OVERVIEW

Premium Low-Hydrogen E7018-1 Electrodes for Critical Applications

The Bohler E7018-1 Stick Electrode (4.0mm) is a high-performance, basic-coated welding rod designed for the most demanding structural and industrial applications. Engineered to deliver exceptional mechanical properties, this electrode meets the AWS E7018-1 classification, ensuring superior impact toughness even at temperatures as low as -45°C. This makes it the preferred choice for offshore construction, pressure vessel fabrication, and heavy structural steel projects where weld integrity is paramount.

Packaged in a convenient 6.2kg tube, these 18-inch (450mm) electrodes are optimized for efficiency and reduced downtime. The 4.0mm (5/32") diameter allows for higher current carrying capacity and deposition rates, making it ideal for filling larger joints and welding thicker plate sections. The coating is formulated to resist moisture absorption, maintaining low diffusible hydrogen levels (H4 or H8) to prevent cold cracking and ensure X-ray quality welds.

Welders will appreciate the smooth, stable arc and excellent puddle control offered by this electrode. It performs exceptionally well in all positions, including vertical-up, providing a flat to slightly convex bead profile with fine ripples. Slag removal is easy, often self-releasing, which reduces post-weld cleanup time. Whether you are welding fine-grained carbon steels or high-strength low-alloy steels, the Bohler E7018-1 provides the reliability and consistency required for code-compliant work.

FAQ

The '-1' suffix indicates that the electrode has been tested for improved impact toughness at lower temperatures. E7018-1 electrodes must meet specific Charpy V-Notch impact requirements at -45°C, whereas standard E7018 is tested at -30°C.

For a 4.0mm (5/32") E7018-1 electrode, the recommended amperage range is typically between 135 and 220 Amps, depending on the welding position and base metal thickness.

Yes, E7018-1 is a low-hydrogen electrode. Once the hermetically sealed package is opened, they should be stored in a holding oven at 120°C-150°C to prevent moisture absorption. If exposed to air for too long, they must be re-dried according to the manufacturer's specifications.

Yes, these Bohler E7018-1 electrodes are designed to operate on both AC (Alternating Current) and DCEP (Direct Current Electrode Positive).

These 4.0mm electrodes are 18 inches (450mm) long, which is longer than the standard 14-inch rods found in smaller diameters, allowing for longer weld runs.

While E7018-1 rods are high-quality, they are low-hydrogen electrodes and generally require cleaner base metal than cellulosic rods like E6010. It is best to clean oil, rust, and paint from the weld area for optimal results.

This specific package contains 6.2kg (approximately 13.6 lbs) of electrodes.
