How To Choose The Gas When Cutting? What Are The Characteristics Of Various Gases

In the process of laser cutting, the choice of gas is crucial, and different gases have their own characteristics and advantages. Common cutting gases include air, nitrogen and oxygen. Their features and application scenarios are described in detail below.
1.Air cutting
Air is an economical cutting gas, and the cutting speed is the fastest of the three, suitable for a variety of materials. However, for thicker plates, the air cutting effect is not good, and it is easy to produce burrs.
2.Oxygen cutting
Oxygen is suitable for occasions where the quality of the cutting surface is high and the burr free effect is required. Although the oxygen cutting speed is slower, but its cutting surface quality is excellent.
3.Nitrogen cutting
Because nitrogen does not support combustion, it can effectively reduce the oxidation and burning of the material surface, especially suitable for stainless steel cutting, and can maintain the stainless edge. However, nitrogen is relatively expensive and usually requires a nitrogen maker.
The above is a brief introduction to the three commonly used laser cutting gases, hoping to help you choose the most suitable cutting gas.
