Release Time : 2024-12-31
As a high-precision and high-efficiency welding method, laser welding is widely used in various industrial fields. As one of the core components of the laser welding machine, laser lens zinc selenide plays a key role in focusing the laser beam accurately to the welding point. How zinc selenide lenses can withstand high temperature without deformation has become the focus of attention during high-temperature laser welding.
Zinc selenide lenses have excellent thermal and chemical stability, which is the key to their ability to withstand high temperatures. During laser welding, the lenses need to be exposed to high temperatures for a long time, and zinc selenide has a high melting point and can resist high temperature erosion to a certain extent. At the same time, the thermal expansion coefficient of zinc selenide lenses is small, which means that at high temperatures, the size of the lenses changes relatively little, thereby ensuring the stability and accuracy of the focus point.
In addition to the characteristics of the material itself, the design and manufacturing process of the lens are also crucial to its ability to withstand high temperatures. High-quality zinc selenide lenses usually use precision polishing and coating processes to improve their surface finish and light transmittance. These processes can reduce the heat absorption of the lens under laser irradiation, thereby reducing the temperature of the lens and further enhancing its ability to withstand high temperatures.
In addition, some additional measures can be taken to further improve the stability of zinc selenide lenses at high temperatures. For example, by optimizing the cooling system of the laser welding machine, the operating temperature of the lens can be effectively reduced. At the same time, when installing the lens, it should be ensured that it is firmly fixed to avoid deformation or damage to the lens due to vibration or impact during the welding process.
In summary, the reason why laser lens zinc selenide can withstand high temperatures without deformation during laser welding is mainly due to its excellent material properties, sophisticated design and manufacturing process, and additional cooling and protection measures. The combined effect of these factors makes zinc selenide lenses an indispensable and important component in laser welding machines, providing a strong guarantee for the high quality and high efficiency of industrial manufacturing.
