Laser welding applications

Perfect Laser Laser Welding Machine

In the late 1980s, 1000w and above laser was successfully applied to industrial production. Now laser welding production lines have entered the automotive industry on a large scale to become one of the most outstanding achievements of the automotive industry. in the 1980, the European Vehicle manufacturers, such as Audi, Mercedes-Benz, Volkswagen, and Sweden's Volvo, have pioneered the use of laser to weld sheet metal, such as roof, body, and side frame of cars. In the 1990s, U.S. General Motors, Ford, and Chrysler Corporation introduced laser welding into automobile manufacturing. although starting late, it has developed rapidly. Fiat Italy uses laser welding in the welding assembly of most steel components. Japan's Nissan, Honda, and Toyota Motor Corporation all use laser welding and cutting processes in the manufacturing of body panels. Because high-strength steel laser welding assemblies have excellent performance, it was used In the manufacture of automobile body more and more. according to the US metal market statistics, by the end of 2002, the consumption of laser-welded steel structures will reach 70,000 tons, which added 3 times more than in 1998. According to the characteristics of large volume and high automation in the automotive industry, laser welding equipment is developing in the direction of high power and multiple paths. In the process, United States Sandia National Laboratories and Pratt Witney jointly carried out research on the addition of powder metal and wire during the laser welding process, and the German Institute of Applied Light Beam Technology in Bremen, Germany conducted a lot of research on the use of laser-welded aluminum alloy body frames. It is believed that the addition of filler in the welding can help eliminate hot cracks, increases welding speeds, and solves tolerance problems. The production line has been put into production at the Mercedes-Benz factory.

Laser welding has been widely used in the electronics industry, especially in the microelectronics industry. Because laser welding has a small heat affected zone, rapid heating concentration, and low thermal stress, it is showing unique advantages in the packaging of integrated circuit and semiconductor device housings. In the development of vacuum devices,such as Molybdenum focusing pole and stainless steel support ring, fast hot cathode filament assembly, laser welding has also been applied. The thickness of elastic thin-wall corrugated sheet in sensors or thermostats is 0.05-0.1mm, which is difficult to solve by traditional welding methods. TIG welding is easy to weld through out, and the plasma stability is poor. There are many influencing factors. But it is perfect to adopt laser welding. Therefore it is used widely.

In recent years, laser welding has gradually been applied to the assembly of printed circuit boards. As the degree of integration of the circuit becomes higher, the size of the parts becomes smaller, and the pitch of the pins becomes smaller, conventional tools have been difficult to operate in a small space. The laser can achieve welding because it does not need to touch the parts. It solves this problem very well, which it attracts the attention of circuit board manufacturers.

Due to the high precision of laser processing, it is suitable for the precious and delicate products in the jewelry industry. Because the laser focused beam is very fine, the tiny parts of the jewelry can be enlarged by the microscope to achieve precise welding. the laser spot welder is a necessary equipment for the connection of the jewelry chain and the setting of the jewels.
