N₂ shield gas prevents oxidation on stainless steel, aluminum, and titanium. Eliminates post-weld cleaning, increases welding speed, and reduces gas costs by 50–70%.
N₂ displaces oxygen at the weld puddle, preventing oxide formation on stainless steel, aluminum, and titanium. Results in cleaner, stronger welds with no discoloration.
Nitrogen shielding enables 15–25% faster welding speeds compared to argon or mixed gases. Higher throughput per operator shift without compromising weld quality.
On-site N₂ generation: $0.15–0.25/Nm³ vs. $0.50+ for bottled argon or mixed gases. Payback typically 6–8 months for a dedicated welding station.
PSA nitrogen generators deliver ±0.1% purity stability. Built-in O₂ analyzer with real-time display ensures shield gas quality is always within spec.
