Nitrogen Nitrogen is a colorless, odorless, and inert gas that is commonly used as an assist gas in laser cutting and engraving applications. Nitrogen is preferred for laser cutting of stainless steel, aluminum, and other metals because it does not react with the material and produces clean, oxide-free edges without discoloration or contamination.
In laser engraving, nitrogen can be used to assist with the removal of debris and fumes generated during the engraving process, resulting in crisp, high-contrast engravings with minimal residue. Nitrogen gas is supplied to the laser processing area through a nozzle or delivery system, where it interacts with the laser beam to enhance cutting and engraving performance. Proper control and management of nitrogen flow are essential for achieving optimal results and maximizing process efficiency in laser-based manufacturing and fabrication. |
