Dual-Station Intelligent Laser Welding System For AI Cold Plates
Products Description
Cooling Plates Laser Welding
Hglaser Dual-Station Intelligent Laser Welding System for Cold Plates is engineered for laser seal welding of pure-copper cold plates and copper-to-stainless-steel cold plates, the system replaces conventional processes such as brazing and friction stir welding. It requires no brazing filler metal, streamlines production, lowers capital investment, and improves both yield and throughput. The system comprises a fiber laser with a core-ring beam, a motion platform, a loading, clamping and pressing mechanism, an inspection and positioning system, a water-cooling system, and a fume extraction unit.
| Filler Material | None required |
| Contamination Risk | Zero |
| Thermal Conductivity | Preserves base metal properties |
| Joint Strength | Equal to or exceeds base metal |
| Process Complexity | Automated, single-step |
| Cycle Time | 30-60 seconds per cold plate |
| Capital Investment | Moderate |
Features:
- Weld strength approaching that of the base metal
- 100% pass rate in leak-tightness testing
- Clean, unobstructed flow channels with no residual contaminants
- No distortion, blockage, leakage, or gas-induced bulging
- High throughput, intuitive operation, and an environmentally responsible process
Why This Matters for AI Cooling ?
- Pure coolant loops in AI servers are extremely sensitive to particulate contamination
- Filler metals can shed micro-particles that clog micro-channels in cold plates
- Galvanic corrosion between filler alloys and base metals accelerates in high-flow coolant environments
- Laser-welded joints maintain the full thermal conductivity of copper (≈400 W/m·K)
