    Advantages

    While conventional industrial lasers typically offer only high power, and existing specialized lasers may provide high power and high beam quality, the SDL-10000-CW introduces a third, irreplaceable advantage: high dynamic beam shaping frequency. This feature is a core differentiator for welding steel, aluminum alloys, and die-cast aluminum parts with thicknesses over 10mm. Its dynamic beam shaping frequency is an impressive four orders of magnitude higher than current solutions, enabling it to solve complex welding problems.

    The output parameters of the software-defined laser can be freely configured to produce any desired laser shape, providing exceptional flexibility for your specific needs.

    Advanced Laser Welding
    • Materials
      Ideal for high-reflectivity, high-thermal-strength, and high-melting-point materials such as aluminum alloy, high-temperature alloys, and high-strength steel. It also excels at heterogeneous welding (stacking welding, butt welding, and T-welding) of metals with different thicknesses or materials, as well as thick metal welding (10-20mm high-strength structural steel, aluminum/copper alloys up to 10mm) and for the high-speed welding of extremely thin materials, such as lithium battery electrode materials and fuel cell bipolar plates.
    • Typical Scenarios
      Welding high-strength low-alloy steel pipelines, extending the service life of wind turbine tower welds, high-speed single-pass welding of ship deck steel, and welding aluminum and die-cast aluminum parts for new energy vehicles. Other applications include high-speed welding of motor hairpins and high-speed welding of battery tabs.
    • Key Advantages
      Real-time control of beam shape, high-speed orientation, and spot focus without any moving parts.

    This software defined fiber laser stands out with its multiple advantages, including a high power of 10kW, a high beam quality of 1.2 times the diffraction limit, and a high dynamic shaping frequency of 10MHz. These features enable a definable, orderable, and switchable laser spot morphology with a scannable focus.

    The high beam shaping frequency is a core, irreplaceable advantage in metal welding, as it solves the welding challenges of steel, aluminum alloys, and die-cast aluminum parts with thicknesses over 10mm.

    The laser utilizes multi-channel phase control to achieve coherent synthesis for high beam quality output. By adjusting phase control parameters via high-speed FPGA circuits, the coherent position can be changed, allowing for spot transformation to any location and ultimately forming a spot of any shape.

    The 10kW laser's high beam quality enables deep thermal penetration, forming a stable weld pool for thicknesses over 10mm. This, combined with high-dynamic spot adjustment, significantly reduces spatter, pores, and cracks, resulting in consistently high-quality welds.

    The all-vector light field regulated laser maintains a beam quality close to the diffraction limit. It uses 24 optical fibers to simultaneously modulate a user-defined spot. Its stability is more easily maintained compared to traditional lasers.

    The service life of a fiber laser is determined by its pump source, which typically exceeds 100,000 hours. This laser utilizes a closed-loop control system and multiple sensors to perform real-time inference on key welding parameters, ensuring both short- and long-term process stability.
