Due to the unique advantages of laser welding head welding technology, in automobile manufacturing and production, the frame, body, carriage, engine, automobile gear, roof, etc. are inseparable from welding head technology. Laser welding head welding has small deformation and weld quality. High, no solder and other characteristics, become the standard process of automotive parts manufacturing.

Characteristics and application fields of laser welding head
Laser head technology uses a polarizer to reflect the beam produced by the laser in order to focus it in a focusing device to produce a high-energy beam. If the focus is close to the workpiece, the workpiece will melt and evaporate within milliseconds. This effect can be used to generate high-power CO2 and high-power YAG lasers during the welding process, opening up a new field of laser welding head welding. The key to laser welding head equipment is a high-power laser. There are mainly two types, one is solid state laser, also known as Nd:YAG laser. Nd (Neodymium) is a rare earth element and YAG stands for Yttrium Aluminum Garnet, which has a crystal structure similar to ruby. The wavelength of the Nd:YAG laser is 1.06 μm.

With the rapid development of laser head manufacturing technology and the late start of laser head technology in China, there is still a large gap between advanced laser head technology at home and abroad. However, science and technology do not recognize national borders. In recent years, domestic laser head technology has developed rapidly, and is gradually narrowing the industrial gap and combining with international standards. In 2018, an in-depth study of laser cutting heads in the global and Chinese markets shows that despite the rapid development of the laser head industry, high-end laser head products are still occupied by multinational companies in the United States, Japan and Germany. Like other regions, domestic companies are mainly concentrated in the low-end product market. Taking the small and medium power cutting head market as an example, China's medium and small power laser cutting head equipment industry has matured, but the high power laser head equipment is still in

Main working parameters of equipment for laser cutting and laser welding
Laser cutting heads are basically similar to welding heads, except that the welding heads require the use of a laser welding head, and each requires the use of a laser cutting torch (also known as a cutting gun). Laser cutting mostly adopts CO2 laser cutting equipment, which is mainly composed of laser, light guide system, numerical control motion system, cutting torch, smoking system, etc. The main working parameters of laser cutting equipment are:
