- What to pay attention to when working with hand-held laserwelding: the welding seam is yellow, and the air pressure may not be adjusted properly What can be assured is that although the uniform motion seems to be very demanding, in actual operation, it is easy to find the ideal welding speed after repeated trials. Compared with traditional welding workmanship, handheld laser welding is quick to start and easy to adapt. This is also one of its biggest advantages. Protective gas There are two main functions of the shielding gas: 1. Exclude the air in the local area of the welding and avoid the appearance of oxide film on the surface of the material; 2. Suppress the plasma cloud generated during high-power laser welding. Stainless steel wireless weldingIndustry News August 28, 2021
- Fiber laser will become the pillar of global laser growthA new round of reports by overseas market research institutions shows that the demand for fiber laser equipment in North America, Europe and Asia is still growing. It is expected that the global market in this field will maintain an average annual compound growth rate of 7-8% in the future. Reached 2.4 billion U.S. dollars.Industry News August 28, 2021
- What is the application prospect of high-power laser cleaning?The application range of laser cleaning is very wide. As a major manufacturing country, laser cleaning/rust removal has great development potential in industrial applications. The occurrence of the Sino-US trade war has made domestic fiber laser manufacturers more important, and more and more domestic fiber laser manufacturers have realized that only by insisting on innovative and leading products can they enhance their core competitiveness. Only by mastering the core technology in our own hands can the opportunities of the Sino-US trade war outweigh the challenges. Since its establishment, Raycus Laser has been firmly committed to the development direction of a powerful country in science and technology, and has embarked on the vertical integration of the entire industry chain. Core components from chips to optical fibers have mastered key technologies through independent research and development and industrial mergers and acquisitions. A large-scale production.

- The key factors to improve the quality of laser cutting and weldingCurrently, lasers are divided into two categories: continuous and pulsed. Dr. Gao said: “When using continuous laser or long-pulse laser for processing, the material often needs to go through the process of solid-state heating, melting, liquid heating and vaporization. If a short-pulse laser is used, these three changes will be skipped directly. Reach the last step to realize vaporized cutting."
- Why laser cleaning will become the general trend?Figure 3. Absorption of light of different wavelengths by 921A steel and epoxy zinc-rich paint 3. The appropriate laser incident angle makes the cleaning effect twice the result with half the effort When the laser is incident at a certain oblique angle, the laser is directly radiated under the adhered particles, resulting in higher thermoelastic stress. Compared with normal incident, the contaminants are easier to be removed. In addition, the study found that as the tilt angle increases, the laser radiation area becomes wider (see Figure 4). When the tilt angle is 20 degrees, the area to be cleaned is about 10 times that of normal incidence, which effectively increases the laser The efficiency of cleaning.Industry News August 27, 2021

- Welding effect of handheld laser welding machine5. Use optical instruments to observe the laser beam, such as binoculars, microscopes, telescopes, etc., to observe the laser beam, the possibility of laser damage to the eyes increases greatly. When using such optical instruments, strict safety calculations must be carried out, and optical filters and appropriate interlocking protective equipment must be added to ensure that the amount of reflection on the human eye is lower than the safety standard value of the laser.Industry News August 26, 2021
