The Choice of Gas When Cutting Carbon Steel with A Fiber Laser Cutting Machine, Remember These Points!

The choice of gas when cutting carbon steel with a fiber laser cutting machine, remember these points!

Fiber laser cutting machines can use different gases when cutting carbon steel, including air, oxygen and nitrogen. 

Choosing the right type of gas is crucial to cutting quality and effect.

This article will introduce the application and difference of different gases in carbon steel cutting to help you choose the right type of gas.

Air cutting

Air cutting is suitable for negative angle cutting, with faster cutting speed and low cost. Due to the low cleanliness of the air, the surface of the cut carbon steel may have burrs.

Therefore, air cutting is mainly suitable for cutting of medium and thin plates.

Oxygen cutting

Oxygen cutting can be used for positive and negative angle cutting of carbon steel plates. Oxygen cutting has good cutting effect and quality, and the cutting section is smooth.

Using equipment with the same power, oxygen cutting can cut thicker carbon steel plates. However, the speed of oxygen cutting is relatively slow.

The speed of oxygen negative angle cutting and positive angle cutting is relatively fast, but it will sacrifice the quality of the cutting section and the cutting section is rough. Therefore, oxygen cutting is suitable for cutting of medium and thick plates.

Nitrogen Cutting

Nitrogen is a more expensive gas and is mainly used for the special needs of local tyrants. Nitrogen is generally not used in carbon steel cutting. Nitrogen cutting is suitable for cutting high-quality sheet metal parts such as stainless steel, aluminum and brass.

When choosing a cutting gas, it is necessary to evaluate it according to the specific material and processing requirements. If you need to cut carbon steel, you can make a choice according to the following guidelines:

For the blanking of medium and thin plates, air cutting is an economical and fast choice, and it is also the most selected method in the process of use.

For the blanking of medium and thick plates, oxygen cutting can provide high-quality and smooth cutting results.

Nitrogen cutting is mainly suitable for high-quality sheet metal materials and is not often used for carbon steel cutting.

The correct choice of gas type can improve the cutting effect and processing quality while reducing costs. Therefore, when using a fiber laser cutting machine to cut carbon steel, it is very important to choose the appropriate gas type according to the specific processing needs.
