Laser welding machine welding is an important part of laser manufacturing technology. In 1960, the United States successfully developed the world's first ruby laser; in 1962, reports on laser applications including laser welding appeared; from 1971 to 1972, with the practical application of kilowatt CO2 laser welding equipment, laser welding took place Variations, a few millimeters thick steel plates can be fully penetrated at one time, showing the great potential of high-power laser welding.
Laser welding technology was first used in car body manufacturing in the mid-1980s, shipbuilding in the mid-1990s, and A380 large aircraft fuselage manufacturing in the early 2000s. Airbus applied laser welding technology instead of riveting, and successfully achieved the goal of reducing the weight of the aircraft by 20%, making a seminal contribution to the application of laser technology in the aviation industry. Laser welding can realize the connection of many types of materials, and has many advantages that other fusion welding processes cannot compare with. Among them, the most prominent is that laser welding can connect thin-plate alloy materials (such as aluminum alloy, titanium) Alloy, etc.), and has the advantages of small deformation of components, high joint quality and good reproducibility. This shows that the future aviation industry will be an important field for the application of laser welding technology.
