Double Motor Blue Laser Welding Head with Reduced Spatter & Smoother Weld Surface
The double motor blue laser hybrid welding head is developed for welding medium-thick metals and structural components. It adopts adjustable beam oscillation technology for more uniform laser energy distribution. By flexibly adjusting the oscillation amplitude and speed, the welding head can adapt to workpieces of different thicknesses and weld types, greatly improving the flexibility of the welding process window.
Whether for copper, aluminum, or multi-layer laminated metals, the dual-swing design ensures a stable and efficient welding process, enabling a wider range of applications.
Applications
The double motor mechanism precisely controls the dynamic distribution of the laser beam on the weld seam, significantly reducing spatter generation. Less spatter not only keeps the welding area cleaner but also improves the internal density and surface uniformity of the weld. The weld seam is flat and continuous with a lower defect rate, delivering stable and reliable welding quality. It is especially suitable for precision parts and high-appearance-requirement welding applications, enhancing overall processing efficiency.
Double motor blue laser hybrid welding not only enables spatter-free welding but also delivers high-quality results including smooth weld seams, stable welding processes, and single-side welding with double-side forming. Its enhanced adaptability to wider weld gaps lowers pre-welding assembly requirements, greatly improving production efficiency and consistency. It is therefore an ideal solution for high-precision welding applications.
Blue laser achieves approximately 70% absorptivity in highly reflective metals. Compared with red lasers, it can achieve the same penetration depth at a lower power, reducing equipment power consumption and operating costs. Combined with double motor beam technology, the welding process is stable and spatter-free, producing smooth and delicate welds. It enables one-side welding with back formation, features wide weld gap adaptability, and tolerates certain assembly errors. This makes it ideal for mass production, improving yield rate and processing efficiency.

Performance Advantages
Thanks to the high absorption characteristic of blue laser, a stable molten pool can be formed with lower energy input during welding. The dual-swing blue laser hybrid welding head leverages this feature to achieve more precise heat control and more predictable welding results.
Lower energy input reduces the heat-affected zone, prevents overheating or burn-through of materials, and allows more flexible adjustment of welding parameters, making the welding process easier to replicate and stably implement.
