QUANT STEELFAB 360: Robotic Beam Assembly and Welding with Integrated Rotation
QUANT STEELFAB 360 is a production-ready robotic system with the same model-driven assembly and welding workflow as QUANT STEELFAB. The difference is the transition between beam setups. After finishing one setup, the operator selects the next setup in the software; the integrated rotator moves the beam to the required angle. This removes crane-assisted turning between setups. Loading, unloading, production supervision, and application-specific checks remain part of the workshop process.
Capabilities:
- Tekla Job Simulation
- Scanner-Guided Assembly
- TouchSense Before Welding
- Operator-Initiated Beam Rotation
The Process
The same model-driven assembly and welding workflow in both systems. The difference is how the beam moves to its next setup.
- 01
Select & Simulate
A Tekla engineer selects beam assemblies in the Quant plugin. Quant software simulates the job and reports the component count and estimated assembly and welding time. These are simulation estimates, not guaranteed production cycle times.
- 02
Measure & Check
Scanner measures the beam position and dimensions and matches its point cloud to the 3D model. Once at the start of the job, it scans the parts tables, checks outlines and thickness, and reports missing required parts or thickness mismatches. Unrelated parts are ignored.
- 03
Review & Release
The software calculates a transformation of the measured beam and part coordinates. The operator reviews the green, yellow, and red match overlay and selects Continue to release the transformed coordinates to the assembly robot. The colors indicate degree of match, not universal pass/fail thresholds.
- 04
Assemble & Weld
The robots perform fit-up, tack welding, and finish welding for supported components. TouchSense locates the weld before the welding pass. The current configuration does not continuously track the seam during welding or correct the weld path from a laser scan.
Operators review the match and choose whether to continue; they do not manually edit component placement. A supervisor or production engineer reviews exceptions that require an engineering decision. Supported versions and export requirements are specified during project engineering.
Key Advantages
Redefining efficiency in structural steel fabrication
No-Code Operation
The software prepares tasks for supported beams without manually teaching every new beam. Engineers and operators still review job data, weld settings, and exceptions.
Measured Assembly Coordinates
The software calculates assembly coordinate transformations from measured geometry. The operator reviews the match and selects Continue before the coordinates are released.
Integrated Setup Changes
The operator initiates the next setup and the rotator repositions the beam. The crane is not needed for turning between setups; workshop handling and supervision remain necessary.

Technical specificationsBeam profiles
The standard supported beam length is 3,000–12,000 mm for the listed profile types. Width and height refer to the profile cross-section.
| Main beam profile | Standard length (mm) | Width (mm) | Height (mm) |
|---|---|---|---|
I- and H-beams | 3,000–12,000 | 160–400 | 160–650 |
U-channels | 3,000–12,000 | 180–400 | 100–300 |
Square and rectangular hollow sections | 3,000–12,000 | 100–300 | 100–400 |

Added parts
Supported added-part dimensions are 120–700 mm long, 80–500 mm wide and 4–40 mm thick.
- Flat plates
- L profile
- U profiles
- Square tubes
Suitability for a particular added part depends on its shape, material, thickness and selected gripper.
Cell footprint
Both models have the same footprint, including protective fencing.

- 21,000 × 6,700 × 3,000
- Extended tracks · beams up to 14 m
- 23,000 × 6,700 × 3,000
Additional clearance for beam loading and unloading, crane movement and service access is determined for the customer's site.
Welding scope
The system supports corner and t-joint configurations with horizontal and vertical welds.
Fillet weld leg size
- Single pass
- 3–6 mm
- Multiple passes
- 8–14 mm
Weld access and the applicable procedure are reviewed for each part.
Operator-Initiated Automatic Beam Repositioning
The operator selects Next setup in the software. The integrated rotator then moves the beam to the angle required for that setup. This replaces crane-assisted turning between setups; loading, unloading, supervision, and application checks remain part of the workshop process.
