Laser welding process and the necessary facilities

Laser (the radiation produced in the stimulated radiation of light amplification) is a special nature of light, color and consistency, so you can focus the light to do a small spot of steel on melting. To create the laser radiation, we need the laser medium. In the energy transfer from the outside to the media at the same time, can be stimulated to produce molecules. This resonator beam in monochromatic light will be reflected between two mirrors, the reflection pool time and space to produce the photon, one can partially transparent mirror that reflects this ray units resonator.

Important for high-power laser applications, there are two: carbon dioxide laser and Nd: YAG laser. Carbon dioxide laser is a gas laser, is the laser radiation to produce the medium is a gas used to stimulate the process is the discharge process, carbon dioxide laser wavelength is 10.6mm. Nd: YAG laser is a solid laser medium is neodymium laser radiation in the atomic lattice in the alumina. As the laser radiation is relatively high density of atoms, so the size of solid-state laser is smaller than the gas laser, Nd: YAG laser wavelength of 1064nm, is one-tenth of carbon dioxide laser.

Carbon dioxide laser is now more powerful laser, but the Nd: YAG laser control system strong competitive advantage. As carbon dioxide laser wavelength 10.6mm, it is necessary to install a "steep" device, which limits the possible movement. The Nd: YAG laser radiation can be a flexible optical waveguide fiber to boot, so you can allow the laser head to move freely.
