Double Motor Blue Light Hybrid Welding Head for Reducing Welding Spatter on Copper

The double motor blue light composite welding head is designed for high-demand welding conditions of medium to thick materials. Its dual-swing spot structure can be flexibly adjusted according to the weld seam shape, material characteristics, and welding depth, allowing the energy to be evenly distributed in the weld area. This not only enhances welding stability but also significantly expands the process window. The adjustable spot enables the welding head to quickly adapt and maintain consistent processing quality when dealing with different thicknesses, various metal combinations, and special structural components. Therefore, it is widely applicable in equipment manufacturing, battery structural components, copper-aluminum connections, and various high-reflectivity metal welding applications.

The absorption rate of blue laser (wavelength-specific) in highly reflective metals such as copper and gold reaches approximately 70%. Compared with red laser, it achieves the same welding depth with significantly lower power input—reducing both equipment energy consumption and system configuration costs.

Dual-swing 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.

• Wide-area welding solution for medium and thick plates.
• Precise thermal control capability enabled by low absorption threshold.
• Significantly reduces spatter and optimizes weld quality.
• Dual advantages of ultra-high absorption rate and low power requirement.

The energy distribution characteristic of the dual-swing structure stabilizes the molten pool and ensures uniform flow of molten metal during welding, significantly reducing weld spatter at the source. Low spatter results in fewer metal particles generated during the welding process, cleaner weld exteriors, and reduced post-welding processing workload.

Meanwhile, this stable molten pool mode effectively prevents welding defects such as porosity and undercut, delivering smoother and more uniform overall weld profiles. This advantage is particularly prominent for industries with high requirements for weld appearance, such as consumer electronics structural components and motor copper part welding.

The absorption capacity of blue laser wavelength in highly reflective materials is far higher than that of traditional infrared laser, enabling the dual-swing blue laser hybrid welding head to achieve a lower energy absorption threshold. It can attain stable weld penetration with lower input power, making heat absorption and control by the material more efficient.

Processing advantages brought by the lower threshold include reduced heat-affected zone (HAZ), prevention of material collapse or burn-through, and easier setup and reproduction of welding parameters. This more controllable heat input capability makes it particularly outstanding when welding workpieces with significant thickness variations or high sensitivity to thermal deformation.
