Product Description
3D Modular D28 Welding Table with 28mm Diameter Reference Holes
Cut your fixture costs and boost production repeatability with our 3D Modular D28 Welding Table with 28mm Diameter Reference Holes. This five-sided modular welding platform adopts the D28 standard 28 mm reference hole and 100 mm grid layout, enabling X-Y-Z multi-direction clamping for complex frames and heavy components. Thanks to stress-relieved substrate and full nitrided finish, the table sustains tight flatness and perpendicularity tolerances under long-time heavy-load welding. Mix and match D28 locating pins, angle boxes, quick clamps and support blocks to adapt to new workpieces within minutes. Multiple dimension options and supporting leg assemblies are offered for manual welding lines as well as automated robot welding stations.

Structural Characteristics
- 5-Sided 3D Structure: D28 reference holes are arranged not only on the top surface but also on all four sides, allowing workpieces to be mounted vertically, laterally, or at an angle for 3D positioning—ideal for welding complex frames, chassis, and housings.
- CNC Machining & Artificial Stress-Relief Aging: Eliminates internal machining stresses to ensure long-term dimensional stability; the surface features a 100mm grid scale for quick positioning without the need for repeated measurements.
- Nitrided Surface: Resists weld spatter and burn-in, offers high wear resistance, minimizes spatter adhesion, and extends the welding table's service life.
- Modular Compatibility: Fully compatible with all D28 standard accessories (locating pins, square boxes, angle squares, support blocks, quick clamps) for flexible combinations; multiple tables can be joined to create an extra-large welding platform.
- Support Legs: Equipped with adjustable feet for leveling the table surface; optional mobile casters are available, and some configurations support integration with robotic bases.
Identifying Inferior Products
- Partial Nitriding: Nitriding only the top surface while leaving the inner walls of the holes untreated causes hole walls to quickly wear down, leading to loose positioning; standard practice requires nitriding the entire inner surface of all holes.
- Skipping Artificial Aging: The new surface appears precise, but warps after a period of use without proper stress relief.
- Paint Substitution: Using paint instead of nitriding reduces cost but results in treatment failure quickly under welding conditions.
Comprehensive Tolerance System
A complete welding table system requires more than just flatness; the overall geometric tolerances determine repeatability.
| Specification | Tolerance |
|---|---|
| Positioning hole diameter | Φ28 D10 (+0.065 to +0.149 mm) |
| Hole grid spacing | 100 mm; ±0.05 mm between adjacent holes; ±0.10 mm across large diagonal spans |
| Work surface flatness | 0.1 mm/1000 mm; maximum ≤0.3 mm for the entire plate (based on a 2000×1200 mm example) |
| Perpendicularity between side and top surfaces | 0.1 mm/200 mm; poor perpendicularity at the side holes of 3D welding tables causes vertically mounted fixtures to tilt |
| Perpendicularity of hole axis to work surface | ≤0.05 mm; ensures positioning pins insert without tilting |
| Etched grid scale | ±0.2 mm; for reference only—cannot replace positioning pins for actual alignment |
Frequently Asked Questions
What is your warranty policy?
Table body comes with 1-3-year warranty against manufacturing defects. Wearing parts such as locating pins, clamps and bolts are consumables and not covered by warranty. Damage caused by improper operation, arc striking directly on table surface or heavy impact is excluded.
What is your shipping term?
FOB and CIF terms are available. Goods are packed in export-qualified wooden crates / steel frame with pallet. Please advise your destination port for exact freight quotation.
How should I maintain the D28 welding table?
Clear welding spatter and metal chips after work. Use dust plugs for unused reference holes. Clean and apply thin high-temperature grease for locating pins regularly. Do not strike arc directly on working surfaces. Re-check flatness periodically.
What industries or applications is this table suitable for?
Widely used for chassis, frame, cabinet, heavy mechanical structure fabrication, robot welding workstation, metal assembly and checking. Not recommended for ultra-precision metrology measurement.
