The choice of auxiliary gas laser cutting machine

How to choose the gas laser cutting machine laser cutting machine can use main auxiliary gas of oxygen, nitrogen, air and argon these, here we according to different auxiliary gas, as an introduction to the purpose and characteristics of the used only for your reference. 1, oxygen is mainly used for laser cutting machine for cutting the carbon steel. Use oxygen heat of reaction of large-format improve cutting efficiency at the same time, the oxide film can improve the beam spectrum absorption factor of reflective materials. Incision face black or dark yellow. Mainly suitable for rolling steel, dissolves in rolling steel structure, mechanical structure with carbon steel, high tension, palette, stainless steel, galvanized steel, copper, copper alloy, etc. 2, nitrogen when some metal cutting using oxygen oxidation film formed on the surface of the cutting, using nitrogen gas to prevent the occurrence of the oxide film could be without oxidation cutting. No cut surface oxide can be welding, direct daub, strong corrosion resistance, etc. Incision face pale. Main applicable plates are stainless steel, galvanized steel, brass, aluminum, aluminum alloy, etc. 3, air can be provided directly by the air compressor, so the price is very cheap compared with other gases. Although containing about 20% of the oxygen in the air, but the cutting efficiency is much less oxygen, cutting ability similar to nitrogen. Cut surface will appear trace oxide film, but can be used as measures to prevent a coating layer falls off. Incision face yellow. Main applicable materials are aluminum, aluminum alloy, stainless copper, brass, galvanized steel, nonmetal and so on. 4, argon gas argon as inert gas, used to prevent oxidation in laser cutting machine for cutting and nitride, also used in the welding, compared with other processing gas, japonica rice price, increase the cost. Incision face pale.
