ED029050 - Lincoln Excalibur 7018-1 MR 4.0mm Low Hydrogen Stick Electrodes

Premium Low-Hydrogen Electrodes for Critical Applications

The Lincoln Electric Excalibur 7018-1 MR is a top-tier mild steel stick electrode designed for fabrication environments where weld integrity and efficiency are paramount. Engineered with a specialized moisture-resistant (MR) coating, this electrode significantly reduces the absorption of atmospheric moisture, maintaining low diffusible hydrogen levels in the weld deposit. This feature is critical for preventing hydrogen-induced cracking (cold cracking) in high-strength steels and restrained joints, making it a preferred choice for code-quality work in construction, petrochemical, and power generation sectors.

With a diameter of 4.0mm, this electrode is optimized for filling joints in medium-to-heavy plate thicknesses. It meets AWS E7018-1 H4R requirements, offering improved impact toughness at lower temperatures compared to standard E7018 electrodes. This makes it suitable for projects requiring high ductility and resilience in harsh operating conditions. The manufacturing process ensures consistent core wire concentricity and coating thickness, resulting in a stable arc and uniform burn-off rate that professionals can rely on for X-ray quality welds.

Procurement managers and welding engineers choose the Excalibur series for its proven track record in reducing rework. The easy slag removal and minimal spatter generation translate to lower post-weld cleaning costs and faster turnaround times on the shop floor or job site. Whether used for structural steel erection or pressure vessel fabrication, the ED029050 delivers the mechanical properties and operational consistency required for high-stakes industrial projects.
