OVERVIEW

Professional Grade Underwater Welding Electrodes

For marine contractors, commercial divers, and offshore maintenance crews, the Arcair Sea-Weld 3/16" x 18" electrode is a premier choice for wet welding applications. Designed to tackle the unique challenges of the underwater environment, these electrodes are engineered to provide structural integrity and ease of use when performing repairs on ship hulls, piers, pilings, and offshore platforms. The Sea-Weld series is recognized for its ability to produce consistent, high-quality welds even when fully submerged, making it a staple in the inventory of professional salvage and marine construction teams.

The key to the Sea-Weld's performance lies in its specialized waterproof coating. Unlike standard welding rods that would disintegrate or fail to arc in water, the Arcair Sea-Weld features a robust flux coating that resists moisture ingress and protects the core wire. This ensures that the diver can strike and maintain a stable arc immediately, without fighting the equipment. The 3/16-inch diameter allows for significant metal deposition, while the 18-inch length helps maximize bottom time by reducing the frequency of electrode changes—a critical factor when working at depth.

Packaged in a quantity of 75, these electrodes are ready for deployment on substantial projects. Whether you are repairing a sheet pile wall or performing emergency hull maintenance, Arcair Sea-Weld provides the reliability required for critical infrastructure work. Josef Gas supplies these specialized consumables to ensure your diving operations have access to the best tools for the job.

FAQ

Arcair Sea-Weld electrodes are typically designed to operate on DC Straight Polarity (DCEN - Electrode Negative). This polarity is standard for wet welding as it helps protect the electrode holder and diver while providing good penetration.

While they will deposit metal on the surface, they are specifically formulated for the rapid cooling rates and pressure of underwater environments. Using them on the surface is not recommended as standard electrodes are far more cost-effective and better suited for air welding.

Arcair Sea-Weld electrodes are designed to meet the requirements of AWS D3.6 for Class B underwater welds, which covers welds intended for less critical structural applications where high ductility is not the primary concern.

This specific SKU (42034007) comes as a package of 75 electrodes.

Yes, for safety and performance, these should be used with a dedicated underwater electrode holder (stinger) designed to fully insulate the electrode and prevent electrical shock to the diver.

The 18-inch length is longer than standard 14-inch welding rods, allowing the diver to weld for longer periods before needing to stop and change the electrode, which improves efficiency underwater.

Yes, the Sea-Weld electrodes feature a proprietary waterproof coating that protects the flux and core wire from water absorption, ensuring the rod remains functional even after being submerged.

These electrodes are designed for welding mild steel and low-alloy steels commonly found in marine structures like sheet piles, ship hulls, and platforms.
