It enables fully automatic workflow with no-manual transfer, realizing one-stop closed-loop production from raw materials to finished goods. High-precision laser cutting produces smooth, burr-free and distortion-free cuts, meeting dimensional accuracy requirements for ultra-thin sheets. Magazine-type auto-feeding supports bulk storage and precise auto-alignment, avoiding offset, missing or mis-fed parts caused by manual loading. Reliable spot welding secures stainless-steel and copper substrates against shifting during processing to ensure structural stability. The embedded HD industrial vision system identifies dimensional errors, flaws, cold and missing welds, enabling in-line quality control and automatic defective-part sorting. The final laser edge-sealing welding delivers narrow heat-affected zone, compact uniform seals and excellent airtightness. It stably preserves the internal vacuum of vapor chambers, securing heat-dissipation performance and service life at source.   Regarding mass-production reliability, the standard-built anti-static system reduces electrostatic interference to avoid substrate breakdown and dust adsorption, ensuring production cleanliness and safety. Its intelligent anomaly-monitoring system monitors machine status, station conditions and material supply in real time.

However, copper material exhibits reflectivity exceeding 95% for near-infrared lasers (1064nm), causing frequent issues including excessive porosity, severe spattering, and poor weld formation. One power battery manufacturer reported porosity rates of 8-12% in aluminum casing to copper tab welding, resulting in cell yield rates of only 87%—far below the industry standard of 95%. Technical Principles of Dual-Wavelength Hybrid Welding United Winner Laser's self-developed multi-wavelength coaxial hybrid welding head combines fiber laser (1070nm) with diode laser (915nm/940nm) through spatial beam combining. The shorter wavelength laser preheats to reduce material reflectivity, while the main welding laser achieves deep penetration keyhole effect, improving energy coupling efficiency to over 30%. Measured data shows copper welding spatter particle diameter reduced from 150-200μm in traditional processes to 20-30μm, with porosity controlled within 0.5%. Critical Process Parameter Windows For copper-aluminum overlap welding of 0.3-2.0mm thickness, recommended welding speeds are 200-300mm/s, laser power ratio (fiber:diode) of 7:3 to 8:2, and defocus of +2 to +4mm (positive defocus expands spot size, reducing power density). Shielding gas uses high-purity argon (≥99.999%), flow rate 15-25L/min, with side-blowing angle of 30-45° effectively suppressing plasma shielding effects. Welding Quality Verification and Process Monitoring United Winner Laser's integrated Real-time Weld Depth (RWD) detection system achieves micron-level precision in penetration online monitoring through optical coherence tomography. The system captures keyhole depth fluctuations at 10kHz sampling frequency, with AI algorithms real-time identifying precursors of pores and lack-of-fusion defects. One leading power battery customer reduced welding station defect escape rate from 3.2% to 0.15% after implementation.

The main components of a single cell include bipolar plates, electrode frames, electrodes, and membranes. Currently, the mainstream sealing methods for flow battery stacks in the industry include hot-melt sealing, dispensing, fluororubber cord sealing, and face sealing. These methods not only have high requirements for raw materials and high process costs but also suffer from unstable reliability. As the sealing adhesive is prone to aging, the risk of leakage increases, which seriously affects the battery's service life.     As a leader in China's laser welding field, UW Laser relies on 20 years of process technology accumulation in the vertical laser welding sector. By independently developing laser welding as a sealing method for flow batteries, it has solved the hidden problems caused by traditional methods. After plastic laser welding, the sealing performance is equivalent to (or greater than) that of the base material, providing a brand-new technical route for industry applications.   Compared with traditional sealing methods, laser welding has the following advantages:   1. It can achieve high-strength sealing effect, effectively preventing liquid leakage and ensuring durability and reliability. 2. It can achieve high-precision welding, showing good adaptability to the sealing of complex-shaped and small-size components. 3. Compared with traditional welding, laser welding has a smaller heat-affected zone, which can reduce thermal damage to surrounding materials. 4. Laser welding is easy to realize automatic control and mass production, improving production efficiency and quality stability. 5. For applications involving certain special materials or with special requirements for sealing materials, laser welding may have more advantages.   As the "dual-carbon" objectives accelerate, the long-duration energy storage market is experiencing explosive growth. Flow batteries, a highly promising technology in this field, have achieved a critical breakthrough in green manufacturing through the innovative application of laser welding. This technology not only enhances production efficiency but also promotes the industry’s transformation toward sustainability by eliminating chemical pollution risks associated with traditional processes. With deepening technological innovation and industrial collaboration, the large-scale deployment of flow batteries is accelerating.   03 Collaborative Innovation: Shaping a Green Energy Storage Ecosystem Together   Taking this award as a new starting point, UW Laser will continue to deepen the innovative application of laser welding technology in the green energy sector.
