High Precision Nitrided Surface D28 Modular Welding Table

High Precision D28 Modular Welding Table overview

High Precision Nitrided Surface D28 Modular Welding Table is a heavy-duty 3D modular fixturing solution for modern metal fabrication. Adopting D28 Φ28mm hole system with 100 mm grid pitch, the tabletop undergoes full five-sided nitriding treatment for outstanding wear-resistance and anti-spatter performance. With strict CNC machining and artificial stress-relief, it maintains long-term flatness and positioning accuracy. Compatible with global D28 clamping accessories, it supports quick setup, multi-table splicing and robotic welding applications. Available in Q355 steel and HT300 cast iron to satisfy different workshop working conditions.

Main Features

Modular welding table features illustration

Modular Flexible Tooling: No need for customized special fixtures; standardized fixture components can be freely combined. Only the fixture needs to be changed when changing products, significantly reducing tooling preparation time; compatible with mainstream international D28 fixture accessories.
Five-Sided 3D Clamping: Standard holes on the top surface and four sides allow for multi-angle positioning and welding of workpieces from the sides and elevations, suitable for frame and rack assembly welding.
Splicing and Expansion: Multiple welding stations can be spliced together using positioning pins and connecting blocks to handle oversized workpieces.
Matching Adjustable Support Legs: Adjustable height legs and optional movable legs with casters are available.
Artificial Aging Stress Relief: Eliminates internal material stress, preventing deformation of flatness over long-term use—a key process missing in low-priced, inferior workbenches.

Delivery Information

Certifications: CE, ISO9001, meeting EU market requirements; SGS/BV third-party testing reports available.
Trade Terms: Supports EXW/FOB/CIF/DAP/DDP; sea and rail transport; large sizes can be repackaged to reduce sea freight costs.
Delivery Time: Standard sizes 15-20 days; custom sizes 20-25 days.
Warranty: Standard 12-month warranty; extended warranty negotiable; warranty only covers material and processing defects, excluding damage caused by impacts or grinding that damages the nitrided layer.
Customization Options: Non-standard dimensions, laser engraving of customer logo, special hardness nitriding, 2D single-sided welding table, base with robot interface.

Potential Fault Checklist

Fixture insertion/removal jamming: Check for metal filings inside the hole; verify the hole's H7 tolerance; misalignment of the hole grid after splicing requires readjustment of the splicing locking pins.
Stubborn weld slag adhering to the worktable: The nitriding layer has been damaged by grinding; continue large-area grinding is prohibited; localized nitriding can be repaired.
Dimensional deviation of the workpiece after welding: Recheck the flatness of the worktable; check for loose support feet; confirm whether the ground has settled.
Locating pin wobbling: Wear on the inner wall of the hole, generally due to insufficient nitriding layer or prolonged overload use.
