OVERVIEW

Industrial Grade E7018-1 Stick Electrode for Critical Structural Applications

The Stick Electrode Weld 7018-1 5.0 mm (3/16") is a premium quality, low hydrogen, iron powder electrode designed for heavy-duty shielded metal arc welding (SMAW). Engineered to meet the rigorous AWS A5.1 E7018-1 classification, this consumable offers exceptional mechanical properties, specifically high impact toughness at low temperatures (Charpy V-Notch properties at -45°C). This makes it the ideal choice for welding structural steels in bridges, offshore platforms, pressure vessels, and heavy machinery where resistance to brittle fracture is paramount.

The 5.0mm (3/16") diameter is optimized for filling large grooves and creating substantial fillet welds on thick plate sections. The inclusion of iron powder in the coating significantly increases the deposition rate, allowing for faster travel speeds and improved productivity compared to non-iron powder electrodes. Furthermore, the extended 18-inch length is a critical efficiency feature; it allows welders to lay down longer beads before needing to stop and replace the electrode, thereby reducing the number of starts and stops—common points for potential defects.

This electrode is formulated to produce X-ray quality welds with excellent ductility and crack resistance. It operates best on Direct Current Electrode Positive (DCEP), providing deep penetration and reliable fusion. The low hydrogen content (typically under 4ml/100g) is essential for preventing hydrogen-induced cracking (cold cracking) in high-strength carbon and low-alloy steels. Packaged in a robust 6.20 kg tube, these electrodes are protected from moisture absorption, ensuring they remain within specification for critical code work. Proper storage in a holding oven is recommended after opening to maintain low hydrogen status.

FAQ

The '-1' suffix indicates that the electrode meets specific impact toughness requirements at a lower temperature (-45°C / -50°F) compared to standard E7018 electrodes, offering better resistance to brittle fracture.

For a 5.0mm (3/16") E7018 electrode, the recommended amperage range is typically between 200 and 300 amps, depending on the specific manufacturer and position, though 220-275 amps is a common sweet spot.

Yes, E7018-1 are low hydrogen electrodes. Once the hermetically sealed package is opened, they should be stored in a holding oven at 250°F-300°F to prevent moisture absorption which can cause porosity and cracking.

While many E7018 electrodes can run on AC, they are primarily designed for DCEP (DC+). Using DCEP provides the best arc stability, penetration, and bead appearance.

The 18-inch length (compared to the standard 14-inch) allows for longer weld runs, reducing the number of electrode changes and start/stop points, which improves efficiency and weld quality.

A 5.0mm (3/16") rod is generally considered too large for vertical up welding on standard thicknesses due to the large volume of molten metal. It is best suited for flat and horizontal fillets or groove welds.

This electrode is suitable for welding carbon and low-alloy steels, including A36, A516, and A572 grades, particularly where high strength and toughness are required.
