At present, the global power battery industry has market demands for large capacity, high energy density, durable, ultra-fast charging, and high profits, which also put forward higher performance requirements for our large-scale photonic lasers.
It is well known that spatter affects the appearance, performance and safety of products and has a significant negative impact on product optimization. Research by Han’s Laser has shown that fiber lasers are prone to localized overheating on the surface of the small hole wall due to strong focusing and short wavelengths, poor adaptability of welding parameters and stability of the molten pool, which leads to spattering.
To prevent spattering and improve the welding effect, Han’s Laser initiated the variable spot project and developed beam-shaping lithography (the center ring beam and the outer ring beam can be independently controlled), which can be arbitrarily combined. The different spot modes can be used in different application scenarios to effectively prevent spattering generated during the welding process. Through unremitting efforts and scientific research, Han’s Laser launched a new ABS series product-single mode variable spot fiber laser.
Features of The Single Mode Variable Spot Fiber Laser
The product utilizes a single-mode annular beam of 14/100um for welding, resulting in a well-formed weld joint. It offers a low heat input while maintaining excellent stability and a high yield rate. The failure rate is below 0.1%, significantly outperforming the conventional laser’s 2% failure rate.
High power stability
The Single Mode Variable Spot Fiber Laser uses phosphide fiber without the photon darkening phenomenon to achieve stable output power in the performance of stable passive components. It provides a reliable guarantee in the welding process for customers.
The scientific and efficient power management system researched and developed by Han’s Laser, the independent packaging pump with a high conversion efficiency, low-loss fiber optic devices, and the gain fiber with high-efficiency optical-to-optical conversion scheme.
High reflective capacity
It is mainly reflected in the high-power anti-return devices, software warning and its special structural design, in the welding and cutting of copper applications to achieve fast speed, and smooth cross-section of the application effect. This ensures that customers can enjoy an excellent product experience during the processing of anti-high-reflection materials.
Platform monitoring and control system:
With real-time monitoring and power feedback functions, the system can be used for status monitoring, laser energy control, safety protection and other monitoring function modules of high-power lasers. It significantly improves product quality, safety and performance.
Superior beam quality control technology
Han’s Laser unique beam quality control technology enables a complete set of solutions to meet application scenarios from Gaussian to flat-top beams, with the added benefit of protecting the cutting nozzles of cutting machines.
It is suitable for welding in a variety of industries, such as new energy batteries, automotive industry, hardware furniture, construction machinery, construction industry, in addition to laser cleaning, laser cladding and laser quenching.
Han’s Laser has developed a unique single-mode variable spot and central beam control technology that can effectively inhibit spattering during the welding process, reaching the international leading level. The single mode variable spot fiber laser can weld different parts of the power cell quickly and with high quality because it has good weld shaping effect, low heat input, stability and high efficiency.
