In the high-stakes manufacturing of EV battery packs and AI server cooling systems, a single microscopic leak can lead to catastrophic failures. Liquid cold plates demand flawless sealing, yet traditional welding methods frequently fall short. High-reflectivity materials like copper and aluminum are notorious for causing thermal deformation, excessive spatter, and internal porosity, severely impacting production yield rates.
Hailei Laser has cracked the code on these manufacturing bottlenecks. By introducing advanced beam shaping technologies, including Ring Mode (Annular Beam) and Red-Blue Composite Lasers, we have fundamentally transformed the liquid cold plate welding process. The Ring Mode effectively stabilizes the molten pool and suppresses spatter, while the Red-Blue Composite Laser ensures optimal absorption rates for highly reflective copper, significantly reducing internal porosity.
Furthermore, our precision welding systems focus intense energy into a microscopic spot, drastically minimizing the Heat-Affected Zone (HAZ). This low-thermal-input approach prevents thermal distortion, ensuring that thin-wall structures and intricate micro-channels maintain their exact dimensional tolerances. Designed for mass production, our systems also feature real-time closed-loop monitoring and OCT depth detection, guaranteeing 100% repeatability and seamless MES integration.
