Advanced Blue and Infrared Laser Technology for High-Reflectivity Metal Welding
The JUYI Blue-Red Hybrid Laser Welding Machine combines blue laser and infrared laser technologies to provide an advanced welding solution for copper, aluminum, brass, and other highly reflective metals.
The system integrates a 455 ± 10 nm blue laser with 400–600W output power and a 1070 ± 10 nm infrared laser system supporting up to 4000–6000W power. By combining the different absorption characteristics of blue and infrared wavelengths, the system provides improved energy coupling, stable melting, and efficient heat input for challenging metal welding applications.
Compared with conventional infrared fiber laser welding, the blue-red hybrid approach is particularly advantageous for materials with high laser reflectivity, making it an ideal solution for copper welding, battery manufacturing, busbar welding, electrical components, EV motors, and new energy applications.
How Does Blue-Red Hybrid Laser Welding Work?
The system combines two different laser wavelengths that interact with metal in different ways.
Blue Laser — 455 ± 10 nm
The shorter-wavelength blue laser provides significantly improved absorption characteristics for highly reflective metals such as copper.
Its main role is to improve laser-to-material energy coupling and help establish a more stable welding process.
Infrared Laser — 1070 ± 10 nm
The high-power infrared laser provides the primary energy required for efficient melting and deep penetration welding.
The infrared laser system supports a maximum allowable power range of 4000–6000W, providing substantial energy capacity for high-power industrial welding applications.
Hybrid Welding Process
Blue Laser → Improved Absorption → Infrared Laser → High-Power Melting → Stable Molten Pool → High-Quality Weld
The coordinated use of blue and infrared laser energy allows the system to address some of the limitations associated with conventional infrared laser welding of highly reflective metals.
Key Advantages
1. Excellent for Copper Welding
Copper has high thermal conductivity and high reflectivity to near-infrared laser light, making conventional laser welding more challenging in certain applications.
The 455 nm blue laser provides better absorption characteristics for copper, allowing laser energy to be coupled into the material more effectively.
This makes the JUYI Blue-Red Hybrid Laser Welding Machine particularly suitable for:
- Copper busbars
- Copper terminals
- Copper wires
- Copper connectors
- Copper sheets
- Electrical contacts
- Battery components
2. Blue Laser with 400–600W Output
The system is equipped with a 455 ± 10 nm blue laser with an output power range of 400–600W.
The blue laser is designed to enhance energy absorption when welding high-reflectivity materials, helping improve process stability and welding efficiency.
3. High-Power Infrared Laser
The infrared laser operates at 1070 ± 10 nm and supports a maximum allowable power range of 4000–6000W.
The high-power infrared laser provides the energy required for high-speed melting and deep penetration, making the system suitable for demanding industrial welding applications.
4. Improved Energy Coupling
The combination of blue and infrared wavelengths allows the laser energy to interact with the workpiece more effectively.
For highly reflective metals, improved energy coupling can help achieve:
- More stable laser absorption
- More consistent melting
- Better molten pool control
- Improved welding repeatability
- Higher process efficiency
5. Stable Molten Pool
One of the key challenges in high-power copper welding is maintaining a stable molten pool.
The blue laser helps improve initial energy absorption, while the infrared laser provides high-power energy for continuous melting.
The combined energy distribution can help create a more controlled and stable welding process.
6. High Welding Efficiency
The combination of 400–600W blue laser power and a 4000–6000W infrared laser power capacity provides a high-energy welding platform for industrial production.
The system is suitable for applications requiring:
- High welding speed
- High penetration
- High production efficiency
- Stable continuous welding
- Repetitive industrial processing
Actual welding performance depends on material, thickness, joint configuration, laser parameters, and process conditions.
