BMW and Volkswagen as an example can be seen in the mid-1990s, the BMW company uses the laser welding robot completed cars BMW5 series of welds, weld total length of 12m. By July 2003, the total length of the laser welding the weld has reached 1.5 million meters. Volkswagen Touran cars in Germany is a good example of the new laser welding technology program. In this new car, the number of the laser spot by 1400, and weld the total length of 70m. At the same time, Audi is also using laser welding technology to weld the body. In the production of comfortable, beautiful open-top car, the VW company's technical staff and the welding specialist Fronius companies in Austria developed a hybrid laser welding technology. The laser problem of green laser pointer  has to be recorded.
Laser marking because of the marked non-erasable, acid corrosion, will not be organic solvent, it is widely used in military quality of the product tracking. Only the shell design in the manufacture of aerospace equipment you need to repeatedly test, the shell is made of special metal materials, high strength, high hardness, high temperature, the ordinary means of cutting is difficult to complete the processing of materials, laser cutting as an efficient means of processing and widely used. Spacecraft flying in the atmosphere will produce great heat, the spacecraft need to have a lot of coating to achieve insulation, in order to smooth the process of temperature rise coating layer between the air discharge, the need in the coating The above uniform distribution of the many tiny holes. The quality of green laser pointer is dependent on the laser chip.
Also reduce the body weight, can also achieve the purpose of fuel; welding accuracy has been improved greatly. These are to help reduce the cost of production of the car, ultimately benefit consumers, the so-called "human technology". At present, in a foreign country, Germany Volkswagen brand in AudiA6, GolfA4, Passat and other roof laser welding, laser welding, BMW, General Motors Corporation in the frame at the top of General Motors, Toyota, Ford, BMW, Fiat, Mercedes, Volkswagen companies are using tailor welded blank technology, the Big Three U.S. automakers, the German Mercedes-Benz is using laser welding transmission components, Volkswagen, General Motors, Mercedes-Benz, Nissan has applied the laser cutting technology. The laser technology problem tackling of  green laser pointer is an important step.
