After the optical fiber transmission by the laser light speed of good quality
Optical fiber transmission laser welding machine is the use of energy fiber, the solid-state laser generated 1064nm laser, through the 3000mw laser pointer coupling technology to the fiber, and then the fiber in the laser through the output mirror to the workpiece surface, to achieve the purpose of welding; Laser, you can use the flexibility of the fiber, so that the laser can be any angle on the workpiece processing, to achieve a multi-dimensional flexible processing; fiber on the laser energy and homogenization of the laser spot energy can be modeled output, and laser Homogenization, so that the laser beam quality is better to improve the quality of welding.
Operation requirements and maintenance: CO2 laser need to adjust the optical path, and the effect of optical path adjustment will affect the cutting quality, so the operator must have a certain skill requirements, and the need for external optical path maintenance; YAG solid laser thermal lens effect is obvious, ; Fiber laser fiber transmission, no adjustment, maintenance-free, high stability, easier operation. Cutting speed and effect: Fiber laser cutting speed is 2-3 times the same power CO2 laser, especially in the metal sheet cutting, fiber laser cutting machine cutting speed in the three types of laser cutting machine has obvious advantages. Fiber laser cutting machine beam quality is good, cutting gap is small, cutting edge formation.
The reason, on the one hand, several kilowatt-class continuous high power laser pointer technology is mature, the emergence of a strong fiber laser manufacturers, the formation of a competitive mass production scale, to ensure adequate supply of the market; the other hand, fiber laser The advantages of material processing to make it favored in the market, more efficient solution to traditional enterprises with high production costs, low production efficiency pain points, so there is a huge market space.
After the optical fiber transmission by the laser light speed of good quality, spot fine, uniform energy distribution; initial section of power stability, change small, improve product qualification rate. It is believed that with the laser equipment line to the energy negative feedback fiber laser welding machine research and development efforts to increase the energy negative feedback fiber laser welding machine development will be getting better and better. In layman's terms, energy feedback can well control the average distribution of the speed of light and reduce the unevenness of welding.
Fiber laser cutting more sophisticated, focusing focus up to 25um, small heat affected area, small slits, small workpiece deformation. As a flexible processing method, fiber lasers can be combined with automatic control system to achieve automatic tracking, automatic search edge, automatic nesting material, greatly enhance the production efficiency, its metal sheet cutting widely used, the performance is better, can better meet the fine Cutting processing requirements. Fiber 2000mw laser pointer have replaced a considerable portion of CO2 laser and YAG solid-state lasers in the field of sheet metal cutting applications, and future breakthroughs in high-power fiber lasers will likely accelerate this alternative.
