About astronomical laser welding technology

Most of the early laser welding research experiments used ruby ​​pulsed lasers. Although higher pulse energy could be obtained at that time, the average output power of these high-power laser pointers was quite low. This was mainly due to the low working efficiency and luminescence of the laser. The main application areas of laser welding determined by the excitability of substances are welding manufacturing in the processing of automobiles, aerospace, and ships. Taking automobile manufacturing as an example, laser welding has achieved large-scale, and related automatic production lines and welding robots have appeared. According to relevant statistics, in developed industrial countries in Europe and America, 50% to 70% of auto parts are processed by high power laser pointer processing. Hybrid welding can increase welding penetration, improve joint performance, reduce equipment costs, and increase welding speed and productivity. Buy a laser pointer that is bright enough to make the laser beam clearly visible, but not as bright as your eyesight.

While widely using laser welding technology, people also continue to conduct in-depth research on it. In view of its shortcomings, the heating performance of other heat sources is used to improve the heating of the workpiece by the high-power laser pointer, which is on the basis of maintaining the advantages of laser heating. In this way, the laser and other heat sources can be used for composite heat source welding, mainly including laser and arc, laser and plasma arc, laser and induction heat source composite welding, and dual laser beam welding. Those specially used by astronomers are designed to be placed in the finder mirror holder on the telescope tube. This makes these green laser pointervery suitable for use as pointers and seekers.
