Copper welding: stable, spatter-free seams.
A single-mirror retrofit brought ring-core performance to an existing welding laser. That means spatter-free seams and a wider process window for cost-efficient series production, with our partner BBW Lasertechnik.
In partnership with
Challenge
- Spatter from the Gaussian intensity peak
- Narrow focus window (±1 mm)
- Beam wobbling required to stabilize the seam
Result
- 3× larger process window
- Spatter-free, uniform seams
- Drop-in retrofit: installed in under 30 minutes
- Enables cost-effective series production
Upgrades an existing laser to ring-core performance, replacing an expensive ring-core laser with a simple retrofit.
Setup & conditions:
copper welding for battery applications, with BBW Lasertechnik. Comparison shows a standard Gaussian beam versus the 3D Ring-Core, each with and without wobbling.
