Laser slicing with inert gasses takes much less vitality than laser chopping with reactive gasses. Since this process relies on a chemical reaction, the molten steel oxide that is not expelled by the oxygen jet varieties alongside the edge of the cut. A crucial laser line power and laser speed mixture is needed so as to get a high quality edge when it comes to its geometry. The welding parameters used, in addition to the sort of steels and lasers used, affect the effect. The surface coating on the sheet steels has an influence on the chopping process due to its impact on the chemical composition and melting point. The greatest laser beam focus position was found under the sheet surface. Better high quality cuts and quick slicing speeds were produced by using lens. It was good that it may ...
