O2 N2 Air for fiber laser cutting machine

Firstly, Assist gases includes O2 N2 Air.

its thickness, and the desired edge quality will influece.

The low pressures and high speeds of oxygen make it ideal for cutting mild steel.

while the inert properties of nitrogen provide a clean, precise, oxidation-free cut across all materials.

But beyond these basics, metal fabricators must weigh a number of critical factors in order to choose the right assist gas for the job.

We need to consider Indirect labor costs, desired edge quality, gas expense, and laser power.

Secondely, Influences of O2 as the auxiliary gas on metal laser cutting

O2  will not only blow away the molten metal liquid, but also have an oxidation reaction.

It will promote the endothermic melting of the metal, so as to achieve the melting of thicker metals. This process significantly improves the processing capability of the laser.

Besides, it has quenching effects generated on the material around the cut surface.

It improves the hardness of the metal and has a certain influence on the subsequent processing.

Influences of N2 as the auxiliary gas on metal laser cutting

N2 preventing the material from being oxidized.

so as to ensure the quality of the cut surface.

However, N2 has no oxidation effect to enhance heat transfer, so it does not help to improve cutting ability like O2.

In addition, the nitrogen consumption is relatively larger, which results in an increase in cutting cost compared to the use of other gases.
