D28 welding table with 28mm holes
,welding fixture table rigid construction
,D28 welding table heavy duty
The D28 Welding Table Featuring 28mm Holes and Rigid Construction is a precision modular 3D welding bench with standard 28mm locating holes and stress-relieved rigid box construction. Built for heavy industrial welding, its five-sided hole layout supports flexible multi-direction clamping, while high-rigidity structure ensures stable flatness under heavy loads. Compatible with full series D28 clamps and locking pins, this 28mm hole welding table speeds up fixture assembly and improves welding accuracy for vehicle, railway and steel structure manufacturing.

- Modular Flexible Fixturing: Eliminates the need for custom-made jigs; utilizes a 28mm hole grid combined with angle blocks, positioning stops, quick-action clamps, and adjustable supports to configure workholding setups for any workpiece in just 10-30 minutes.
- High Precision and Long-Term Stability: Features stress-relief heat treatment and precision CNC milling, with factory-engraved millimeter scales. Maintains flatness even under prolonged welding and heavy loads.
- Wear-Resistant Nitrided Protective Layer: Both steel and cast-iron surfaces undergo nitriding treatment, creating a hardened surface layer of 0.25-0.35mm for resistance to high-temperature weld spatter, rust, and scratches.
- Heavy-Duty Capability for Diverse Applications: The high-rigidity box-type structure supports heavy workpieces weighing several tons, suitable for automotive frames, rail transport components, and construction machinery.
- Low Barrier to Entry: Standardized accessories eliminate the need for professional layout or marking; reduces fixture setup time by 70% and supports flexible production.
Seamless Connection with Aligned Reference Points: Multiple D28 welding tables can be connected in series using extended locating pins; the joints are flush with no steps, hole-spacing references align perfectly across the assembly.
Flexible Configuration Options: Supports linear connections, L-shaped corner configurations, and multi-station grid layouts; a single system handles everything from small individual components to large vehicle frames.
Advantages of Modular Connection: Eliminates the need for custom, massive single-piece tables, making transport, assembly/disassembly, and maintenance easier; units can be separated for individual use.
