Laser Hybrid Welding: Red & Blue Laser
Red and blue laser hybrid welding solves the process bottleneck of non-ferrous metals: the blue laser’s high absorption preheats the material, raising red-laser energy coupling for stable, low-spatter, low-porosity welds — built for batteries, motors and electronic packaging.
BLUE 455nm
Copper absorption ×11.9 vs near-infrared.
RED 3000W
Red-laser waveband, expandable to 15 kW.
COPPER 6mm
Max welding capacity on copper.
±2% / 24H
Power stability over a full shift day.
Highlights
- Blue laser (455nm) absorption on copper is ×11.9 and on gold ×60.2 versus conventional 1064nm near-infrared lasers — the preheat that makes non-ferrous welding stable.
- Red and blue hybrid light-field enhances infrared absorption (×3) with stable heat-conduction and deep-melting welding combined.
- Reduced spatter, reduced porosity and improved weld-seam forming on high-reflectivity alloys.
- Solves the industry bottleneck: welding of non-ferrous metals for batteries, motors and electronic packaging.
Applications
- Battery cells, tabs and busbars in EV manufacturing.
- Electric motor and e-drive joining on copper and aluminum.
- Electronic packaging where conventional red-laser welding is unstable.
- High-reflectivity alloy welding across non-ferrous fabrication.

Frequently Asked Questions
Why is copper so hard to weld with a normal laser?
Copper reflects most near-infrared laser energy and its absorption shifts with temperature, causing spatter and porosity. The blue laser’s 455nm light is absorbed ×11.9 better than near-infrared, preheating and stabilizing the melt pool for the red laser.
Which industries is hybrid welding built for?
Batteries, motors and electronic packaging — anywhere non-ferrous welding is the process bottleneck: cell tabs, busbars, motor windings and sensor packages.
What does the technical data mean for my parts?
Red waveband at 3000 W (expandable to 15 kW) with ±2% 24-hour stability and copper welding to 6 mm — send drawings for a process evaluation with the matching configuration.
Is this a production-proven process or experimental?
It is an engineered production process addressing known industry pain points: spatter, porosity and instability on high-reflectivity alloys.
