Nitrogen versus oxygen in fiber laser cutting
Compare assist gases for cut quality, oxidation and operating cost.
Choosing the right solution for nitrogen versus oxygen in fiber laser cutting requires evaluating materials, production goals and operating conditions together. This guide outlines the main questions to consider before requesting a quotation.
What does assist gas do?
Assist gas helps remove molten material from the kerf. Gas selection should reflect the material and the required edge quality.
Differences between nitrogen and oxygen
Nitrogen is often selected to limit oxidation in suitable applications. Oxygen can contribute reaction heat when cutting certain steels but may leave an oxide layer on the edge.
How to assess total cost
Consider gas consumption, pressure requirements, cutting speed, burrs and downstream welding or painting. The cheapest gas does not always produce the lowest part cost.
