    Product Details

    Equipment Introduction
    The LWF series fiber laser welding machine is different from traditional solid-state lasers that use crystal rods as the laser medium. The laser medium of fiber lasers is a long ytterbium doped double clad fiber, which is pumped by high-power multimode laser diodes. The generated laser has the characteristics of good beam quality and high energy, and has many unique advantages in the field of laser welding applications. This device has the following advantages:

    Good beam quality, high energy

    Suitable for high-speed and high-precision welding. Compared with traditional lamp pumped laser welding machines, it has a smaller divergence angle, offering great advantages in welding efficiency and weld seam effect.

    Compact size & portability

    Lightweight and compact, saving space and facilitating transportation. The laser transmission fiber can reach up to 15m, adapting to changing processing locations.

    Stable power & high reliability

    Energy fluctuations below 2% ensure stable laser welding quality. The average usage time of laser pump sources can reach over 50,000 hours, which is about 100 times that of lamp-pumped machines.

    High efficiency & low energy cost

    Electro-optical conversion efficiency is up to 30%. The overall power of FRZ-LWF500C is only 4000W (1/3 of a 300W lamp-pumped machine), reducing average energy consumption to about 1/10.

    Dedicated control system

    Uses specialized motion control software to guide the electric worktable along set trajectories. Offers arbitrary path editing and supports vibrating mirror worktables, robots, or line-following automation.
