Product Description
D28 Heavy Duty Precision Welding Table for Industrial Fabrication Projects
The D28 Heavy Duty Precision Welding Table is a professional modular 3D welding fixture system designed for heavy industrial fabrication, structural steel welding, mechanical assembly, and robotic welding stations. Built with industrial-grade cast iron or high-strength steel box structure, this D28 jig table delivers ultra-high flatness, extreme load capacity, and full 3D clamping flexibility to replace traditional custom welding jigs. It is widely adopted by steel fabrication factories, machinery workshops, new energy manufacturing, and vocational training centers worldwide.
Compared with ordinary welding plates, the D28 modular system eliminates repeated jig making, reduces production errors, improves welding consistency, and drastically shortens setup and changeover time for batch production.
Product Parameters
| Aspect | Cast Iron | Q355 (Structural Steel) |
| Material Category | Iron-carbon alloy with high carbon content (2-4%), produced by casting. | Low-alloy high-strength structural steel (GB/T 1591-2018), produced by rolling/forging. |
| Common Types | Gray Iron, Ductile Iron. | Replaces the old grade Q345. |
| Key Composition | High carbon (2-4%), high silicon (1-3%), low manganese (0.1-1%). | Low carbon (≤0.24%), low silicon (≤0.55%), manganese (1.0-1.6%), with microalloys (Nb, V, Ti). |
| Mechanical Properties | - Tensile Strength: 120-400 MPa (low) | - Tensile Strength: ≥355 MPa (actual: 470-630 MPa) |
| - Brittle, low toughness | - High toughness, impact resistance | |
| - High hardness (HB 150-300) | - Moderate hardness (HB 130-180) | |
| - Poor weldability. | - Excellent weldability. | |
| Manufacturing Process | Casting (molten metal poured into molds). Ideal for complex shapes. | Hot/cold rolling, forging. Easy to cut, weld, and machine. |
| Applications | Engine blocks, machine tool bases, pipes, cookware (e.g., cast iron pans). | Structural frameworks (buildings, bridges), ships, pressure vessels, machinery. |
| Advantages | Cost-effective, wear-resistant, good vibration damping. | High strength-to-weight ratio, ductile, suitable for dynamic loads. |
| Limitations | Brittle, difficult to machine post-casting. | Requires corrosion protection in harsh environments. |
Surface Treatment
All D28 welding tables adopt professional nitriding treatment (top export standard), which forms a deep hardened layer on the table surface and inner hole walls.
Surface hardness: HV600-1000
Integral hole hardening: No hole expansion after long-term pin insertion
Salt spray and rust resistance for long-term workshop use
No paint coating — paint will burn under welding high temperature and cause electric arc breakdown.
3D Full-Space Clamping Advantage
Different from ordinary single-sided welding plates, our D28 welding table adopts five-sided hole design (top + four vertical sides fully perforated).
- Realize X/Y/Z three-dimensional positioning
- Clamp irregular frames, cabinets, brackets, pipe structures in all directions
- No dead angle for clamping and assembly
- Support multi-angle welding and overturning assembly
After-Sales Support
- 12-month full warranty for the table body
- Lifetime technical support
- Online installation guidance and fixture layout solution support
- Custom size and structure service available
