Mastering High-Reflectivity Materials with Hailei Laser

In the rapidly evolving sectors of AI computing and new energy vehicles, liquid cooling cold plates are critical for thermal management. However, manufacturing these components from copper and aluminum has historically been plagued by high reflectivity, leading to unstable welding, severe spattering, and porosity. Hailei Laser proudly introduces our revolutionary Red-Blue Composite Laser Cold Plate Deep Penetration Welding Equipment. By combining the high absorption rate of blue light with the deep penetration capability of red light, our proprietary High-Reflectivity Material (Copper/Aluminum) Cold Plate Spatter-Free Laser Welding Process completely redefines the manufacturing standards for liquid cooling systems.

Core Selling Points: Unmatched Stability and Quality

Buyers in the high-end manufacturing sector demand flawless hermetic sealing and structural integrity. Our dual-wavelength composite laser system is engineered to overcome traditional physical limitations:

Spatter-Free Welding via Dual-Wavelength Synergy: The core innovation lies in the synergistic effect of red and blue lasers. Blue light boasts an absorption rate of over 47% for copper, rapidly melting the surface and forming a stable initial molten pool. Subsequently, the red light, with its superior power density, drives the deep penetration welding. This dual-action completely suppresses the violent metal vaporization that causes spattering, resulting in a perfectly smooth, aesthetically pleasing weld seam.
Deep Penetration with Minimal Thermal Distortion: Cold plates feature extremely thin internal flow channels (often below 0.1mm). Our composite laser precisely controls the heat input, ensuring deep and uniform weld penetration without melting through the internal ribs. The narrow heat-affected zone (HAZ) guarantees zero thermal deformation, maintaining the strict dimensional tolerances required for high-pressure liquid cooling environments.
Zero-Porosity Hermetic Sealing: The stable molten pool dynamics facilitated by the blue laser pre-heating effectively eliminate trapped gases. This results in highly dense, porosity-free welds that easily pass rigorous helium leak tests, ensuring long-term reliability and preventing catastrophic coolant leaks in AI servers or EV battery packs.
