The 1200×2400mm heavy-duty 3D welding table (featuring a D28 hole system) is a high-precision, modular, and flexible welding fixture system designed for precise positioning, clamping, and assembly of workpieces in 3D space (X, Y, and Z axes). It is widely used in heavy-duty welding applications including steel structures, construction machinery, automotive chassis, and rail transportation.
| Table Dimensions | Width 1200mm × Length 2400mm × Thickness 200mm (Top plate thickness: 25mm) |
|---|---|
| Hole Specifications | Hole diameter 28mm (D28); 100mm × 100mm grid spacing; hole position tolerance ±0.05mm |
| Flatness | ±0.1mm/m²; overall flatness ≤0.5mm |
| Material | Top Plate: Q355 (S355J2+N) low-alloy high-strength steel or HT300 cast iron |
| Structure | Fully welded with reinforcing ribs; stress-relief annealed to prevent deformation |
| Surface Treatment | Gas nitriding (wear-resistant, weld-spatter resistant, rust-proof, and high-temperature resistant) |
| Load Capacity | 2-3 tons (uniformly distributed); heavy-duty models up to 5 tons |
| Weight | Approx. 510-1116kg (cast iron models are heavier) |
- Tabletop: Features a full grid of D28 holes, serving as the primary working surface
- Four sides (200mm height): Each side features three rows of D28 holes, enabling clamping, positioning, and support from the sides to facilitate all-round, multi-angle welding
- Advantages: Irregular parts, enclosures, and frames can be clamped on five sides simultaneously without the need to flip or reposition the workpiece, resulting in high efficiency and minimal cumulative error
3D welding tables can be seamlessly joined using specialized positioning pins (T-locking pins), ensuring consistent flatness and hole alignment across the assembly. This allows for the creation of extra-large work surfaces, such as 2400×2400 mm or 2400×3600 mm configurations.
Ideal for: Extra-long and extra-wide workpieces, including large steel structures, construction machinery frames, rail vehicle bodies, and ship sections.
- Daily: Use a wire brush or air gun to clear welding slag and iron filings from the tabletop, and keep the holes clean
- Periodic: Inspect the fixture for wear and check that leg bolts are tight on a monthly basis; the nitrided surface requires no additional anti-rust treatment
- Long-term storage: Plug the holes with dust caps and cover the tabletop with a waterproof tarp to prevent prolonged exposure to moisture
