Which model files drive welding robot programming?
Honglu’s model-driven welding mode imports STEP, IGS, and IFC files to create robot welding programs from structured 3D geometry. HOLU Technology software parses the model, extracts weld seams, matches process parameters, plans the trajectory, runs full-path collision detection, and starts welding through the robot workstation.
| Input | Honglu programming role |
|---|---|
| STEP | 3D model import |
| IGS | 3D model import |
| IFC | BIM-linked model import |
| Tekla Structures | Project modeling workflow across Honglu detailing |
| TCP/IP | Remote equipment control path |
This is drawing import welding built for steel structures.
Which workstation uses one-click model import?
The HLZZHJ-R-QJLX-12 workstation uses model import plus one-click start for structural steel robot welding. Honglu runs 2,000 units of this floor-mounted rail-guided robot welding workstation in-house for H-columns, roof beams, crane beams, flat right-angle welds, folded-angle welds, vertical fillet welds, and full-penetration welds.
| Verified specification | Value |
|---|---|
| Robot reach | 2,000 mm |
| Ground rail | 12,000 mm |
| Effective stroke | 10,630 mm |
| Welder | Megmeet Dex2 500MPR |
| Sensor | Mingtu/Weijing laser sensor |
This verified configuration makes model import a production welding function.
What happens after the software extracts weld seams?
After seam extraction, Honglu software matches parameters, plans the path, checks collisions, and controls the equipment remotely over TCP/IP. The full-stack development scope covers operating system, robot controller, point-cloud algorithms, and vision system, so the automated robotic welding system remains a Honglu-controlled production platform.
- Import STEP, IGS, or IFC.
- Parse steel geometry.
- Extract weld seams.
- Match welding parameters.
- Plan robot trajectory.
- Run full-path collision detection.
- Weld under programmed control.
This workflow links model geometry to the welding blueprint automation cluster.
When does model-free welding replace drawing import welding?
Model-free welding replaces drawing import welding when tack-welded components lack usable drawings or arrive as non-standard repair parts. Honglu’s HLDZXBHJ-R-QJLX-14-6 inverted cantilever robot welding workstation uses dual 3D stereo vision with Honglu air-cooled sensing and Beijing Jingwei line-scan hardware. A large-scene global camera scans the workpiece, reverse-models the point cloud, and generates the weld program without drawings. This blind-welding path covers bridge unit plates and other model-free components where teach-pendant programming blocks production flow.
How does model-driven programming support quality documentation?
Model-driven programming supports quality documentation by connecting geometry, welding procedure control, and repeatable robot execution in one data path. Honglu anchors this workflow in AISC, EN 1090-1, EN 1090-2, ISO 3834, UKCA, GOST-R, and Welding Procedure Qualification terminology. The same production system supports full-penetration welds, Grade 1 welds, fillet welds, root passes, filling passes, cover passes, NDT, and UT. For smart-manufacturing context, the verified June investor meeting news connects Honglu orders with manufacturing upgrades.
