Combining with the market growth rate of my country's laser cutting equipment in recent years and the demand prospects of my country's laser cutting equipment, according to Han's Laser forecasts, the market size of my country's laser cutting equipment is still growing steadily. It is estimated that by 2020, my country's laser cutting equipment market will reach 1.9 billion yuan.

Fiber laser is the core equipment of fiber laser cutting machine, and it will have a great impact on the use of the whole machine after failure. One of the main reasons for the failure of the fiber laser power supply is the condensation inside the laser. The condensation inside the city fiber laser is closely related to the daily bad habits of customers operating and using the fiber laser.

The laser adopts the QCW working mode, which has the characteristics of high peak power, large pulse energy, excellent beam quality and ultra-high power stability. It is widely used in precision welding (3C industry, power battery industry, medical industry), precision cutting (brittle materials) And fine sheet metal cutting, ceramic scribing), precision punching, additive manufacturing and other fields; the output mode can be switched between continuous and quasi-continuous according to customer needs, so it has more processing advantages.

The price war for laser-related products will continue, mainly lasers and laser processing equipment, while the price competition between core components and supporting products will not be so obvious. The industry has seen sales growth, but the unit price of a single machine has dropped, and corporate profits have been compressed. For most laser equipment companies, the future way is to combine laser, numerical control and processing technology development to further develop and master more core technologies. If conditions permit, they should cooperate with automation companies and terminal application companies to jointly develop processes and customize them according to their needs. Equipment and production line.

Guidance of perforation method: 1. The peak power is as high as possible to improve the efficiency of perforation; 2. Ensure that the laser spot will not hit the nozzle, and the perforation focus will be appropriately reduced; 3. The oxygen perforation air pressure is equivalent to the cutting air pressure; 4. Add stop light blowing between multi-level perforation, which is not easy to blast.

■Micro-processing is expected to achieve the highest compound annual growth rate (17.5%) in the sub-industry According to application breakdown, ultrafast lasers are divided into micro-processing, bioimaging, scientific research, medical device manufacturing, and cardiovascular stent manufacturing. The bioimaging field has the highest market share in 2020, and it is expected to grow at a high compound annual growth rate from 2021 to 2030. Divided by end users, the market can be divided into consumer electronics, medical, automotive, aerospace and defense, industrial and others. The medical field’s market share will be the highest in 2020, and the consumer electronics field is expected to grow at a high compound annual growth rate from 2021 to 2030.

Dual-beam welding of aluminum alloy is also a way to eliminate air holes. A 6 kW continuous fiber laser was used to perform dual-beam butt welding of 5052 aluminum alloy. The two-beam parallel and serial welding modes and welding at different welding speeds were studied. The study of seam morphology and structure found that there are large holes in the welds welded in parallel with dual beams, and welding aluminum alloys in series can obtain good weld formation without porosity.

The photoelectric conversion rate of this series of 2μm wavelength Thulium-doped continuous fiber lasers developed by Feibo Laser can reach more than 20%, which is more energy-efficient than CO2 lasers. Coupled with the characteristics of simple structure, good beam quality, easy integration, easy operation and maintenance-free of thulium-doped fiber laser, it is expected that it will show its talents in the wood cutting field in the future and gradually replace CO2 lasers.

Nanosecond micro-welding technology is only one of many fiber laser manufacturing processes. Fiber laser manufacturing processes are increasingly used to overcome the challenges faced by today's industrial manufacturing industry and are the key to helping realize the current technological revolution.
