Vision-guided structural welding
9-Axis Cantilever Welding Robot Workstation
Bring robotic welding to long beams, stiffened panels and large fabricated assemblies.
A six-axis welding robot travels on three external linear axes. Global 3D recognition, local weld scanning and an integrated welding process database work together to generate welding paths for suitable components.
Discuss your workpiece →Explore the 22 m rail reference configuration below. Working range and equipment are configured around the workpiece and factory layout.
Reach the job from three directions
One robot. Three external axes. A larger working envelope.
The X axis moves the workstation along the ground rail. The Y crossbeam positions the cantilever across the work area, while the Z lift adjusts its vertical position. The robot's six joints orient the welding torch at the joint.
3,500 mm single-position welding width
0–1,800 mm welding height
Conceptual layout, not to scale. Rail length is not effective weld length.
End access, robot posture, work supports and the height datum must be checked in the final layout. Over-width workpieces require repositioning and re-location; reverse-side welds may require turning the part.

Mechanical Z stroke differs from the workpiece welding-height range. External-axis positioning accuracy differs from robot repeatability and finished weld accuracy.
From recognition to welding
A coordinated vision and welding workflow.
The operator interface runs on an industrial PC. The system combines measured weld coordinates with the welding process database to generate a program for the recognized geometry.
Prepare & tack
Assemble and tack the workpiece on suitable supports. Confirm joint preparation, access and the required welding process.
Recognize globally
The global camera captures the work area and builds a 3D representation. Multiple parts can be recognized within the configured scene.
Scan locally
The robot moves the end-mounted vision system to selected nodes for more detailed joint positioning.
Generate the program
The system combines weld location data with the selected process parameters to create the welding sequence.
Validate & weld
Check the generated path and equipment setup, then run the weld cycle with the configured auxiliary functions.
Alternate work zones
Where the cell layout permits, prepare another zone while welding continues. Transfer finished parts and repeat the sequence.
Programming-free operation applies to supported geometry and validated process configurations. It does not remove the need for part preparation, calibration, process selection or path verification. Alternating zones require suitable separation and interlocks.

Global + local 3D vision
RVC-G52000 provides overall recognition at a 1,200–3,000 mm working distance, with a far field of view of 2,900 × 2,500 mm at 3,000 mm.
RVC-M2600 provides local scanning at 400–1,000 mm. Its field of view is 600 × 450 mm at 700 mm. Both camera models use Gigabit Ethernet and carry an IP65 rating in the supplied data.
Camera field of view is not workstation weld coverage. Surface finish, occlusion and the actual joint determine scan suitability.

TCP/IP communication connects the PC and equipment. The final control arrangement is selected around the cell layout and operating requirements.
Select by the joint, not only the outside dimensions
Check torch and camera access before selecting the cell.
Typical component families
H-beams, plate-rib assemblies, partitions and large structural subassemblies used in bridge, ship and machinery fabrication are relevant candidates.
Provide the actual weld locations and required torch orientations. Deep compartments, close ribs and tilted plates can restrict scanning and welding even when the overall component fits the nominal envelope.
Reference clearance guidance
The equipment solution gives the following plate height / spacing combinations for its standard torch arrangement. The included plate angle is specified as at least 70°. These are layout-screening values, not a guarantee for every joint.
| Plate height H (mm) | Spacing W (mm) | Vision access |
|---|---|---|
| 50 | 80 | External |
| 100 | 120 | External |
| 200 | 280 | Included |
| 300 | 340 | Included |

Plan the complete installation.
For equipment selection
- Part drawings, material, thickness and weld map.
- Largest and smallest components, weight and support arrangement.
- Weld positions, quality criteria and target output.
- Floor layout, loading routes and handling method.
For commissioning
- Foundation and rail alignment requirements.
- Power, cooling, shielding gas and compressed air.
- Fume extraction, arc screening and cell protection.
- Robot / camera calibration and representative welding trials.
The rail is transported in sections. Packing, assembly and lifting arrangements are confirmed against the final equipment layout.
Common configuration questions.
Does a 22 m rail mean a 22 m continuous weld?
No. Rail length is a mechanical layout value. Effective weld length also depends on travel limits, robot reach, orientation and end clearance.
Is the 500 kg rating the maximum workpiece weight?
No. It is the cantilever system load listed in the equipment data. Workpiece weight is assessed separately against the supports, fixtures and handling equipment.
Can all welds be completed without moving the part?
Not necessarily. Over-width parts may need repositioning and a new locating cycle. Reverse-side or obstructed joints can require turning or another setup.
How is production output determined?
Evaluate actual weld length, joint size, number of passes, scanning time, repositioning and loading time. Representative trials provide a more useful basis than a general metres-per-day figure.
