61883200 - Bonarc E7018 Low Hydrogen Stick Electrode 3.2mm

Premium Bonarc 7018 Low Hydrogen Electrodes

The Bonarc 7018 3.2mm Stick Electrode is a high-performance consumable designed for the Shielded Metal Arc Welding (SMAW) process. Engineered for professional industrial applications, this electrode features a low hydrogen, iron powder coating that delivers exceptional weld quality on mild and low-alloy steels. It is the go-to choice for fabricators requiring X-ray quality welds with superior mechanical properties, particularly in structural applications where joint integrity is critical.

One of the standout features of the Bonarc 7018 is its excellent operator appeal. The electrode strikes and re-strikes easily, maintaining a stable arc that is easy to control in all positions. The addition of iron powder to the coating not only improves the deposition rate but also assists in producing a smooth, uniform bead profile with minimal spatter. Slag removal is often self-releasing or requires minimal chipping, which significantly improves productivity during multi-pass welding operations.

This electrode is classified as E7018 by the American Welding Society (AWS), indicating a minimum tensile strength of 70,000 psi. It is specifically formulated to resist moisture absorption, although proper storage in a rod oven is recommended to maintain its low hydrogen status. The Bonarc 7018 is versatile enough to be used with both DC+ (Reverse Polarity) and AC power sources, making it compatible with a wide range of welding machines found in workshops and field sites.

Industrial Reliability

For industries ranging from construction to shipbuilding, the Bonarc 7018 provides the reliability needed for critical joints. Its ability to produce crack-resistant welds on difficult-to-weld steels makes it an essential inventory item for maintenance and repair operations (MRO). Whether you are welding heavy I-beams, pressure vessels, or machinery frames, this 3.2mm electrode offers the penetration and strength required for heavy-duty tasks.
