What gases are needed for metal laser cutting machines?
Metal laser cutting machine is a common metal cutting equipment. When using this equipment, you need to choose different auxiliary gas according to different cutting materials. Let us briefly understand what is needed for metal laser cutting machine. Gas, let's see... What gases are required for metal laser cutting machines: At present, the auxiliary gases commonly used in metal laser cutting machines are oxygen, nitrogen, air and argon. 1. When laser cutting, a large amount of heat is generated. When such high heat is concentrated together, the material at the cutting portion is burned, an oxidation reaction occurs, and the workpiece is easily deformed. Therefore, we need to add some auxiliary gases, commonly used are oxygen, air, nitrogen. Second, when we need to process stainless steel, we should choose nitrogen. Because nitrogen can prevent the oxidation of the incision, the processed incision will not be black. Choose high purity when choosing nit...
