How Assist Gas Technology is Advancing Laser Cutting

As highlighted by The Fabricator in their article, “Laser Cutting Assist Gas Technology Evolves,”, fiber laser cutting technology relies not only on laser power but also on assist gases to optimize the cutting process. Traditionally, oxygen was the primary assist gas for cutting mild steel, but many fabricators have transitioned to nitrogen, which prevents oxidation and produces cleaner cuts.

While nitrogen offers advantages, it also has high consumption rates and can create narrow kerfs in thick materials, making part removal difficult. To address these challenges, advancements in gas mixing and nozzle technology are helping fabricators reduce gas usage while improving cut quality and efficiency. Some systems, like those from Mitsubishi Laser, now integrate gas flow optimization directly into the nozzle, ensuring better performance and cost efficiency.
