How nexAir Supports Commercial Divers with Custom Gas Solutions for Underwater Welding

When you’re welding on an oil rig 80 feet below the surface, you need gas mixtures that work as hard as you do. Commercial diving operations handle everything from pipeline repairs to ship hull maintenance, and each project has specific requirements for both breathing and welding gases.

We’ve been mixing custom gases for commercial divers for years, learning what works in real underwater conditions. Whether you’re running dry habitat welding or working in open water, we create gas solutions that support your specific diving and welding requirements.

Breathing Mixes That Match Your Depth

Different depths call for different breathing gas mixtures. For deep commercial work, we mix helium-oxygen blends that keep you sharp and focused. For longer jobs at moderate depths, our nitrox mixtures extend your bottom time while reducing decompression requirements.

Every mixture gets tested thoroughly before it ships. You receive complete analysis sheets showing exactly what’s in each tank: oxygen percentages, helium content, and any other components. Your dive supervisor can use this data for accurate dive planning and decompression calculations.

Welding Gases Built for Wet Work

Underwater welding is a different animal than surface welding. Water changes how heat moves, how arcs behave, and how your weld pool forms. We’ve developed shielding gas mixtures specifically for these conditions, working with experienced underwater welders to get the chemistry right.

Whether you’re doing wet stick welding or working inside a dry habitat, we can adjust gas compositions to match your technique and materials. Our welders tell us these custom mixes help maintain consistent penetration and reduce porosity in challenging underwater conditions.

Getting Gas to Where You Work

Offshore platforms, remote harbors, diving barges—commercial diving happens in places that regular delivery trucks can’t reach. We coordinate with marine transport companies and work around tide schedules to get your gas supplies where you need them.

We also handle the logistics of staging gases at dive bases and coordinating with project schedules. When you’re mobilizing a commercial diving operation, we make sure your gas supply is one less thing to worry about in your project planning.

Real Experience With Commercial Diving

Our team has worked with saturation diving operations, underwater construction projects, and emergency repair situations. We understand how gas supply fits into the bigger picture of commercial diving logistics and safety planning.

When projects get complicated or conditions change, you’re working with people who know diving operations inside and out. This hands-on KnowHow™ helps us solve problems quickly and keep your diving operations moving forward, so you can Forge Forward with confidence knowing your gas supply is handled by people who understand what you’re doing down there.
