S422032-033 - Hobart 7018 XLM 3/32" Low Hydrogen Stick Electrode (10lb Can)

Hobart 7018 XLM: Premium Low-Hydrogen Welding Electrodes

The Hobart 7018 XLM (Extra Low Moisture) is a high-performance carbon steel electrode designed for critical welding applications where hydrogen cracking is a primary concern. Engineered with a specialized iron powder coating, this electrode delivers high deposition rates and exceptional mechanical properties. The "XLM" designation signifies its superior resistance to moisture absorption, ensuring that the electrode maintains its low-hydrogen status for longer periods under varying atmospheric conditions. This makes it an ideal choice for industries requiring stringent adherence to welding codes, such as shipbuilding, offshore fabrication, and heavy structural steel erection.

Technically, the Hobart 7018 XLM is formulated to operate on both DC Electrode Positive (DCEP) and AC currents, providing versatility across different power sources. The 3/32" diameter is particularly effective for thinner gauge materials or for root passes in heavy plate welding where control and penetration are paramount. The electrode produces X-ray quality welds with excellent Charpy V-Notch impact toughness, making it suitable for low-alloy structural steels and field erections where dynamic loading may occur. The hermetically sealed 10lb can ensures that the electrodes are factory-fresh upon opening, minimizing the immediate need for reconditioning in a rod oven if used within the exposure time limits.

In industrial MRO environments, the reliability of the consumable is critical. The Hobart 7018 XLM reduces the probability of weld defects such as porosity and cracking, thereby lowering rework costs and downtime. Its ability to weld in all positions—flat, horizontal, vertical, and overhead—allows maintenance teams to perform complex repairs on-site without changing consumables. Whether used for tacking or full-penetration welds, this electrode provides the consistency required for high-stakes industrial maintenance and fabrication projects.
