Blue Light Hybrid Laser Weld for Sealed Welding of Copper Liquid Cooling Plates
This system is designed for metals with high reflectivity such as copper, gold, and silver. The blue light wavelength interacts more efficiently with these materials, allowing energy to be absorbed more easily and supporting stable weld formation in demanding conductive applications.
The equipment integrates composite laser sources with an adaptive wobble function to improve energy distribution during welding. This helps stabilize the molten pool and improves seam consistency, making the process suitable for different joint types and structural variations.
Key Features
- Effective Welding for Copper-Based and Reflective Metals.
- Multi-Beam Integration with Adaptive Wobble Function.
- Reduced Energy Requirement for Stable Operation.
- Stable Welding Behavior with Low Spatter Output.
- Improved Energy Coupling for Strong Weld Formation.

Applications
The controlled interaction between laser energy and material reduces instability in the molten pool. As a result, spatter generation is significantly minimized, keeping the weld area cleaner and reducing the need for additional finishing work.
High absorption efficiency ensures that more laser energy is effectively transferred into the material. This leads to solid fusion, consistent weld depth, and reliable joint strength, especially in high-performance electrical and conductive applications.
