Fiber Laser Cutting Metal Techniques | IPG Photonics
Laser Cutting Techniques. In Fusion Cutting, the laser beam is coaxially combined with an inert gas such as nitrogen or argon. The heat produced by the laser beam creates a molten layer that is ejected down through the kerf by pressurized gas from the nozzle. Fusion cutting may be used for cutting mild steels up to 25 mm thick.
