The functions of the auxiliary gases in laser cutting are aiding combustion, blowing away molten materials from the cut, preventing oxidation, and protecting components like the focusing lens. Do you know what auxiliary gases are commonly used for laser cutting machines? The main auxiliary gases are Oxygen (O2), Nitrogen (N2), Inert Gases and Air. Oxygen can be considered for cutting carbon steel, low-alloy steel materials, thick plates, or when cutting quality and surface requirements are not strict. Nitrogen is a widely used gas in laser cutting, which is commonly used in cutting stainless steel, aluminum alloys and copper alloys. Inert gases are typically used for cutting special materials like titanium alloys and copper. Air has a wide range of applications and can be used for cutting both metal materials (such as carbon steel, stainless steel, aluminum alloys, etc.) and non-metal materials (like wood, acrylic).
