S422051-033 - Hobart 7018 XLM 5/32" Stick Electrodes - 10lb Can

Premium Low-Hydrogen Structural Electrodes

The Hobart 7018 XLM 5/32" Stick Electrode is a high-performance filler metal designed for critical welding applications requiring superior mechanical properties and hydrogen control. As an AWS E7018-1 H4R classified electrode, the XLM (Extra Low Moisture) formulation is engineered to resist moisture pick-up in high-humidity environments, significantly reducing the risk of hydrogen-induced cracking in the heat-affected zone. This makes it an ideal choice for structural steel fabrication, offshore platform construction, and heavy industrial repairs where code compliance and weld integrity are paramount.

Packaged in a convenient 10 lb hermetically sealed can, these electrodes are protected from atmospheric moisture until the moment of use. The 5/32" diameter is well-suited for heavier plate welding, offering a high deposition rate due to its iron powder coating. The electrode operates smoothly on both DC+ (Reverse Polarity) and AC current, providing flexibility for various power sources found in field and shop environments. With a tensile strength exceeding 70,000 psi and excellent Charpy V-Notch impact toughness at low temperatures, the Hobart 7018 XLM meets the rigorous demands of the petrochemical, shipbuilding, and power generation industries.

Operational Efficiency and Quality

Industrial fabricators choose the Hobart 7018 XLM for its balance of metallurgical quality and operator appeal. The electrode produces a quiet, stable arc with minimal spatter, reducing post-weld cleanup time. Its slag system is designed for easy removal, often peeling away on its own, which is critical for multi-pass welding applications to prevent slag inclusions. Whether welding in the flat, horizontal, vertical, or overhead positions, the puddle remains easily controllable, allowing for high-quality bead profiles even in difficult out-of-position joints.

For MRO professionals and structural welders, the reliability of the Hobart 7018 XLM translates to fewer rework cycles and higher productivity. The "1" suffix in the E7018-1 classification indicates improved impact properties compared to standard 7018 rods, making this product suitable for low-temperature service applications. Trust Hobart's legacy of filler metal excellence for your most demanding projects.
