HanWei High Absorption Blue Laser Welding Head For Copper And Gold Processing

The blue laser welding head is engineered to solve the persistent challenges of welding highly reflective metals. Traditional infrared fiber lasers often struggle with low absorption rates, excessive spatter, and narrow process windows when welding copper or gold. Utilizing a 450nm blue light wavelength. Through an efficient beam transmission and focusing system, the blue welding head achieves stable keyhole welding for highly reflective materials, significantly reducing spatter and improving weld formation. It is an ideal choice for new energy batteries, 3C electronics, and semiconductor packaging.

The core advantage lies in superior material adaptability. High absorption means lower energy thresholds are needed to achieve penetration, drastically reducing the Heat Affected Zone (HAZ) and material deformation. Compared to infrared lasers, blue laser welding exhibits weaker plasma effects and negligible spatter, resulting in smooth, flat weld seams that require minimal post-processing. When combined with wobble welding functions, it further stirs the molten pool to release gases, ensuring weld density. The fully sealed optical structure prevents metal fume contamination, extending maintenance intervals.

This welding head is widely used in scenarios demanding high electrical and thermal conductivity. In the new energy sector, it is used for high-quality welding of battery busbars, copper bars, and tabs. In 3C electronics, it suits precision welding of mobile phone heat sinks, Type-C connectors, and micro-connectors. Additionally, in semiconductor lead frames, sensor packaging, and jewelry processing, the blue welding head achieves pore-free, crack-free joints thanks to its low heat input and high absorption rate.
