Welding Positioners
Servo-axis positioners bringing workpieces from 1 to 25 tonnes into the ideal welding position.
What the system does and how it is engineered
Welding in the correct position improves penetration, bead appearance and speed together. Robentex L-type and H-frame servo positioners run fully synchronized with robot motion, continuously presenting the part in PA/PB position.
- Capacity
- 1,000 – 25,000 kg
- Configuration
- L-Type / H-Frame
- Synchronization
- Fully coordinated with robot
Applications
- Transformer tank and cover welds
- Heavy chassis and boom groups
- Turntable cell integrations
Key Features
- Servo-driven precise indexing
- Axis management from robot controller
- Part-specific mounting interfaces
Systems delivered in the Welding Positioners family
9 m Gantry
Inverted-Robot Gantry Tray Welding System
Access to every inner and outer seam on trays up to 3,000 × 1,800 × 400 mm, with two L-type positioners alternating.
