Common sources emitting laser source (such as lights, flames, sun, etc. luminescence) is due to the material when subjected to external energy (such as solar energy, electricity, heat, etc.) the role of electrons in atoms will absorb external energy from low energy level transition to the high energy level, that atoms are excited. The excitation process is a "stimulated absorption" process. High energy level of electrons in a very short lifetime (typically 8 to 10 seconds), in the absence of external spontaneously under the action of the transition to a low energy level laser welding machine Qingdao, will produce light (electromagnetic) radiation transition. This radiation is called spontaneous emission. Atomic spontaneous emission process is a completely random process, light-emitting atoms each process independent, unrelated, that the radiation emitted in the direction of the light is random shooting in all directions, while not the phase, the polarization state is also different are not the same. Since the excitation energy level has a width, the frequency of the emitted light is not a single, but a range. Under normal conditions of thermal equilibrium, at a high energy level on the atomic number density, and low energy level than in the low atomic number density, because the size of an atom in the energy level when the number density increases with the energy level E decreases exponentially laser welding machine price, which is famous for the Boltzmann distribution. Seen at 20 ℃, almost all of the hydrogen atoms in the ground state, make atom light emission, energy must be provided outside excited states of atoms arrive, so the ordinary light emission is broad contains two processes stimulated absorption and spontaneous radiation. In general, the radiation energy of this light source is not strong, with emission in all directions, so that more energy dispersive laser welding using a high energy laser pulses to locally heat the material within the minimal region, the laser radiation energy through heat transfer internal diffusion-oriented material, the material is melted to form a specific puddle. It is a new type of welding, mainly for thin-walled materials, precision parts welding laser welding machine, spot welding, butt welding, stitch welding, seal welding, etc., aspect ratio, weld width is small, heat-affected small area, small deformation, welding speed, weld smooth, beautiful, without treatment after welding or simply handling, high weld quality, nonporous laser welding machine supply, can be precisely controlled, focused spot size, high positioning accuracy easy to automate.
