the highest quality results. Whether for maintenance, repair, or new fabrication, the E7018-1 offers the reliability and strength required for heavy-duty industrial projects.

This electrode is compatible with both AC and DC+ (Reverse Polarity) power sources, offering flexibility in shop and field environments. The arc initiation is reliable, and the restrike capability is optimized to minimize porosity at the start of the weld. For engineers and fabricators demanding superior toughness and ductility in their weld metal, the E7018-1 specification is the industry standard for excellence.
