Characteristics and Application Advantages of High Power Fiber
In the industrial processing, laser processing technology is the use of laser and material
interaction characteristics of the material cutting, welding, surface treatment, drilling and
micro-processing, such as a processing technology, it is high power fiber laser market prospects
Broad application areas.
1. Advantages of high power fiber lasers
At present commercialized fiber laser output power continuous power has risen to the order of
several kilowatts, as well as the level of watts. Compared with the general laser, fiber laser
has many unique advantages, such as good beam quality; small size, light weight, maintenance-free;
air cooling, easy to operate; low operating costs, can be used in industrial environments; High
precision, fast speed; high energy conversion efficiency, can achieve intelligent, automated,
flexible operation. Based on the above advantages, its application has been extended to the
automotive manufacturing, shipbuilding and aviation manufacturing and other metal and
non-metallic materials, laser cutting, laser welding and so on.
2. Industrial applications of high power fiber lasers
In industrial processing, laser processing technology is the use of laser and material
interaction characteristics of the material cutting, welding, surface treatment, drilling and
micro-processing, such as a processing technology, it is high power fiber laser market, the
broadest prospects Application areas. Compared with the mechanical processing, laser processing
with a wide range of processing, non-contact processing, small pollution, speed, can be
automatically controlled, etc., known as "the future manufacturing system of common processing
means.
Compared with the traditional high power laser, the ytterbium-doped high-power fiber laser with
operating wavelength in the range of 1060 ~ 1200 nm has the advantages of high conversion
efficiency, good beam quality, long maintenance period and low running cost. Its extremely high
efficiency and Power in the material processing can be comparable with the traditional YAG laser.
In the field of laser marking, as fiber lasers have high beam quality and positioning accuracy,
IC manufacturers have begun to replace inefficient cq lasers and flash-pumped
Nd: YAG pulsed laser marking systems with fiber laser marking systems, In the field of welding,
laser welding and sintering of the required power of 50-500 W, metal welding and brazing for the
5-20 in the field of welding, welding and welding on the semiconductor chip and packaging small
nameplate, it is also commonly used in plastic and metal marking; KW, high-power fiber
lasers fully able to meet the requirements.
3. Typical examples of high power fiber laser applications
Recently, the international use of fiber laser welding technology in the shipbuilding,
automotive manufacturing applications have been considerable attention. In developed countries
in Europe and America, about 50% -70% of the auto parts are used in laser processing technology,
and laser welding and laser cutting mainly. Shanghai Volkswagen and other automobile
manufacturers also use laser processing technology welding body and cabinet and other components.
Europe and the United States and Japan's major large-scale shipyard has a large number of laser
processing technology, such as the United States in the latest construction of new ships widely
used high-strength, low-alloy steel T-type components, the use of laser welding technology, the
ship's weight greatly reduced. Hull plate in order to adapt to the needs of ocean mobility, are
designed to have a complex three-dimensional curvature shape, laser-assisted plate molding
technology can replace laborious, time-consuming, with a certain risk of mechanical
heating molding process, application prospects. Japan's Kawasaki Heavy Industries and other
shipbuilding companies have installed a high-power laser flat panel cutting system. Germany's
Meyer Werft also installed four 12KW CO2 lasers for welding hammers with different lengths.
At present, the United States, Europe and other regions are ongoing high-power fiber laser
industrial processing equipment development, ongoing 2KW, 6KW output of industrial-grade fiber
laser processing equipment secondary development. China has developed a small power series of
industrial fiber laser products. Small and medium-power laser processing equipment, such as
laser marking machine, engraving machine, cutting machine, welding machine, also widely used in
various industries, but high-power fiber laser industrial processing applications are still
blank, and in China's shipbuilding industry has not even used laser Processing Technology.
