Brief: Discover the advanced HW Laser Welding Machine by Hanwei AMB, designed for precision welding of current collecting plates in cylindrical cells like the 4680 specification. This solution ensures low-resistance conduction, structural support, and efficient thermal management for optimal battery performance.
Related Product Features:
  • 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.
Faqs:
  • What are the key benefits of using the HW Laser Welding Machine for current collecting plates?
    The machine ensures low-resistance conduction, structural support, thermal management, and efficient electrolyte infiltration, enhancing battery performance and durability.
  • How does the oscillating welding path improve the welding process?
    The oscillating welding path at 120-300 Hz increases the welding area and reduces heat concentration, ensuring a more uniform and reliable weld.
  • What makes the HW Laser Welding Machine suitable for high-speed welding?
    The machine features rotating turrets with galvanometers, enabling dynamic welding at speeds >300mm/s with ±0.05mm accuracy, significantly cutting total welding time.
