High-Precision Diode-Fiber Hybrid Laser Welding Head for Aluminum Battery Sealing

The Hanwei Diode-Fiber Hybrid Laser Welding Head integrates diode laser (915nm) and fiber laser (1064nm) technologies to realize coaxial combination. This pioneering solution performs exceptionally well in welding thick metals and those with high reflectivity (such as gold, silver, copper and aluminum), boasting outstanding absorption performance that reduces sparking to a minimum, while creating high-quality welds with remarkable surface smoothness.

Tailored specifically for the seal welding of power battery covers, this system generates smooth, defect-free weld joints. It not only effectively avoids the risks of battery leakage and explosion, but also greatly enhances welding efficiency.

• Eliminates spatter and liquid leakage issues
• Significantly reduces weld defects and imperfections
• Produces aesthetically pleasing, smooth welds for power battery top covers
• Enhances overall welding efficiency and productivity
• Superior performance for medium-thin plates, aluminum, and high-reflective materials

• Reduction of welding defects with improved efficiency
• Full wavelength range coverage for versatile applications
• Ideal solution for power battery top cover welding
