Laser processing is one of the promising areas in laser applications. More than 20 laser processing technologies have been developed.
Laser cutting pipe processing is an important technology in laser processing. The quality of laser welding is directly related to the intelligence and accuracy of the welding system. A welding processing system must be able to produce welding products.
The laser welding system is generally composed of laser, optical system, laser processing machine tool, process parameter detection system, shielding gas transmission system, control detection system and so on. The core of the laser welding system is the laser.
Laser welding has the advantages of high precision, high efficiency, high strength, and good timeliness, ensuring quality, output and delivery time. At present, laser welding has become a competitive processing method in the processing industry. It is widely used in machinery, electronics, battery, aviation, instrument and other industries for spot welding, overlap welding and sealing welding of workpieces with special requirements.
brass machining requires that the laser has a high rated output power, a wide power adjustment range, a slow rise and slow fall of power, to ensure the quality of the beginning and end of the weld, and the work is stable and reliable. The lateral mode is a low-order mode or a fundamental mode. There are CO2 lasers, YAG lasers, LD pumped solid-state lasers, fiber lasers and semiconductor lasers. High-power semiconductor lasers are becoming more and more mature, and the commercial laser power has reached several kilowatts. The high-power semiconductor laser has uniform beam energy distribution, and the spot shape can be adjusted according to needs. The photoelectric conversion efficiency is high, the structure is compact, the weight is light, and the volume is small, which is convenient for field application. The disadvantage is that the beam quality is average and the divergence is high.
my country's cnc milling china technology is at the world's advanced level. It has the technology and ability of laser forming complex titanium alloy parts of more than 12 square meters, and has invested in the prototype and product manufacturing of many domestic aviation scientific research projects.
In October 2013, Chinese welding experts won the Brooke Prize, a high academic award in the field of welding, and the level of laser welding in China has been recognized by the world. At present, laser welding machine technology has been widely used in high-precision manufacturing fields such as automobiles, ships, airplanes, and high-speed railways, greatly improving people's quality of life, and leading the home appliance industry into the manufacturing era. Through home appliance technology, people will cherish and value science and technology more. Advanced laser technology can bring huge changes to people's lives.
