From the modern laser cutting, welding machine applications and the technical requirements of the user point of view, laser cutting and welding is undoubtedly the future direction of development of high power, large format, high efficiency, forming a high intelligence.
Chinese laborers Fali Lai has been committed to high-power laser and plasma technology applications. Described here is mainly CO2 and fiber laser cutting machine laser cutting machine for processing differences:
First, as the mainstream of traditional laser cutting and welding equipment using CO2 laser, can be stabilized within the carbon steel cutting 20mm, 10mm stainless steel within, 8mm aluminum below. 4mm fiber laser within the cutting edge when the plate was subject to the impact of solid-state laser wavelength when it is of poor quality in the cutting plate. Laser cutting machine is not a panacea, CO2 laser wavelength 10.6um, solid-state lasers such as YAG or fiber laser wavelength of 1.06um, the former is more easily absorbed by metal, can be cut with high quality wood, acrylic, PP, plexiglass and other non-metallic materials, which are not easily absorbed non-metallic, it is not cutting non-metallic materials, but the two met the laser in copper, silver, aluminum high reflective material when they do nothing.
Second, precisely because of CO2 and fiber laser wavelength difference between an order of magnitude, the former can not be transmitted by optical fiber, optical fiber transmission which can greatly increase the degree of processing flexibility. The market early before the fiber laser, in order to achieve three-dimensional processing, we use highly sophisticated optical technology through joint with a combination of dynamic CO2 laser mirror system will lead to a three-dimensional curved surface, three-dimensional realization of CO2 laser processing, this technology because the domestic limited precision machining technology mainly lies in the hands of a few European and American developed countries, expensive, high maintenance requirements, the fiber laser, while gradually expanding its market share has gradually lost its market. The fiber laser because it can be transmitted through optical fibers, the degree of flexibility than ever before, especially for the automotive industry, because basically about 1mm sheet surface machining, fiber laser with the same flexible robot system, low cost, fault small, easy maintenance is fast and doing my part to firmly occupied this market.
Again, the fiber laser photoelectric conversion rate of more than 25%, while the CO2 laser photoelectric conversion rate of only about 10% in electricity consumption, supporting fiber laser cooling system, etc. The advantages are obvious, if more fiber laser manufacturer some, and then the right price point, and to address the plate cutting process, CO2 laser threat will be large. However, the fiber laser as a new laser technology, CO2 laser penetration is far less than its stability and reliability, the convenience of after-sales service market has yet to be a long-term observation.
It is worth mentioning that, in accordance with international safety standards, the laser damage Level 4, CO2 laser is the least harmful one, while the fiber laser due to the wave length of the human eye damage because it is large, is most dangerous level, the on safety considerations, fiber laser processing needs completely closed environment.
In addition, the fiber laser with a robotic flexible manufacturing systems in the automotive industry and related industries a long history of high status, used to be monopolized by foreign builders in recent years, the automotive industry because of the financial crisis and the continuous improvement of production technology, especially domestic high-end laser technology manufacturers such as laborers Fali Lai in support of national policies on technology research, many high-end foreign car brands and national brands Shouchang crabs and foreign share of high prices arrogant and secretive veil has been lifted, tear, laborers Fali Lai in recent years to provide the car white car body welding, laser weakening dashboard, airbag laser welding, automobile bumpers, doors, columns and other robots in flexible cutting, car bumper laser welding, automobile exhaust pipe line welding system, car automatic gear shifting sets of laser cutting equipment, etc., at the user site 24 hours a stable and efficient production, so that users at the same time praised the Chinese laborers Fali Lai to foreign builders shouted, "Wolf "!
In summary, the laser application should be directed towards high power CO2 laser application in the more stable, large format, faster machines. 2mm below the surface for processing, fiber laser is more advantageous
