Collaborative Robot Laser Welding System + 6kW Laser Source – Engineered for 6mm Plate Welding

KEYGREE GROUP CO., LTD. – Your Partner in Advanced Welding Automation

 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
