Comparison of CO2 Laser Cutting Machine and Laser Brazing Laser Cutting Machine
In recent years, we have seen the rapid development of science and technology in our great motherland. This made me feel extremely proud for me as a Chinese. With the advancement of technology and the progress of people, we will join the Chinese cutting machine trading network to make progress together. Join the hotline, we look forward to your call.

From the perspective of modern laser cutting and welding machine application fields and the technical requirements put forward by users, the future direction of laser cutting and welding is undoubtedly high power, large-format, high-efficiency, one-time molding, and high intelligence.
HCL Lasers has been dedicated to high-power laser and plasma technology applications. Here mainly elaborated is the difference between CO2 laser cutting machine and fiber laser cutting machine processing:
First of all, as the mainstream of the traditional laser cutting and welding equipment, CO2 lasers are used, which can stably cut carbon steel within 20mm, stainless steel within 10mm, and aluminum alloy below 8mm. Fiber lasers have obvious advantages when cutting thin plates up to 4 mm, and they are inferior in cutting thick plates due to the influence of the solid laser wavelength. Laser cutting machine is not universal, CO2 laser wavelength is 10.6um, solid laser such as YAG or fiber laser wavelength of 1.06um, the former is more easily absorbed by non-metallic, can be high-quality cutting wood, acrylic, PP, organic glass Other non-metallic materials, the latter are not easily absorbed by non-metal, it can not cut non-metallic materials, but the two lasers in the encounter copper, silver, pure aluminum and other high reflective materials can do nothing.
Second, because the wavelengths of both CO2 and fiber lasers differ by an order of magnitude, the former cannot be transmitted by optical fibers, and the latter can be transmitted by optical fibers, which greatly increases the flexibility of processing. Before the fiber laser was introduced to the market, in order to achieve three-dimensional processing, we used optical joint technology to guide the CO2 laser to a three-dimensional curved surface through a highly-accurate and dynamic combinational mirror system to realize the three-dimensional processing of CO2 lasers. The limitations of precision processing technology are mainly in the hands of a handful of developed countries in Europe and the United States. They are expensive, require high maintenance, and gradually lose their market while the fiber laser's market share is gradually expanding. Because fiber lasers can transmit through optical fibers, the degree of flexibility is unprecedentedly improved, especially for the automotive industry, because they are basically about 1 mm thin-surface curved surface processing, and fiber lasers are matched with the same flexible robot system, which has low costs and fewer failure points. The maintenance is convenient and the speed is surprisingly fast. This market is firmly occupied by others.
Thirdly, the photoelectric conversion rate of fiber lasers is as high as 25% or more, and the photoelectric conversion rate of CO2 lasers is only about 10%. The advantages of fiber lasers in terms of electricity consumption, supporting cooling systems, etc. are quite obvious, if the manufacturers of fiber lasers are more The price is a little more appropriate, and the plate cutting process is solved. The threat to the CO2 laser will be enormous. However, as a new type of laser technology, fiber laser is far less popular than CO2 laser. The stability, reliability, and convenience of after-sales service have yet to be observed by the market.
It is worth mentioning that, according to international safety standards, laser hazard rating is divided into 4 levels, CO2 laser is a class of least harm, and fiber laser is short of wavelength because it is harmful to the human body because of the eyes, which belongs to the class that has the greatest harm. For safety reasons, fiber laser processing requires a fully enclosed environment.
