一、Hidden Risks
（一） Risk of Dry Solder Joint
Traditional welding processes struggle to monitor weld penetration in real time, which can easily lead to weak weld joint connections. This may subsequently cause liquid-cooled plate leakage or heat dissipation failure.
（二）Welding Instability of High-Reactivity Materials
Highly reflective materials such as aluminum alloys and stainless steels tend to produce strong reflection during the welding process, which affects laser absorption rate and causes fluctuations in welding quality.
（三）Production Efficiency Bottleneck
Issues such as frequent model changeovers, time-consuming clamping, and cumbersome inspection processes can slow down the production pace and restrict capacity improvement.
二、Intelligent Solution: Laser Welding + OCT Inspection Integrated Technology
（一）Welding-Inspection Synchronization Technology
1.The NewOCT inspection system is integrated to achieve real-time visual monitoring of weld penetration (with an inspection accuracy of ≤10%).
2.Breakthrough Technology：
√ Axial resolution reaching the ≤0.02mm level for inspection.
√ Supports pre-welding height measurement and automatic focus calibration.
√ One-click switching of multiple process parameter recipes.
（二）Special Optimization for High-Reflectivity Materials
- Customized optical path design, capable of withstanding 8kW full-power continuous operation.
- Multi-waveform oscillating welding (linear, arc, sine, U-shaped, figure-of-eight, etc.), improving welding stability for high-reflectivity materials.
（三）Flexible Production System
- Patented Tooling Fixture: Enables rapid clamping of large-format liquid-cooled plates, supports multi-model collinear production, and shortens model changeover time by 50%.
- Synchronized Inspection and Welding: Eliminates the need for a separate subsequent quality inspection process and increases the single-piece production cycle by 30%.
三、Advantages of the Solution
（一）Cost Reduction & Efficiency Improvement：
Reduce labor, rework, and scrap costs.
（二）Quality Enhancement & Stability Assurance：
Avoid the risks of batch defects and product recalls.
（三）Flexible Adaptation：
Meet the needs of multiple fields such as new energy vehicles and ships.
