6mm Plate Welding: The Automation Gap
Arc welding is too slow and causes distortion. High-power laser systems are costly and inflexible. Skilled welders are in short supply.
The Solution: Collaborative Robot + 6kW Laser + Digital Wire Feeder
KEYGREE’s fully integrated system combines a 6-axis collaborative robot, a 6kW fiber laser source, and a digital wire feeder (0.8-1.6mm) — with all welding parameters controlled through the wire feeder interface.
What It Delivers:
- Single-pass penetrationon 6mm carbon and stainless steel
- ±0.02mm repeatabilityfor consistent weld quality
- No safety fencing required— saves 30-40% floor space
- Hand-guiding programming— new operators productive in hours
