ED038116 - Lincoln Easyarc 7018-1 5.0mm Low Hydrogen Stick Electrode

Industrial Grade E7018-1 Electrodes for Critical Applications

The Lincoln Electric Easyarc 7018-1 is a premium quality, low hydrogen stick electrode designed for heavy-duty industrial fabrication. Engineered to meet the rigorous AWS E7018-1 specifications, this electrode provides exceptional mechanical properties, specifically high impact toughness at temperatures as low as -45°C. This makes it the ideal choice for structural steel projects, bridges, offshore platforms, and pressure vessels where weld integrity cannot be compromised. The 5.0mm diameter is specifically suited for filling large joints and heavy plate welding, offering higher deposition rates compared to smaller diameter rods.

One of the standout features of the Easyarc 7018-1 is its Moisture Resistant (MR) coating. In industrial environments, moisture absorption by the electrode coating is a primary cause of hydrogen-induced cracking and porosity. The MR coating significantly slows the rate of moisture pickup, ensuring that the low hydrogen status of the consumable is maintained for longer periods after opening. This reliability is crucial for MRO operations and large-scale construction sites where storage conditions may vary. The iron powder addition in the coating further enhances the deposition efficiency, allowing for faster travel speeds and improved productivity on long weld runs.

Operators will appreciate the versatility of this electrode, which performs exceptionally well on DC+ polarity. It produces a flat to slightly convex bead profile with distinct ripple patterns and excellent tie-in at the toes of the weld. The slag system is designed to be self-releasing in many joint configurations, reducing the labor hours required for chipping and grinding between passes. For procurement managers and welding engineers, the Lincoln Easyarc 7018-1 represents a reliable, code-compliant solution that balances cost-effectiveness with superior metallurgical performance.
