High-pressure Nitrogen assist gas (20 to 25 bar) blows molten metal out of the kerf without chemical oxidation, leaving bright, weld-ready edges on stainless steel and aluminum.
Mathematical Formula Breakdown
Total Gas Cost = (Cut Time Minutes / 60) × Nitrogen Flow Rate (cu.ft/hr) × $/cu.ft.
Industry Pricing Benchmarks
Nitrogen assist gas represents 35%–50% of total laser operation costs on thick stainless. Liquid nitrogen bulk Dewars average $0.10–$0.22 per 100 cu.ft.
Optimization Strategies
- Install on-site Nitrogen Generation plants (PSA membrane) to eliminate liquid dewar delivery fees and reduce gas costs by 65%.
- Optimize nozzle gap height (0.5–1.0mm) to reduce gas blowing waste around the kerf.
Frequently Asked Questions
Why use Nitrogen instead of Oxygen for laser cutting stainless steel?
Nitrogen prevents edge oxidation, eliminating secondary grinding prior to welding or powder coating.
