Fiber laser cutting machine auxiliary gas

First of all, what is the role of fiber laser cutting machine auxiliary gas?Why do fiber laser cutting machines use auxiliary gases?

There are four reasons

Firstly the ability to chemically react the auxiliary gas with the metal material, increasing its strength.

Secondlyy to help the equipment to blow off the slag cutting area, clean the slit.

Thirdly to reduce the size of the heat-affected zone through the adjacent areas of the cooling joint.

Fourthly to protect the focal length lens and prevent the optical lens from being polluted by combustion products.

What are the commonly used auxiliary gases for fiber laser cutting machine?Can air be used as an auxiliary gas?

Laser cutting experts tell you, fiber laser cutting machine in cutting metal sheet, you can choose nitrogen, oxygen, air these three types of gas as an auxiliary gas.

Their functions are as follows:

N:

When cutting stainless steel, aluminum and other color plates, nitrogen is used as an auxiliary gas cooling and protection material.When cutting metal section, it is relatively bright and the effect is good.

Oxygen:

When cutting carbon steel, you can use oxygen, because oxygen has cooling and accelerated combustion, can accelerate the cutting.The cutting speed is the fastest of all gases.

Air:

To save costs, air is used to cut stainless steel, but with fine burrs on the back.Just sand it down with sandpaper.This means that fiber laser cutters can choose air as an auxiliary gas when cutting certain materials.And in the use of air to choose air compressor.

But laser cutting experts suggest, for example, a 1000 watt fiber laser cutting machine.1mm of carbon steel and stainless steel is best cut with nitrogen or air, the effect will be better.Oxygen burns the edges, which is not ideal.

I hope it helps you.If you have any questions about the machine, please feel free to contact XT Laser.
