Because of its high gas flow rate, the double-layer nozzle is generally used for high-speed cutting, and the single-layer laser nozzle is used for melting cutting, which uses nitrogen as an auxiliary gas.
The nozzle is a very common loss on the laser cutting machine, but also a very important part of the laser cutting, it is located at the bottom of the laser head, very close to the workpiece, so it plays a very key role in the cutting process.
