The customer is very satisfied with the color of cell phone jammer

The late 1980s, kilowatt-class laser successfully applied to industrial production, now has a large-scale production line of laser welding in the automotive industry, automotive manufacturing outstanding achievements. Germany, Audi, Mercedes-Benz, Volkswagen, Volvo of Sweden and other European car manufacturers as early as the 1980s were the first to use laser welding roof, body, side boxes, and sheet metal welding, 90 years of U.S. General Motors, Ford and Chrysler Chrysler's race to the introduction of laser welding automobile manufacturing, despite the late start, but growing fast. Italy's Fiat, in most steel components used in laser welding assembly, welding, Japan's Nissan, Honda and Toyota Motor Corporation in the manufacture of body panels are used in laser welding and cutting processes, laser welding of high strength steel assembly because of its excellent performance in automotive body manufacturing increasingly used, according to American Metal Market Statistics, the end of 2002, the laser welding of steel consumption will reach 70000t 3 times more than in 1998. According to the automotive industry volume, characterized by a high degree of automation, laser welding equipment to high-power, multi-style direction. The customer is very satisfied with the color of cell phone jammer .
In the process, the U.S. Sandia National Laboratories conducted jointly with PrattWitney added during the laser welding of metal powder and wire research, Bremen, Germany, Institute of Applied Beam Technology in the use of laser welding of aluminum alloy body frame in a lot of research, Add in the weld that is filled with more than help to eliminate hot cracking, increased welding speed, solve the problem of tolerance, the development of the production line at Mercedes-Benz plant have been put into production. Laser welding in the electronics industry, especially in the microelectronics industry has been widely used. As the weld heat affected zone of laser focus on rapid heating, thermal stress is low, which are integrated circuits and semiconductor devices encapsulated in the shell, showing the unique advantages of the research and development in a vacuum device, laser welding has been applied, such as molybdenum focus electrode and the stainless steel support ring, fast hot cathode filament components. Sensor or thermostat in the elastic thin-walled corrugated sheet thickness in 0.05-0.1mm, using traditional welding methods are difficult to resolve, TIG welding easy to wear welding, plasma stability is poor, many factors and the use of laser welding works well, has been widely the application. The  cell phone jammer with compass will be better in the quality.
