Nitrogen Generator for Laser Cutting is a technology that uses a laser to cut through a wide variety of materials such as metal, resulting in a cut edge. It is the appropriate method particularly when high precision or speed is required.

Why Use Nitrogen Generator for Laser Cutting?

Nitrogen Generator for Laser Cutting is an excellent way to reduce costs and improve efficiency, nitrogen serves as a flushing and cutting gas that is blown through the kerf at high pressure. As an inert gas, nitrogen does not react with the molten metal and prevents the cutting edge from coming into contact with oxygen. This prevents oxidation and rust formation at the cutting edges. As a result, nitrogen cutting can help you save money on finishing processes, which can require machinery that is expensive to purchase and maintain.

Oxygen vs. Nitrogen

Oxygen performs a very different role in laser cutting. Whereas nitrogen ensures no reaction takes place at the cutting site, oxygen reacts with the metal in an exothermic reaction. That means more heat is produced around the cutting site, speeding up the cutting process.

The downside is that oxidation causes damage to the cut edge, which means a further clean-up process is required. You can use manual grinding, chemical removal, or other methods to finish the edge. In contrast, nitrogen cutting produces a clean edge.

Depending on the gas delivery method used, nitrogen cutting can be more expensive per hour than oxygen, so you might find it more cost-effective to use oxygen if you are cutting very thick steel.

Why use Oxysystems for Nitrogen Generators?

Using a nitrogen generator for laser cutting reduces costs. Regularly ordering nitrogen liquid is not only inconvenient but also expensive. With our excellent purity of 99.999% and no oil in the high-pressure outlet, there is no reason why continuing using liquid. With our nitrogen generators, we supply high-quality solutions for the stationary and mobile production of nitrogen for different applications, including low-volume requirements.

Laser Cutting Mild Steel with Nitrogen

Nitrogen laser cutting is suitable for shaping mild steel, although other factors affect the decision. Using nitrogen provides the most benefit when you are cutting very thin material. If the steel is thicker than 1/8 in, the cutting speed is similar for both nitrogen and oxygen.

Plasma Cutting Aluminium with Nitrogen

Using nitrogen can produce excellent edge quality when cutting aluminium. By reducing oxidation by using nitrogen when cutting aluminium, you can reduce the costs of processing the metal after cutting to improve edge quality. More on laser cutting.
