Laser Welding Equipment Wiring Harness
Laser welding equipment wiring harness has been widely used in many industries. There are many types of laser equipment, which can be divided into medical, industrial, military, etc. according to their uses,among them, industrial laser equipment mainly includes: laser engraving machine, laser marking machine, laser welding machine, laser cutting machine, etc. Then there are three types of laser cutting machines: solid laser cutting machines, gas laser cutting machines, and fiber laser cutting machines.
Laser welding is to use high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the interior of the material through heat conduction, and the material is melted to form a specific molten pool. It is a new type of welding method, mainly for the welding of thin-walled materials and precision parts, and can realize spot welding, butt welding, stitch welding, sealing welding, etc. Small deformation, fast welding speed, smooth and beautiful welding seam, no need or simple treatment after welding, high welding seam quality, no pores, precise control, small focusing spot, high positioning accuracy, easy to realize automation.
In recent years, laser technology has been widely promoted and applied. In the field of traditional laser processing, due to the continuous improvement of processing accuracy and efficiency, traditional laser equipment is constantly being replaced and upgraded. Among them, thanks to the continuous improvement of laser power and light quality, the application field of laser technology has expanded, and more and more new downstream needs have been developed. Driven by the strong downstream demand, my country's laser equipment market has shown a trend of rapid growth. According to data, in 2017, the sales volume of China's laser equipment market reached 44.2 billion yuan, a year-on-year increase of 14.8%.
