Cutting and welding sheet metal through the laser process requires gases and mixtures of high purity and production precision. Nippon Gases, through decades of experience in the production of gas,and in collaboration with the best manufacturers of laser systems, has developed production techniques capable of meeting the strictest requirements of manufacturers and beyond.
CO2 have a responsibility to create light emission for effect of energy excitation, that after polarisation, became laser beam.
The job of this gas is double, it is used to blow the molten metal out of the kerf and supports the CO2 laser as a resonator auxiliary gas in raising the energy level of the CO2 molecules.
Used into the laser source, the effect is to maintain system cooled.
For laser cutting of unalloyed steel, oxygen is necessary for the oxidation of the heated metal in the kerf, the gas also blows the molten and oxidised metal out of the kerf.
Carbon steel, stainless steel, aluminum, titanium and many others have metallurgical different characteristics and a reactivity towards air.
During the laser cutting or welding phases it is essential to protect or bring heat to allow the process, while the absence of pollutants allows to exploit all the power of the laser sources, whether CO2 or fiber.
The laser cutting process is also a very effective production process thanks to the use of high-quality gases and usually requires almost no supplementary machining (e.g. drilling) or post-processing (e.g. grinding). With CO2 lasers, the quality of the resonator gases is also quite decisive for the service life and effectiveness of the laser source.
To supply gas to a laser cutting system it is essential to know fluid dynamics. In fact, it is essential to guarantee high flow rates at high pressures without affecting the machine with pressure changes.
It is equally important to maintain the purity of the gases contained in the containers up to the point of use. In this case too, the experience and passion that distinguishes Nippon Gases have allowed us to design specific equipment for gas management.
In Nippon Gases we have developed various qualities of gases to adapt to your applications. Call us or write to us and we will help you get the most out of it.
