CDU Piping Laser Welding System | Low Distortion Cold Plate Welding | AI Server Cooling Welding Solution

Empowering AI Infrastructure with Hailei Laser’s Precision QCW Technology

Core Selling Points: Overcoming Liquid Cooling Manufacturing Challenges

• Ultra-Low Thermal Input & Zero Deformation: Traditional continuous lasers often cause severe thermal warping on ultra-thin cold plates. Our QCW technology delivers high peak power with low average heat, drastically shrinking the heat-affected zone (HAZ). This ensures that thin-walled aluminum or copper micro-channels maintain their precise tolerances and flatness, eliminating post-weld straightening processes.
• Hermetic Sealing for High-Pressure Reliability: Liquid cooling systems must withstand extreme pressure and thermal cycling. The QCW laser creates deep, uniform, and highly dense weld seams with zero porosity. Our systems are validated to pass rigorous helium leak tests (achieving >99.5% pass rates) and sustain pressures well above 1.6MPa, guaranteeing zero leakage throughout the server's lifecycle.
• Intelligent Seam Tracking & Process Stability: The CDU piping system involves complex spatial curves and tight spaces. Integrated with high-precision CCD vision systems and real-time melt pool monitoring, our workstation dynamically adjusts the welding path and parameters. This intelligent feedback loop ensures flawless fusion even when facing slight assembly gaps or material inconsistencies.
