What auxiliary gas can be used laser cutting?

Laser cutting machine can use the auxiliary gas when cutting, mainly oxygen, nitrogen, air and argon, and the following we will introduce its use and characteristics for different auxiliary gases.

1.Atmosphere

Air can be supplied directly from the air compressor, so the price is very cheap compared with other gases. Although the air contains about 20% of the oxygen, but the cutting efficiency is far less than oxygen, cutting capacity and nitrogen. The cutting surface will appear micro film, but it can be used as a measure to prevent the film from falling off. Cut end face yellow.
The material is mainly applicable to aluminum, aluminum alloy, stainless steel, brass, galvanized steel, non metal and so on.

2.Nitrogen

Some times,when we cut some metal material,the cutting surface will form oxide film,adopt nitrogen can invoide the oxide film.The non oxidation cutting mask has the characteristics of direct welding, coating, corrosion resistance and so on. Cut face is white.
The main application of the plate are stainless steel, galvanized steel, brass, aluminum, aluminum alloy, etc.

3.Oxygen

Mainly used for cutting carbon steel in laser cutting machine. Using oxygen reaction heat large format improve cutting efficiency at the same time, resulting in the oxide film can improve the reflective material beam spectrum absorption factor. Cut face is black or dark yellow.
Is mainly used for rolling steel, solution and connecting structure of rolled steel, mechanical structure with carbon steel, high tension version, tools in, stainless steel, galvanized steel, copper and copper alloys.

4.Argon

Argon is inert gas, used in the laser cutting machine to prevent oxidation and nitriding, also used in welding, compared with other processing gas, the price of Japonica rice, the corresponding increase in cost. Cut face is white.
