Spatter-Free Blue Composite Laser Welding Machine for High-Reflectivity Materials

The blue light source collaboration is the core technical highlight of this equipment. Blue light (450nm) achieves over 60% absorption rate on copper, compared to only approximately 5% with traditional infrared lasers, fundamentally solving the "high reflection" challenge in copper welding. During composite welding, blue light preheats and activates the material while infrared laser achieves deep penetration and forming; their collaboration ensures both penetration depth and spatter avoidance. Test data shows that in 1.5mm purple copper butt welding, tensile strength can reach over 65% of base material, with weld porosity controlled below 0.5%. The equipment features an intelligent energy ratio control system that automatically adjusts blue/infrared power ratios according to material type and thickness, simplifying operational difficulty.
