Description
Mobile Gantry Collaborative Welding Robot
The JISI Mobile Gantry Collaborative Welding Robot combines a 6-axis collaborative robot with a movable gantry system, providing extended welding coverage and flexible deployment for large and complex workpieces.
Unlike fixed robotic welding cells, the mobile gantry can be repositioned between different work areas, allowing one system to serve multiple welding stations. The gantry structure provides horizontal travel and vertical lifting, enabling the robot to reach different welding positions while reducing the need to frequently reposition large workpieces.
The system supports automated MIG/MAG welding and can be configured with arc tracking, laser seam tracking, welding positioners and customized fixtures according to specific production requirements. It is ideal for steel structures, large frames, construction machinery, heavy equipment and general metal fabrication.
With flexible configuration and engineering support, JISI provides customized robotic welding solutions based on customers’ workpiece dimensions, materials, weld joints and production requirements.
Product Features
- Mobile Gantry Design: Movable gantry structure enables flexible deployment across different welding areas without permanent fixed installation.
- Extended Welding Coverage: Horizontal travel and vertical lifting significantly expand the robot’s effective working range for large workpieces.
- Multi-Station Flexibility: One robotic welding system can be repositioned to serve multiple workstations and changing production requirements.
- Flexible Robot Positioning: The 6-axis collaborative robot provides flexible torch positioning for different weld joints and workpiece geometries.
- Consistent Welding Quality: Repeatable robot motion and controlled welding parameters help improve weld consistency and production efficiency.
- Intelligent Welding Options: Optional arc tracking, laser seam tracking and seam detection can be integrated for different welding requirements.
- Customizable Configuration: Gantry dimensions, robot models, welding equipment, positioners and fixtures can be customized according to the application.
