Product Featured in This Video
- Oscillating Welding Path: Laser beam moves at 120-300 Hz to increase welding area and reduce heat concentration.
- Dynamic Power Compensation: Real-time laser power adjustment based on distance from the central path.
- Shielding Gas Protection: Inert gases form a vortex barrier to prevent oxidation and spatter.
- Reduced Heat-Affected Zone: Short-wavelength lasers minimize heat diffusion for copper collectors.
- High-Speed Welding: Rotating turrets enable dynamic welding at speeds >300mm/s with ±0.05mm accuracy.
- Beam Control Innovations: Single-mode annular beams with adjustable core/ring beams for deep penetration.
- Structural Optimization: Louvered collector design reduces laser penetration depth by 60%.
- Reinforced Ribs: Radial or circular ribs resist deformation during casing insertion.
