Modular D28 Welding Platform Supports Robotic Automatic Welding Operation
This modular D28 welding platform is a professional industrial grade 3D flexible welding workbench specially optimized for manual welding and robotic automatic welding scenarios. Adopting international standard D28 hole system and high strength cast steel body, the product undergoes strict stress relief annealing and integral nitriding treatment. It features ultra high flatness, strong structural stability and excellent thermal deformation resistance. The fully modular hole layout allows free combination and quick replacement of various fixtures, which can effectively adapt to diverse workpiece processing demands. Designed for modern intelligent welding workshops, it perfectly matches robotic welding stations, realizes precise repeated positioning, and greatly improves the automation level and production efficiency of metal fabrication work.
Core Features
-
Purpose-Built for 3D Modular Positioning
The D28 table is specifically designed for three-dimensional modular workpiece setup. Its grid-based hole system allows fixtures to be mounted on any position, enabling precise clamping of complex shapes and angles that traditional flat tables cannot handle.
-
Nitrided Surface for Durability and Easy Maintenance
The nitrided tabletop resists welding spatter and corrosion effectively, maintaining stable flatness over years of heavy daily use. Weld spatter does not adhere to the hardened surface, making cleanup quick and reducing long-term maintenance costs.
-
Five-Side Fully CNC Machined for Uniform Precision
All five working surfaces are precision CNC machined to ensure consistent accuracy across the entire table. This allows simultaneous fixturing on the top and side surfaces, enabling true 3D positioning for complex assemblies and multi-sided welding jobs.
-
Full Range of Interchangeable Fixtures
Over 100 compatible accessories are available, including locking pins, clamps, angle stops, rotary positioners, V-blocks, and extension arms. All components are fully interchangeable across D28 tables, so you can reconfigure your setup in minutes for different projects.
-
Heavy-Duty Reinforced Frame for Large Loads
The robust steel frame with reinforced underside ribs supports substantial weight, with a standard load capacity of 5 tons and a frame load capacity of up to 10 tons per square meter. This makes the table suitable for both light sheet metal work and heavy structural fabrication.
-
Reduces Setup Time and Eliminates Custom Jig Costs
By replacing project-specific custom jigs with a reusable modular system, the D28 flexible welding table cuts setup time by up to 60 percent and eliminates ongoing custom fixture expenses. One table serves hundreds of different workpiece configurations, delivering rapid return on investment.

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.
