Flexible D28 Modular 3D Welding Positioning Work Table System
The Flexible D28 Modular 3D Welding Positioning Work Table System is a professional multi-dimensional industrial welding workstation designed for modern precision metal fabrication. Built with high-strength structural steel and integrated integral machining technology, this D28 welding table adopts a standard 50mm grid hole layout to support full directional fixture assembly and multi-angle workpiece positioning.
Different from traditional fixed welding platforms, this modular system allows free combination, quick disassembly and flexible rearrangement of various tooling accessories. It effectively solves common industrial pain points such as single processing mode, long setup time and poor repeated positioning accuracy. Suitable for diversified welding production, prototype debugging and customized batch processing, this table delivers stable structural rigidity, excellent flatness and reliable working performance, helping manufacturing enterprises optimize production processes and improve overall welding quality and efficiency.
Core Features
Full 3D Multi-Side Flexible Clamping Function
Five-side perforated design enables clamping on top and four vertical sides. Operators can fix workpieces at horizontal, vertical or inclined angles to handle irregular heavy components such as machinery frames and pipeline structures without blind positioning zones.
Ultra Stable Precision for Batch Welding
Strict CNC milling and uniform hole machining keep consistent positioning tolerance for long-term repeated use. All finished workpieces maintain unified dimensional standard which effectively reduces reject rate in mass welding production.
High Wear Resistant Nitrided Table Surface
Integral high-temperature nitriding forms a dense hard protective layer on the whole tabletop. It strongly resists welding spatter adhesion, scratches and oxidation corrosion, extending table service life under daily high-frequency workshop operation.
Universal Modular Accessory Compatibility
Standard D28 hole grid matches all global mainstream modular fixture parts. Users can freely assemble and adjust clamps and supports for different workpieces without manufacturing exclusive custom jigs for every new project.
Heavy Load Bearing Deformation Resistant Structure
Thickened Q355 steel plate and internal reinforced rib framework deliver outstanding weight capacity. The table surface stays flat without bending even under long-time heavy workpiece pressure and impact load during welding.
Greatly Improved Workshop Production Efficiency
Rapid fixture combination and fast workpiece clamping cut setup time significantly. Less manual adjustment lowers labor input and shortens production cycle, helping factories raise daily output and control overall manufacturing expenses.

Product Applications
This D28 modular 3D welding positioning system covers a wide range of heavy metal processing industries. It is widely used for engineering machinery frame welding, rail transit component assembly, energy pipeline fabrication, automobile chassis processing, steel structure manufacturing and heavy equipment part repair. It works well for prototype trial, small batch custom production and formal mass production lines, compatible with manual welding stations, robot welding cells and workpiece inspection procedures.
Frequently Asked Questions
What's the difference between D16 and D28 welding tables?
D28 (28mm holes) is designed for heavy industrial work - thicker plates, larger workpieces, and higher clamping forces. D16 (16mm holes) is for lighter, precision assembly work. D28 accessories are NOT compatible with D16 tables and vice versa.
What does "3D five-sided" mean?
It means the table has precision-machined D28 holes on the top surface AND all four vertical sides. You can mount clamps and fixtures horizontally, vertically, or at angles - enabling true 3D fixturing for complex weldments.
How flat is the table, and how is it measured?
Our D28 tables guarantee ±0.1mm flatness per square meter. Each table is measured with a precision electronic level and laser tracker across multiple grid points before shipment. A flatness inspection report can be provided upon request.
What is nitriding, and why is it important?
Nitriding is a heat treatment that infuses nitrogen into the steel surface, creating a hard, wear-resistant layer (≥HV600). It protects against welding spatter, scratches, and corrosion - extending table life by 3-5 times compared to untreated steel.
Can I use my existing D28 accessories from other brands?
Yes, as long as they use the standard 28mm pin diameter and 100mm grid spacing. Our D28 system follows industry-standard dimensions, so most third-party D28 fixturing components will be compatible.
Do you offer custom sizes and configurations?
Absolutely. Send us your specifications for a custom quote.
How is the table shipped? Does it need assembly?
Standard models ship fully assembled - just unbox and place on your shop floor. Larger tables may have legs packed separately for transport safety, but assembly takes about 30 minutes with basic tools. Full instructions are included.
What's the warranty on the D28 welding table?
We offer a 1-year warranty against manufacturing defects. Normal wear from welding spatter and everyday use is not covered, but the nitrided surface is designed to last for years of heavy industrial use.
