What is the difference between single-layer Laser Cutting Nozzle and double-layer Laser Cutting Nozzle
Posted on:

The difference between single-layer Laser Cutting Nozzle and laser double-layer Laser Cutting Nozzle:
Single-layer Laser Cutting Nozzle is used for melting cutting, that is, using nitrogen as auxiliary gas, cutting stainless steel and aluminum plates, etc., using a single-layer laser nozzle with a specification of 1.4-3.0mm.
Double-layer Laser Cutting Nozzle is generally used for oxidative cutting, that is, using oxygen as an auxiliary gas for cutting carbon steel, using a double-layer laser nozzle with a specification of 1.5-3.0.
For single-layer Laser Cutting Nozzle, in daily production, the most widely used three types of Laser Cutting Nozzle: Among them, the most widely used is the conical nozzle, which has the advantages of good cutting quality and high cutting precision. It is generally used for nitrogen cutting stainless steel, or fine cutting with high precision and high surface requirements.
The double-layer Laser Cutting Nozzle on the market is actually a simplified version of the supersonic nozzle researched in the laboratory. After the gas passes through the inner core, it will undergo secondary expansion to increase the gas velocity, and then pass through the end hole to reach the working surface.
