Manufacturing Industry
Laser welding technology is widely used in automobile manufacturing abroad. Statistics show that in 2000, there were over 100 laser welding production lines for cutting blanks worldwide, producing 70 million welded blanks for automobile components annually, and this number continues to grow at a high rate.
Powder Metallurgy
With the continuous development of science and technology, many industrial technologies have special requirements for materials, and materials manufactured using casting methods can no longer meet these needs.
Automotive Industry
In the late 1980s, kilowatt-level lasers were successfully applied to industrial production. Today, laser welding production lines have appeared on a large scale in the automotive manufacturing industry, becoming one of its most prominent achievements.
Electronics Industry
Laser welding has been widely used in the electronics industry, especially in the microelectronics industry. Due to its small heat-affected zone, concentrated and rapid heating, and low thermal stress, laser welding is showing unique advantages in the packaging of integrated circuits and semiconductor device housings. Laser welding has also been applied in the development of vacuum devices, such as molybdenum focusing electrodes and stainless steel support rings, and fast-heating cathode filament assemblies.
Biomedicine
Laser welding of biological tissues began in the 1970s. The successful welding of fallopian tubes and blood vessels with lasers and the superior performance demonstrated by the technology prompted more researchers to attempt to weld various biological tissues and extend the technology to welding other tissues.
