What gases do carbon steel laser cutting machines need？

1. Air

Air can be supplied directly by an air compressor, so it is very cheap compared to other gases. Although the air contains about 20% oxygen, the cutting efficiency is far less than that of oxygen, and the cutting capacity is similar to that of nitrogen. The main applicable materials are aluminum, aluminum alloy, stainless copper, brass, plated steel, non-metal and so on.

2. Nitrogen

When some metals are cut with oxygen, an oxide film will be formed on the cutting surface, and nitrogen can be used for non-oxidative cutting to prevent the appearance of the oxide film. The main applicable plates are stainless steel, electroplated steel plate, brass, aluminum, aluminum alloy, etc.

3. Oxygen

Mainly used for laser cutting machine to cut carbon steel. While using the oxygen reaction heat to greatly improve the cutting efficiency, the generated oxide film will improve the beam spectral absorption factor of the reflective material. The end face of the incision is black or dark yellow. Mainly applicable to rolled steel, rolled steel for welding structure, carbon steel for mechanical structure, high tension plate, tool plate, stainless steel, electroplated steel plate, copper, copper alloy, etc.
