Flatness Inspected D28 3D Welding Table For High Precision Heavy Workpieces
Our Flatness Inspected D28 3D Welding Table is specially engineered for high-precision and heavy-duty welding workpieces. Unlike ordinary single-sided 2D welding platforms, this 5-sided perforated 3D workbench delivers omnidirectional clamping in X, Y and Z axes, eliminating positioning dead angles for complex frames, thick-plate structures and heavy machinery parts.
Every table is scanned by laser flatness tester across the entire working surface to guarantee consistent benchmark accuracy. Built with heavy-load reinforced structure and plasma nitrided surface treatment, it resists welding spatter, abrasion and thermal deformation, serving as a stable, long-lasting base for batch precision welding.

Core Advantages of the 3D Structure
Five-Sided Full-Hole 3D Clamping
The top surface and four side walls of the welding table are uniformly distributed with D28 standard holes, allowing the workpiece to be fixed from any direction—up, down, left, right, front, or rear. Circular pipes, irregular box structures, and three-dimensional trusses can all be quickly positioned without the need for custom fixtures.
Modular Flexible Production
Equipped with a full set of standard fixtures (positioning angle ruler, telescopic clamping device, lifting support, V-block, quick pin), one workbench can switch between dozens of products, reducing tooling preparation time by 70% and saving significant costs on custom fixtures.
Heavy-Duty Anti-Deformation Structure
The interior of the box is densely reinforced with ribs, and the base is equipped with a thickened support plate, ensuring that the surface does not sag even when supporting heavy workpieces weighing several tons for extended periods, and it resists permanent deformation under high-temperature thermal stress during welding.

Frequently Asked Questions
Q: Can you provide flatness inspection certificates?
Yes. Every single welding table is fully scanned by laser flatness detector before shipment. Digital and paper inspection reports can be sent together with your order.
Q: Will the table sink or deform under heavy load?
No. Our tables adopt 25mm thick Q355B steel plate with dense internal ribs and double stress relief treatment. It maintains flatness under rated maximum load without permanent deformation.
Q: Is it possible to connect multiple tables together?
Absolutely. With matched D28 connecting plates, several tables can be spliced to form an extra-large working area, while keeping unified flat benchmark.
Q: Do you offer complete fixture kits together with the 3D welding table?
We provide full-series D28 standard accessories as optional add-ons. You can select single tools or a full fixture package at checkout to save procurement time.
If you are looking for a long-term, high-stability precision welding benchmark for heavy workpieces, our flatness inspected D28 3D welding table will be your reliable production partner.
