Modular D16 Welding Table with 16mm Diameter Holes an 50mm Grid for Clamping
The Modular D16 Welding Table with 16mm Diameter Holes and 50mm Grid for Clamping is a core flexible fixture platform for modern welding and assembly workshops. Precision-laid 50mm grid and 16mm locating holes ensure accurate multi-point clamping for small and medium-size workpieces.
Customers can select Q355 welded steel or HT300 cast iron material, with optional five-sided 3D CNC machining and nitrided surface treatment. All blanks are processed by stress-relief to maintain stable flatness year after year.
Thanks to its modular feature, several tables can be connected to build larger working platforms and work with full-range D16 standard accessories. It is extensively applied in cabinet welding, thin-wall sheet metal fabrication, mechanical prototype testing and automated robot welding cells.

- Individual welding tables can be seamlessly joined—using bolts to lock the side positioning holes—to form extra-large work surfaces (e.g., 2000×3000 mm, 2400×4800 mm, etc.)
- After joining, the cumulative error of the hole pattern is controlled within ±0.1 mm, allowing a standard D16 fixture set to be used across the joined surfaces
- Alignment pins must be used during assembly to ensure hole alignment between the tables; relying solely on the bolts to force the connection is not permitted
- Chassis and cabinet welding: Ideal for thin-walled, multi-bend sheet metal; the 50mm dense grid allows for the placement of stops and clamps at multiple points to prevent welding deformation. In contrast, the 100mm grid spacing of the D28 system offers too few positioning points, making it difficult to find suitable clamping locations for thin-walled parts.
- Small-diameter tube frames and aluminum profile racks: The 50mm grid enables precise, short-distance positioning for these smaller components.
- Robotic welding workstations: The compact D16 welding table aligns well with robot operating ranges; multiple fixture sets can be quickly swapped to facilitate flexible production.
- Prototype development: Accommodates frequent design changes without the need for custom welding jigs; reliance on standard fixture combinations significantly reduces tooling development costs.
Proven by global fabricators and welding workshops, our Modular D16 Welding Table with 16mm Diameter Holes and 50mm Grid for Clamping is manufactured under strict quality inspection before export. Every unit is tested for flatness, perpendicularity and grid tolerance.
