S422051-031 - Hobart 7018 XLM 5/32" Low Hydrogen Stick Electrodes (50lb Can)

Hobart 7018 XLM: Premium Low Hydrogen Electrodes for Critical Applications

The Hobart 7018 XLM (Extra Low Moisture) is a high-performance carbon steel electrode designed to meet the rigorous demands of critical structural fabrication. Engineered with a specialized coating that resists moisture absorption, this electrode maintains diffusible hydrogen levels below 4.0 ml/100g (H4R designation), significantly reducing the risk of hydrogen-induced cracking (cold cracking) in the heat-affected zone. This makes it an ideal choice for welding high-strength low-alloy steels where metallurgical integrity is paramount.

This 5/32-inch diameter electrode is formulated with a high percentage of iron powder in the coating, which enhances deposition rates and improves welding efficiency compared to standard non-iron-powder electrodes. The XLM formula ensures consistent X-ray quality welds, making it suitable for code-work in industries such as shipbuilding, offshore construction, and pressure vessel fabrication. It meets AWS A5.1 E7018-1 requirements, guaranteeing excellent impact toughness at temperatures as low as -50°F (-45°C).

Operable on both DC+ (Reverse Polarity) and AC current, the Hobart 7018 XLM offers versatility across various power sources. Its all-position capability allows for effective welding in flat, horizontal, vertical, and overhead positions, providing flexibility for complex field erections and maintenance operations. The 50lb hermetically sealed can ensures the electrodes reach the job site in factory-fresh condition, ready for immediate use in critical applications.
