Laser Machine World for Laser Technology and Laser Products

  Lasers have been hailed as one of the great inventions of the twentieth century, following nuclear power, computers, and semiconductors, and have brought about a great technological breakthrough for mankind. The laser radiation produced by lasers is famous for being the "fastest blade", the "most accurate ruler" and the "brightest light". Nowadays, laser technology plays an important role in many fields such as medicine, the military industry, communications, and so on.   The birth of the laser is the result of the tireless efforts and arduous exploration of many scientists.   In 1917, Albert Einstein proposed the concept of "stimulated radiation", which laid the cornerstone for the theoretical foundation of lasers.   Although the theory of lasers had already been proposed at that time, the actual preparation of lasers was quite challenging. By the 1950s, with the progress of photon and microwave technology, the manufacture of an oscillator cap...

With the development of industrial manufacturing in the direction of high-end, intelligent, green, new energy vehicles, lithium batteries, semiconductors, and emerging markets demand-driven, the demand for laser welding has been continuously stimulated, the scope of application and the market continues to expand. Especially in the fields of consumer electronics, new energy vehicles, and other fields, the requirements for laser welding are becoming more and more high, providing a huge market space for laser welding. However, any processing method without a good grasp of its principles and processes will produce certain defects or defective products, laser welding is no exception. Only a good understanding of these defects, and learning how to avoid producing these defects, in order to better utilize the value of laser welding, processing the appearance of fine, high-quality products. MAX  welding application engineers through the accumulation of long-term experience, summed up some ...

  The principle of laser rust removal is laser cleaning   The process of pulsed Nd: YAG laser cleaning depends on the characteristics of the light pulses generated by the laser and is based on a photophysical reaction caused by the interaction between the high-intensity light beam, the short-pulsed laser light, and the contaminated layer. The physical principle can be summarized as follows:   a) The beam emitted by the laser is absorbed by the contaminated layer on the surface to be treated. b) The absorption of the large energy creates a rapidly expanding plasma (highly ionized unstable gas), which generates a shock wave. c) The shock wave causes the contaminants to fragment and be removed. d) The width of the light pulse must be short enough to avoid the heat buildup that destroys the treated surface. e) Experiments have shown that plasma is generated on metal surfaces when oxides are present on the surface.   Plasma is only generated at energy densities above a t...

The battery module is the heart of an electric vehicle. Electric vehicles are powered by batteries, so the reliability of the battery is critical to the safety of the vehicle. Having launched its first all-electric vehicle, the i3, back in 2013, the BMW Motor Group is well aware of the multiple challenges of battery production. As production capacity continues to increase, so does the complexity of battery production - for example, as many as 144 welds are required in the production of BMW's fifth-generation battery modules.   With the Ophir BeamWatch Integrated automated laser beam measurement system, automakers can inspect the laser beam before welding each new battery module without disrupting the production cycle. Prior to Ophir BeamWatch Integrated, the automaker had to perform weekly spot checks with micrographs in order to confirm the ideal weld depth. Beam quality monitoring without compromising production cycles Laser welding in battery production requires absolute precisi...

There is a wide range of common laser systems for a variety of applications such as materials processing, laser surgery, and remote sensing, but many laser systems share common key parameters. Establishing common terminology for these parameters prevents miscommunication, and understanding them allows for proper specification of laser systems and components to meet application requirements. Basic Parameters The following basic parameters are the most fundamental concepts of a laser system and are essential to understanding the more advanced points.   1: Wavelength (typical units: nm to µm) The wavelength of a laser describes the spatial frequency of the emitted light wave. The optimal wavelength for a given use case is highly dependent on the application. Different materials will have unique wavelength-dependent absorption properties in material processing, resulting in different interactions with the material. Similarly, atmospheric absorption and interference will affect certain ...

Careful people  will find small but crucial marks on the cables. These marks will directly affect the operation of the equipment. Nowadays, more and more industries are beginning to use laser marking machines to mark their cables, making the marks clearer and more precise. precise. So, why does the laser marking machine become a "sharp tool" for cable marking? A cable is an important electrical equipment used to transmit power or signals. Cables are required for power transmission, power distribution, power transmission within buildings, communication data, transportation, industry, etc. Then the marking process on the cable is particularly important. It must be clearly visible and cannot be oxidized or smeared. However, the laser marking machine has become a powerful tool for cable marking with clear and lasting marking .   A laser marking machine is a method that uses a high-energy laser beam to irradiate the surface of the material to form a mark. Compared with traditional...
