Air plays an indispensable role in sheet metal laser cutting. The air itself exists in the atmosphere. It is compressed to the air storage tank by the air compressor, and then filtered, cooled and dried to remove the water and oil in the air before use.

Since the air contains about 21% oxygen, it can make up for the shortage of oxygen and nitrogen to some extent. Air can be used for stainless steel cutting, carbon steel cutting, aluminum plate cutting, etc.

Carbon Steel Plate

For carbon steel plate, when air is used as auxiliary gas for cutting, the part section will produce small burr, but the burr is not sharp, which can be applied to parts with low requirements for burr.

Stainless Steel Plate

When the stainless steel plate is cut by air, the material will be oxidized on the cutting surface after processing. When the cutting section is welded, the oxide will produce defects such as slag inclusion and air hole in the weld bead, which will affect the weld quality, and then cause the strength of the welding part to decline.

Therefore, when the parts are cut with air and then welded, it is necessary to polish the oxide layer on the section of the welding part to improve the welding quality.

In addition, after cutting, the section will oxidize and produce yellow oxide layer, which will affect if the part is an appearance part. The oxide layer will also have an impact on welding. The oxide layer must be polished before welding.

Aluminum Plate And Aluminum Alloy Plate

For aluminum plate and aluminum alloy plate, using air as auxiliary gas can reduce the cutting burr. If nitrogen is used, the cutting burr will be larger.

20000W Air Cutting 14mm Carbon Steel

The 20000 watt air cutting is suitable for cutting carbon steel plates below 20 mm. Taking 14 mm carbon steel plates as an example, the cutting efficiency is at least twice that of oxygen, and there is almost no burr at the bottom of the cutting.

Cutting Data And Effect

From the perspective of cutting speed and effect, for customers pursuing processing efficiency, using air as auxiliary gas is a wise choice with high cost performance, which can not only help customers save processing costs, but also optimize the cutting process.

Correct Use Of Air Cutting To Reduce Production Costs

In the current increasingly competitive environment of the industry, it is one of the means to gain competitive advantage to increase the added value of products by improving the difficulty of product technology and the level of industrial design.

Saving processing costs under the existing process conditions is also an effective way to gain competitive advantage. Selecting the right power and materials, and using air as auxiliary gas for material cutting can reduce cutting costs, bring more profits to enterprises, and provide more help for enterprise transformation and upgrading.
