Multi-Head U-Rib Welding Machine
Request a Quote
Multi-head u-rib welding machine is a high-efficiency multi-torch system designed for simultaneous fillet welding of multiple U-ribs on large structural panels. Assembled panel units are secured on a welding platform with adjustable tilt angles. The welding system utilizes a mechanical seam tracking device to ensure reliable torch alignment, while the motorized gantry travels at infinitely variable speeds via AC frequency control. This setup allows for the simultaneous welding of both sides of multiple U-ribs.

Key Features
-
- Process Flexibility The system can be configured for either MIG (GMAW) or SAW (Submerged Arc Welding) processes based on project requirements.
-
- Versatile Workholding The welding platform can be equipped as either a flat worktable or a specialized anti-deformation jig (cambering frame) to control thermal distortion.
-
- Automated Tracking Integrated mechanical trackers maintain consistent torch positioning along the ribs, ensuring uniform weld quality across the entire panel.
