The quality assurance of laser pointer has been performed in this laser pointer company

 The quality assurance of laser pointer has been performed in this laser pointer company.
Japan is the world's first successful development of the YAG laser welding is used in a nuclear reactor steam generator tube repair fine, in the domestic Su Baorong and other gear also carried out laser welding technology. With the continuous development of science and technology, and many industry specific technical requirements for materials, application of smelting method of manufacturing the material can not meet the need. As the powder metallurgy materials with special properties and manufacturing advantages, in some areas such as automotive, aircraft, tools and cutting tools manufacturing materials are replacing traditional smelting, with the increasing development of powder metallurgy materials, it is connected with other parts of the problem become increasingly prominent, so that the application of powder metallurgy materials is limited. In the early 1980s, with its unique advantages of laser welding to enter the field of powder metallurgy materials processing for the application of powder metallurgy materials opens up new prospects, such as the use of powder metallurgy materials commonly used connection method of welding brazing diamond, due to a combination low intensity, especially the heat-affected zone width and intensity can not meet the requirements of high temperature caused by solder melting off, the use of laser welding can increase the weld strength and high temperature performance. 
As the laser welding as a high-quality, high precision, low distortion, high efficiency and high speed welding method, with the high-power high-power CO2 and YAG laser and fiber optic transmission technology improved, the metal molybdenum welding spotlight lens, etc. developed, so that in machinery manufacturing, aerospace, automobile, metallurgy, microelectronics and other fields of biomedical applications more widely. The current study focused on the C02 laser and YAG laser welding of metal materials theory, including laser-induced plasma spectroscopy, absorption, scattering, and intelligent control of laser welding, hybrid welding, laser welding phenomena and behavior of the hole , and the mechanism of weld defects prevention methods, etc., and nickel-base alloy, aluminum and magnesium alloy welding, welding phenomena modeling and simulation, steel materials, copper, aluminum and the connection of dissimilar materials, laser joint performance evaluation and so do some research. The innovative design of laser pointer greatly enhances the producing process of laser pointer .
Laser welding principle: Laser welding is a high-intensity laser beam radiation to the metal surface by laser interaction with metal, the metal can absorb the laser light into heat after cooling crystallization of molten metal welding.
