The industries now prefer laser more than the traditional method of cutting sheet because of its flexibility, quality, and productivity.
FREMONT, CA: Today laser is efficiently used in a wide range of applications, where the source of energy is a laser that concentrates on the optical strength of the surface that has to be processed. The energy with high-density will melt and vaporize a small fraction of the surfaces where it engraves, in a controlled manner for attaining the desired result. In the industrial sector, there is the extensive usage of laser in cutting operations on the materials that can be non-metallic, metallic, and even composites.
Laser Cutting in Short
In recent times, laser cutting has become an essential procedure in the sheet metal cutting to the extent that it has outshined the use of traditional technologies. It is a process that requires concentrated energy beams and is contemplated to be a technique that generates thermal separation. The thermal separation occurs because of the heating and fast melting of the surface that gets hit by the laser beam, and once it penetrated the material, it cuts through the handling of the beam, sheet metal, or both of them. Furthermore, the cutting can be done in any geometrical figure according to the wish of the cutter. It is necessary to remove the melted and vaporized material from the cutting surface in the form of gas flow that exits coaxially from the laser beam and directly influences the cleanliness and quality of the cutting. Laser cutting increases efficiency and is also economical. Therefore, in comparison with the traditional sheet metal cutting technology and laser technology, the later has more advantages because of its speed, accuracy, and also the quality if the process along with the low cost.
Thin Sheet Metals or Thick Plates
Currently, the market is estimating an increasing demand for the plates that is thick even though the significant share is still concerned with the thin sheet metals. However, like every other sector, flexibility has become a critical concern regarding both size and materials. Therefore, in the field of sheet metal laser cutting, researchers are estimating solutions that will guarantee efficiency, quality, and flexibility. In the sheet metal laser cutting, the technology of CO2 is the most popular one. Still, there are many new solutions that are coming up like solid-state laser cutting so that they can make sure better performance and higher efficiency.
