Laser Cutting

Assist gas is absolutely essential to the performance of the laser - and nitrogen is the assist gas of choice when the cut must be excellent.

What is Laser Cutting?

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:

  • Reducing discoloration of the cut edge
  • Establishing a barrier between atmospheric oxygen and the heated metal edge
  • Assisting in heat dissipation, so the cut edge will cool faster
  • Laser Cutting & On-Site Nitrogen Generation at Breffini Air

    Breffini Air, a ventilation company in Ireland, uses nitrogen as their assist gas in their fiber laser cutting application. On-site nitrogen generation from Atlas Copco makes it happen!
