Vane of 10,000-watt laser technology route—multiplexing or single-channel amplification?
In 2021, China will be the only major economy in the world to recover rapidly from the 2020 epidemic. The added value of industries above designated size in the whole year will increase by 9.6% over the previous year, of which the added value of high-tech manufacturing and equipment manufacturing will increase respectively. 18.2%, 12.9%. In particular, China’s laser industry has developed rapidly in recent years, and the scale of the laser industry chain has increased rapidly. In 2020, the total sales revenue of laser equipment (including imports) in the fields of industry, information, commerce, medicine and scientific research will be 69.2 billion yuan, a year-on-year increase over 2019. up 5.2 percentage points. With the continued prosperity of photovoltaic, power battery, automobile and other industries, the overall sales revenue of China’s laser equipment market will increase by 15.6% year-on-year in 2021, reaching 80 billionyuan.
A brief analysis of the heat dissipation technology of mainstream handheld laser welding machines
With the increasing application of fiber lasers, the reliability of fiber lasers has attracted more and more attention, including the reliability of laser output performance, the reliability of electronic components, the reliability of optical devices, the reliability of systems, etc. Wait. Most of these are closely related to the thermal properties of the laser itself. In addition, the temperature has a great influence on the performance of the laser, especially the output power and output stability of the laser.
The industrial code – GW laser in metal 3D printing
Additive manufacturing (3D printing) of metal materials is in great demand in aviation, aerospace, navigation, vehicles, mold manufacturing, medical equipment and other fields. At present, the heat source used in the metal additive manufacturing process includes three high-energy beams of laser beam, electron beam, micro beam plasma and sintering heat input, etc., of which the laser beam is the most widely used high-energy beam heat source in the field of metal additive manufacturing. Compared with the electron beam and microbeam plasma heat source, the laser beam has the advantages of fine spot, low cost, and directional action to the specified material position, which can realize the instantaneous melting of metal materials and meet the requirements of fusion channel lapping and part forming.
