Nitrogen generators for metal fabrication & surface treatments
Nitrogen generators are essential in modern metal fabrication, serving as a reliable, on-demand source of high-purity nitrogen for critical processes that demand an oxygen-free environment.
By enabling on-site production, PEAK Gas i-Flow nitrogen generators replace costly, outdated methods of delivered nitrogen supply with an autonomous, scalable solution.
What is metal fabrication?
Metal fabrication is the creation of metal structures, parts, and machines from raw metal materials through cutting, bending, forming and assembling processes. It transforms raw materials into finished products for core industries like construction, automotive and aerospace through techniques like cutting (laser, plasma, waterjet), bending (press brakes), machining, stamping, and welding.
How is nitrogen used in metal fabrication?
Nitrogen gas is used in metal fabrication and surface tratments primarily as an inert shielding gas, preventing oxidation, decarburization, and discoloration at high temperatures.
Nitrogen in metal fabrication, heat treatments & processing
Key Applications of Nitrogen Include:
· Laser cutting: high-pressure N2 gas acts as an assist gas, protecting the cut edge from oxidation, ensuring a clean, dross-free edge.
· Heat treatments: Nitrogen creates an inert atmosphere in furnaces to prevent oxidation, and is used for sintering (bonding metal powders) and bright annealing.
· Purging & Inerting: Nitrogen is often used to purge hazardous gases from furnaces before heat treatment and to purge oxygen from furnaces during the process.
· Welding: Nitrogen acts as a shielding gas to prevent porosity and oxidation during arc welding of steel, stainless steel, and titanium.
· Degassing: Used to remove impurities like hydrogen from molten metal
Why choose a nitrogen generator for metal fabrication?
Choosing an on-site nitrogen generator for metal fabrication eliminates the costs and logistical hurdles of bottled or bulk N2 supply. Continuous, reliable supply of nitrogen gas reduces reliance on external supplier delivery shortages or late deliveries.
Enhanced quality & precision
Ensure clean precise cuts on stainless steel and aluminium, removing the need for secondary finishing
Cost savings
Companies often see a return in their investment within a couple of years as the cost per unit of nitrogen becomes significantly lower compared to delivered gas
Reliable and customizable supply
Reduce waste and unlock the option to expand your capacity to meet future needs with a reliable nitrogen generator
Enhanced safety
Eliminate manual handling of pressurized gas cylinders
