The D28 Modular Welding Table with interchangeable jigs is a heavy-duty 3D flexible fixturing system engineered for demanding custom fabrication work. Built around the standard Φ28mm H7 locating hole and a 100 mm × 100 mm grid pattern, this complete set lets you rearrange, swap, and reuse all locating blocks, angle boxes, V-blocks, and clamping components freely — eliminating the need for expensive single-purpose custom jigs. With an optional nitrided surface, Q355 steel or HT300 cast iron base, and strict flatness control, it ensures reliable repeat positioning, reduces weld distortion, and shortens changeover time. It is ideally suited for chassis, heavy frames, and robotic welding cells.
| Holes | Φ28mm H7 precision positioning holes arranged in a 100mm × 100mm grid; holes are present on the top surface and all four sides (five-sided welding table). |
|---|---|
| Material | Q345/Q355 steel or HT300 cast iron. The table surface undergoes artificial aging for stress relief and is precision-milled via CNC. Optional nitriding treatment (HV550–900) is available for resistance against weld spatter, wear, and deformation. |
| Flatness | Standard ≤0.1mm/1000mm; high-precision versions can reach 0.05mm/m, with even higher precision available for robotic welding applications. |
| Load Capacity | Heavy-duty models offer a static load capacity of 5–10 tons, suitable for thick plates and large-scale structural frames. |
| Positioning Tolerance | Hole-pattern accuracy of ±0.02 to ±0.05mm, ensuring stable, repeatable positioning. |

- Universal Interchangeability: All clamps and positioning components follow the unified D28 standard. Once a job is complete, components can be removed and reconfigured for the next setup, eliminating the need to fabricate dedicated, one-off jigs.
- Rapid Changeover: Skilled operators can reconfigure the tooling setup in just a few minutes — an ideal solution for high-mix production environments involving complex, irregularly shaped parts.
- Versatile Platform for Diverse Projects: A single platform can be used for a wide range of complex applications, including vehicle frames, machinery chassis, piping assemblies, structural components for construction equipment, automation frameworks, and robotic welding workstations.
- Repeatable Precision: The same tooling configuration can be reassembled with consistent dimensional accuracy, reducing the need for rework and minimizing the risk of welding-induced distortion.
- Reduced Tooling Costs: Unlike traditional, project-specific jigs — which are costly, time-consuming to produce, and often left idle after a single use — the D28 modular system offers long-term reusability.
Comparison with D16 Welding Tables: While the D16 system (featuring 16mm holes spaced 50mm apart) is best suited for sheet metal, small components, and precision light-duty applications, the D28 system is the preferred choice for heavy-duty tasks, large-scale components, thick plates, and complex heavy-duty structures.
Initial inspection after aging → First-article inspection following CNC machining → 100% inspection of flatness, hole spacing, and perpendicularity → Cleaning of finished parts and plugging of holes for protection.

- Daily: Use compressed air to clear weld spatter from the holes, and a copper brush to clean the positioning holes. Do not use strong acids or alkalis to wash the nitrided surfaces.
- Quarterly: Verify flatness and inspect locking pins for wear. Replace any pins that exceed wear tolerances (pins are consumable parts, whereas the table itself has a long service life).
- Long-term Storage: Apply anti-rust grease and cover with a dust-proof tarp. Avoid concentrating heavy loads on a single point for extended periods.
- Service Life: With proper use, a nitrided welding table can maintain its required precision for 8–12 years. Conversely, frequent rough impacts or failure to remove weld spatter will cause a rapid decline in precision within 2–3 years.
