High-power fiber lasers are suitable for processing steel with an absorption rate of more than 50 percent , but are limited by the fact that highly reflective metallic materials reflect 90 percent or more of the near-infrared (NIR) laser radiation incident on their surfaces. In particular, the welding of yellow metals such as copper and gold with NIR lasers is limited by the fact that the low absorption rate means that a large amount of laser power is required to initiate the welding process. As metal processing technology continues to advance and user requirements continue to increase, lasers need to innovate in terms of cost and energy efficiency as well as the performance of the laser system. The market demand for efficient processing of highly reflective metals has inspired the development of blue high power laser technology and is set to open the door to new technologies in metal processing. The following is an introduction to the application of blue laser welding technology in the welding of highly reflective metal materials.
Copper's absorbcija of blue light is more than 13×(13 times) higher than infrared absorption, in addition, the absorption rate does not change much when copper melts, once the blue laser starts welding, the same energy density will make the welding continue, the blue laser welding has inherent good control and less defects, the result is fast and high quality copper weld, the wavelength of the laser of 450 nm on the processing efficiency of the copper material than the wavelength of 1μm With a propromiseing increase of beveik 20 times, the high-power blue laser offers quantitative and quality advantages over conventional near-infrared laser suvirinimas procesai.
Labai atspindintys metalai tokie kaip varis ir auksas sugeria 7 to 20 kartų daugiau in the blue light spectrum than in the infrared, and the solution lies in the use of shorter wavelengths of light in the blue light category for the industrial processing of non-monous metals. First, blue light has specific properties. Labai atspindintis metalinis medžiagos sugeria mėlyna šviesa at a aukštas greitis, kuris reiškia kad mėlyna šviesa turi a didžiulis privalumas for metalas apdirbimas labai atspindinčios medžiagos tokios as varis.
Antra, the absorbcija greitis daro ne keičiasi daug kai varis is ištirpsta. Kartą the blue laser starts suvirinimas, the same energy density will allow the welding to continue. Pagaliau, blue laser welding has inherly incely good control and lesser defects, and the result is fast and high-quality copper welds. Ruifeng fotoelektrinis lazeris fokusas on šešiolika metų iš tyrimų ir plėtros technologijos ir gamyba, su daug metų iš patirtis in lazeris įranga tyrimai ir plėtra, produktas technologija is brandus, produktas našumas is saugu ir stabilus. The company follows the business philosophy of "technological innovation, product innovation, service innovation" to provide customers with the best quality products and services.
Mėlyna sūpynės kompozitas suvirinimas technologija paprastai naudojamas akumuliatorius adapteris suvirinimas. Adapteris suvirinimas is an labai svarbu procesas in the power battery cell production process, play a role in connecting the cover plate and the role of the core, the quality of the weld directly affects the performance of the wholere cell, first of all, in order to ensure that the weld needs to reach a certain area of the overcurrent capacity, todėl reikės the weld to a tikras plotis iš the klijavimas paviršius. Antra, the weld should not leave any spatters, so as to avoid short-jungimas inside the battery due to the particle, which will affect the safety performance of the battery.
The above is the application of blue laser welding technology in the welding of high anti-metal materials, in general, the blue laser improves the welding speed, which can be directly translated into faster production efficiency, as well as minimize the production prastovos; the consistency of the weld quality can greatly improve the production yield rate; spatter-free and non-porous high-quality weld, as well as higher mechanical stiprumas ir mažesnis elektrinis varža, ir kiti unikalūs privalumai to praplėsti apimtis išskirti į procesą. Procesas diapazonas is išplėstas.
In papildymas, the blue laser can also perform šilumos laidumas suvirinimas modes, kurie yra ne įmanoma su infraraudonųjų spindulių lazeriais. As a modernus pažangus apdorojimas technologija, mėlyna virpesiai kompozitas suvirinimas technologija kūrybiškai sprendžia the laser processing problems in many industries, greatly improves the product quality of downstream customers, and will be plačiai used in new energy batteries, consumer electronics, motors, motors, transformeriai ir daug kiti laukai, rezultatas in reikšminga ekonominė ir socialinė nauda.
