Hobart 7018 XLM: Premium Low Hydrogen Stick Electrode

The Hobart 7018 XLM (Extra Low Moisture) is a high-performance carbon steel electrode designed for critical structural applications where weld integrity and hydrogen control are paramount. Conforming to AWS A5.1: E7018-1 H4R specifications, this electrode features a specialized coating that resists moisture pick-up, ensuring a diffusible hydrogen content of less than 4ml per 100g of weld metal. This H4R designation makes it an exceptional choice for welding high-strength, low-alloy steels susceptible to hydrogen-induced cracking, particularly in environments with high humidity or demanding code requirements.

Engineered with a substantial iron powder addition in the coating, the 7018 XLM delivers a high deposition rate, improving welding efficiency and travel speeds. The 5/32-inch (4.0 mm) diameter is optimized for heavy plate fabrication, offering deep penetration and robust fusion. It operates effectively on both Direct Current Electrode Positive (DCEP) and Alternating Current (AC), providing versatility across different power sources. The mechanical properties of the weld deposit meet the rigorous E7018-1 standards, offering superior impact toughness at low temperatures (typically -45°C), which is essential for industries like offshore construction, shipbuilding, and petrochemical infrastructure.

This product is supplied in a 50 lb (22.7 kg) hermetically sealed can. This premium packaging solution protects the electrodes from atmospheric moisture during storage and transport, ensuring they arrive in factory-fresh condition. For shops and field sites adhering to strict quality assurance protocols, the hermetic seal often reduces the immediate necessity for holding ovens upon initial opening, streamlining the workflow for critical path projects.

The Hobart 7018 XLM is suitable for single and multiple pass applications in all welding positions. Its formulation supports the welding of mild steel and low alloy structural steels found in bridges, power plants, and heavy equipment. By combining high metallurgical quality with practical usability, Hobart provides a consumable that meets the technical demands of welding engineers and quality control inspectors alike.
