42034007 - Arcair Sea-Weld 3/16" x 18" Underwater Wet Welding Electrodes (75 Pack)

Arcair Sea-Weld: Superior Wet Welding Performance

The Arcair Sea-Weld 3/16" x 18" Underwater Electrode (SKU: 42034007) sets the standard for wet welding consumables. Engineered by the experts at Arcair, a leader in air carbon-arc and underwater cutting/welding technologies, this electrode is formulated to meet the rigorous demands of commercial diving. It is specifically designed to meet AWS D3.6 specifications for Class B underwater welds, ensuring that repairs made in the wet environment possess the necessary mechanical properties and soundness required for structural applications.

Optimized for the Diver

Underwater welding is physically demanding and technically challenging. The Sea-Weld electrode addresses these difficulties with a user-friendly formulation. It operates on DC Straight Polarity (DCEN), which is the preferred polarity for wet welding safety and electrode life. The arc characteristics are smooth and stable, minimizing spatter and improving visibility in turbid water. Furthermore, the slag system is designed for easy removal. In underwater scenarios, tenacious slag can hide defects or require excessive chipping time; Sea-Weld's slag often lifts easily, leaving a clean bead profile that inspires confidence.

Technical Specifications

This package contains 75 electrodes, each measuring 18 inches in length with a 3/16-inch diameter. The extended length is particularly advantageous for divers, allowing for longer run times per rod. The all-position capability means the electrode can be used for vertical, overhead, and flat welding, providing versatility for complex joint configurations found on subsea structures. The proprietary coating not only insulates the rod electrically but also creates a gaseous shield that protects the molten weld pool from the surrounding water, reducing porosity and hydrogen embrittlement risks associated with wet welding.

• Stable Arc: Easy starting and maintenance of the arc in wet conditions.
• Bead Quality: Excellent contour with minimal undercut.
• Durability: Waterproof coating withstands immersion without breaking down.
