Laser Cutting Overview
At it's simplest, laser cutting is the process by which metals (including aluminum, stainless steel, and carbon steel) are cut with a high-powered laser beam. An essential element in this process is assist gas, which is the gas that is used in the cutting process to ensure the quality performance of the laser.
Nitrogen in Laser Cutting
Nitrogen is the most common assist gas used when the cut of the laser must be excellent. The process vaporizes the metal, and before the vaporized metal can resolidify, the nitrogen gas moves it away from the cut edge. Nitrogen is also essential in:
