Research on the application of laser processing technology in agricultural machinery manufacturing
Application of laser cutting technology in agricultural machinery manufacturing Laser cutting technology applies a laser beam to the surface that needs to be processed for processing. At this time, a very high temperature will be formed on the surface to complete the processing. After the application of the laser beam, the oxidation reaction can be achieved. The steam and slag generated at this time can be directly discharged into the external space through the auxiliary gas, and then various shapes and sizes that meet the user’s requirements can be formed on the surface of the workpiece. In this way The entire processing process can be completed. In addition, laser cutting […]

Application of laser processing technology in the manufacturing of transmission tower
Principles, characteristics and advantages of laser processing technology 1. 1 Principle of laser processing technology Laser processing is a very important high-energy beam processing method, which has the characteristics of strong laser directionality, high brightness, good monochromaticity, and good coherence. The principle of laser processing technology is that the laser light emitted by the laser generator is converted and focused by the lens to obtain a highly parallel columnar or strip-shaped beam. The extremely high energy density is obtained and concentrated into a small area on the processing material. After absorbing the energy of laser irradiation, the material heats up rapidly in a very short time and undergoes a series […]
Research status and application of laser processing technology in marine engineering
Application of laser cutting technology in marine engineering There is a huge demand for metal cutting in the field of marine engineering.

Laser Cutting Smoke Hazards and Smoke Exhaust Mechanism Laser Cutting Smoke Hazards The smoke released when laser cutting metal plates can be roughly divided into dust and aerosols. 97% of them have a diameter of less than 5.7 μm, which means that most of the smoke can be Inhaled into the body. Depending on the cutting material and scene, other harmful substances will be produced, such as oil on the surface of the board, and very complex hydrocarbon composite gases; for example, if the surface of the board is filmed, aliphatic and olefin compounds will be released during cutting, accompanied by Distinctive odor. If the smoke and dust generated by […]
Basic principles and influencing factors of laser cutting
Laser cutting principle Laser is the product of stimulated radiation. Its production is inseparable from three key elements: working material, pump and resonant cavity. After absorbing energy, low-energy level particles will transition to high-energy level orbits, but the state of high-energy level particles is unstable and will Falling to a low-energy orbit and emitting photons at any time, laser light is generated when many particles emit photons with high consistency at the same time. Laser processing can be divided into hot processing and cold processing according to the size of photon energy. Cold processing is generally used in the laser marking process of plastic parts. The laser completes the separation […]
