Fiber laser cutting with nitrogen. Utilising our knowledge of laser cutting our nitrogen generation systems are tailored to the exact needs of individual clients providing pure high pressure gas on demand. Fiber laser cutting systems can certainly cut up to one inch thick with higher fiber laser powers and even cut faster when utilizing nitrogen as the assist gas but the sweet spot where the most significant benefits are realized is in the 516 inch and under range for steel when making comparisons with co2 systems. Their functions are as following respectively. The two most common types of laser cutting machines are fiber laser and co 2. In some cases higher laser powers where nitrogen is employed in cutting thin steel allow the laser user to expect processing speeds three times to four times faster than what can be achieved when using oxygen. Material in co 2 may call for a 25 mm diameter nozzle. In this mechanical process gas flows through the fibers with the oxygen permeating outward through pores in the fiber and nitrogen molecules which cant fit through the pores and flowing through to the laser. Laser light amplification by stimulated emission of radiation cutting is a technology that uses light to cut various materials through a process of optical amplification based on the stimulated emission of electromagnetic radiationsome industrial applications for cutting metals are with co 2 laser and fiber laser cutting equipment. Nitrogen is used for cutting nonferrrous metal such as stainless steel and aluminum sheet which can cool and protect the material. Nitrogen generators typically rely on one of two technologies to generate pure nitrogen. Your co2 laser may have been limited to cutting mild steel with nitrogen assist gas at 316 inch thick or 7 gauge material. But because in a fiber laser cutting situation the kerf is usually narrower the application may require a 3 mm diameter nozzle. Using a wider nozzle diameter seems to benefit a nitrogen cutting operation with a fiber system. Co 2 lasers use an electromagnetically stimulated gastypically a mixture of carbon dioxide nitrogen and sometimes hydrogen xenon or heliumas their active laser medium. Hollow fiber membranes.

Nitrogen is used as a high pressure gas assist for cutting. In contrast fiber laserswhich are a type of solid state laseruse an optical fiber. With fiber technologys availability of much higher wattage ratings than co2 laser cutting machines you can now process materials that previously had to be cut with oxygen. Normally o2 oxygen n nitrogen and air will be used as auxiliary gas for fiber laser cutting.
