CO2 is very important in cutting and welding technology in various industries. This technology is widely used because it is a cost-efficient high-power beam source capable of deeper penetration and higher processing speeds. This working machine emits at 10.6 µm and has electrical efficiencies of approximately 10 to 15 percent. It is a known fact that Lasers are one of the most widely used tools in manufacturing today as they allow engineers to create complex structures, designs, and fine features that are difficult or impossible to make using traditional machining equipment. Laser cuts are super-clean with no burrs or heat effects on the surrounding material, thereby eliminating the need for some secondary finishing steps. Their gas mixture consists mainly of helium to ensure the dissipation of heat but also contains carbon dioxide, the laser-active medium, and nitrogen, in which a gas discharge creates the energy necessary for proper excitation level. To use CO2 in cutting it follows domes factors like the CO2 principle whereby a diffusion-cooled high-power industrial CO2 laser system, in which the slab laser replaces the flowing gas lasers in many applications because of a range of advantages offered by the basic design. The radiofrequency (RF) excitation is also very important in this sector as it functions by transferring electrical energy into the gas and in this, their discharge is perpendicular to the resonator.
Application Of Industrial CO2 Laser
Medicine
Industrial CO2 laser has its application in Medical services just as window optical have been and many medical procedures especially in the area of soft tissue surgery and this is possible because water absorbs this frequency of light. The majority of the body tissues contain water thereby making these surgery procedures safe and possible and they can be used in laser surgery and skin resurfacing, laser facelifts, treatment of various skin conditions, removal of vocal fold lesion, and advanced welding of human tissue.
Industrial CO2 Laser Cutting
CO2 can be used in cutting surfaces to fine shapes, and this works by the use of a focus lens that converges the CO2 laser beam on the material to be cut which in turn produces heat energy. This technology also has a coaxial compressed gas that blows away the material as it melts. Just as industrial lens manufacturers USA have been on forefront Alpine research optics is not left out.
Industrial CO2 Laser Welding
When iron combines with atmospheric nitrogen it becomes brittle but CO2 gas can bridge that effect, therefore, when it is used to shield the weld pool from the atmosphere. CO2 welding is used products with complex geometries or dissimilar materials that are difficult to join together, so this welding can be the best joining process compared to gluing or soldering. It also creates strong, high-precision welds that can be as small as 0.004 inches and the quality of this welding is simply the best. CO2 gas can be decomposed by the ultra−high temperature arc heat into CO and O near the arc there for the, C that is contained in steel is easier to combine with O than Fe deprives O of FeO to generate CO gas. The welding wire Si and Mn that have a stronger affinity with O is used; in this case, O in FeO combines not with C but with Si and Mn and floats upon the surface of the weld pool to form a slag of SiO2 and MnO.
