LASAL™ gases
Laser cutting and welding to improve productivity and lower operating costs
| LASAL™ 2001 |
| nitrogen / N50 purity / 99.999% |
| For laser cutting of stainless steel an inert gas (nitrogen) is applied. For the best cutting quality, with no further edge processing (e.g. before welding), a high-quality nitrogen should be used. Air Liquide has developed LASAL™ 2001: a quality-controlled nitrogen, dedicated for cutting of stainless steels under high pressure. Like for all other LASAL™ gases, LASAL™ 2001 quality is controlled during production, filling and delivery. Currently LASAL™ 2001 is also applied for highly efficient cutting of small thicknesses (up to 6 mm) carbon steel. Please see on the videos on the right the comparison of 3mm and 5mm carbon steel cutting with oxygen and nitrogen. |
| LASAL™ 2003 |
| oxygen / N35 purity / 99.95% |
| For laser cutting of carbon steel usually oxygen is used, taking advantage of cutting exothermic reaction with iron. Depending on the source of origin, industrial oxygen can have a variable quality. Studies carried out by own technical centers have enabled Air Liquide to recognize all the impurities affecting the cutting process. Therefore, Air Liquide has developed LASAL™ 2003: a quality-controlled oxygen, dedicated for laser cutting of carbon steels. Compared to the industrial oxygen, LASAL™ 2003 enables to gain 10-40% in cutting speed while ensuring better quality of cut edges. |
