Key Features of E7018 Electrodes

1. Low-Hydrogen Properties

• Special flux coating reduces hydrogen diffusion into the weld metal, preventing hydrogen-induced cracking (cold cracking).
• Provides reliability in welding medium-carbon and low-alloy steels.

2. Excellent Mechanical Properties

• Minimum tensile strength: ≥ 70 ksi (490 MPa).
• Outstanding impact toughness, even at low temperatures.
• Delivers durable welds for critical load-bearing structures.

3. Superior Welding Performance

• Stable arc with smooth bead appearance.
• Low spatter and easy slag removal, improving efficiency on the job site.
• Suitable for all-position welding (flat, vertical, overhead, horizontal).

4. Versatile Power Compatibility

• Best results with DCEP (Direct Current Electrode Positive).
• Compatible with AC welding machines when needed.

Typical Applications

E7018 electrodes are widely applied in:

• Structural steel fabrication – bridges, high-rise buildings, offshore platforms.
• Shipbuilding and marine engineering – hulls, decks, and critical joints.
• Pressure vessels and boilers – requiring welds resistant to cracking.
• Pipelines and heavy machinery – where strength and reliability are crucial.

Handling & Storage Recommendations

To ensure optimal performance:

• Bake electrodes at 350–400℃ for 1–2 hours before use.
• Store in dry conditions to prevent moisture absorption.
• Use immediately after baking to maintain low-hydrogen properties.
