Overview
Steel fabrication shops face consistent challenges: skilled welder shortages, heavy workpieces, repetitive joint geometries and tight delivery schedules. CBOXTEC steel structure welding robot solutions address these issues with collaborative welding arms and mobile welding carts designed for H-beams, box columns, trusses and base plates.
Typical Applications
- H-beam and I-beam welding
- Box column and built-up section assembly
- Truss and bracing connections
- Base plate and anchor bolt plates
- Stair and platform frames
Recommended Models
| Application | Model | Payload | Reach | Key Advantage |
|---|---|---|---|---|
| Large H-beams / box columns | CTC020-HJ2027 | 20 kg | 2027 mm | Long reach, heavy torch |
| Medium frames and brackets | CTC015-HJ1464 | 15 kg | 1464.3 mm | Multi-process, compact |
| Small connections and fixtures | CTC006-HJ1460 | 6 kg | 1460.7 mm | Fast setup, economical |

Key Features
Long Reach for Large Weldments
CTC020-HJ2027 delivers 2027 mm reach and 20 kg payload, reducing repositioning on H-beams and box columns up to 2 meters long.
Hand-Guide Teaching
Welders teach new joints by guiding the torch, cutting programming time from days to minutes for high-mix structural work.
Mobile Welding Cart Option
Move the robot to the workpiece instead of moving heavy steel. Pre-integrated cart includes power source, wire feeder and gas cylinder.
Multi-Pass Welding Support
Stable repeatability of ±0.05 mm and heavy torch capacity support multi-pass fillet and groove welds on thick-walled sections.
Case Studies
Steel Frame Job Shop in Southeast Asia
A structural steel fabricator replaced two manual stations with one CTC020-HJ2027 welding cart for H-beam sub-assemblies.
Frequently Asked Questions
The CTC020-HJ2027 is the most common choice for H-beams, box columns and trusses because of its 2027 mm reach and 20 kg payload. For smaller brackets and connections, the CTC015-HJ1464 is a cost-effective alternative.
Yes. CBOXTEC welding carts let you wheel the robot to the workpiece, making them ideal for job shops where workpieces are too large or heavy to move into a fixed cell.
With proper power-source matching, CBOXTEC CTC-HJ arms handle structural steel from 3 mm thin brackets up to 20+ mm thick-walled H-beams and box columns using multi-pass welding.
Most simple H-beam welds can be taught in 15–30 minutes using hand-guide teaching. Complex multi-pass joints may take 1–2 hours depending on fit-up and quality requirements.
