In the ever-evolving landscape of material technology, industries like new energy vehicles, lithium batteries, photovoltaics, and 3C (computers, communications, and consumer electronics) products are increasingly utilizing high-reflectivity materials such as copper. This surge in demand calls for advanced solutions to tackle the challenges associated with processing these materials. Han’s Laser has introduced an innovative solution: a blue-infrared hybrid laser welding system that redefines precision welding for high-reflectivity materials.

Why Combine Blue and Infrared Lasers?

Copper is a key material in precision electronic components due to its excellent conductivity. However, its low absorption of 1080nm infrared light poses a significant challenge in achieving efficient welding. Traditionally, increasing laser power has been the solution to improve penetration depth. Yet, this approach often results in excessive heat input, leading to spatter, inconsistent welds, and overheating beyond acceptable thresholds.

Blue lasers, on the other hand, exhibit a much higher absorption rate for copper, making them an ideal complement to infrared lasers. By combining blue and infrared laser sources, Han’s Laser hybrid laser welding machine balances heat input, ensuring a stable and efficient welding process while minimizing defects.

As power increases and the molten pool forms, the absorption rate rises dramatically.

The Principle Behind Blue-Infrared Hybrid Welding

The hybrid welding technology developed by Han’s Laser utilizes the advantages of both blue and infrared laser wavelengths. Infrared lasers provide the necessary depth of penetration, while blue lasers enhance absorption and stabilize the molten pool. This synergy results in:

Reduced Spatter: The optimized heat input eliminates the excessive splattering common in single-wavelength systems.

Consistent Weld Quality: Stable heat distribution ensures smooth, pore-free surfaces and visually appealing weld seams.

Improved Thermal Control: Controlled heat input prevents overheating, crucial for delicate electronic components.
