Product Description
Universal D28 Modular Welding Table Fit All Standard D28 Clamps
Universal D28 Modular Welding Table with standard 100×100mm D28 hole grid, fully compatible with all brand standard D28 clamps, locating angles and lock pins. 5-sided machining design supports 3D flexible fixturing for all heavy fabrication jobs. Nitrided HT300 cast iron/ Q355 steel surface with high flatness tolerance, heavy load capacity up to 2 tons, reusable modular accessories cut custom fixture cost dramatically. Custom table sizes, adjustable legs and mobile wheel stands available.
Tabletop Structure Details
5-Sided 3D Hole Design
The top surface and all four vertical sides (front, back, left, and right) feature a standard 100×100mm D28 grid hole pattern—distinguishing it from cheap 2D welding tables that only have holes on the top surface:
- Allows for fixture mounting from all six directions (top/bottom, left/right, front/back)
- Eliminates clamping blind spots for multi-layer setups, 3D frameworks, and irregularly shaped tubular components
- Enables seamless expansion into extra-large workstations by locking side holes together directly with D28 connecting pins
Standard Hole System Specifications
- Hole Diameter: Φ28mm (tolerance +0.06 to +0.15mm); compatible with all global brands of D28 locking pins and clamps
- Grid Center-to-Center Spacing: 100mm ±0.05mm
- Tabletop Thickness: 23-25mm; Standard Vertical Side Height: 200mm
- Precision-finished smooth hole walls ensure fixture pins insert without snagging or play, providing a wobble-free, secure clamp
Scale Markings
Etched millimeter rulers and X-Y coordinate markings along the table edges eliminate the need for tape measures, enabling rapid positioning and consistent dimensions for batch welding.

Operational Performance
Load Bearing & Stability Performance
The cast iron 3D welding table features a standard static load capacity of 2 tons per square meter and an ultimate instantaneous load of 5 tons, while the alloy steel version supports an ultimate load of 10 tons.
Cast iron comes with natural vibration damping performance. It prevents workpiece shifting caused by vibration during welding arcs, thus lowering dimensional errors and rework rates.
The nitrided tabletop delivers excellent high-temperature resistance, resisting indentation and deformation under short-term splashing weld spatter.
Safety Detailed Design
- All edges and corners of the 3D welding tabletop are processed with rounded chamfers to avoid scratches on operators and workpieces
- Rubber dust plugs are supplied for positioning holes to block iron filings and moisture, preventing corrosion inside idle holes
- The entire 3D welding table is equipotential grounding compatible, which efficiently conducts welding static electricity away to avoid wandering welding arcs
- The thickened base has smooth welded seams without sharp edges, and reinforcing ribs inside the support stand prevent the table from tipping over
Nitrided Layer Characteristics
High-Temperature and Weld Spatter Resistance
The nitrided layer withstands temperatures exceeding 600°C; brief contact with molten weld spatter causes no melting or adhesion, allowing the spatter to be easily knocked off. In contrast, spatter adheres firmly to standard painted or black-oxide surfaces, and cleaning it often scratches the base material.
Rust and Moisture Resistance
The nitriding process creates a dense iron-nitride layer that seals out moisture, cutting fluids, and workshop vapors. This eliminates the need for daily anti-rust oil application in humid southern workshops or coastal facilities, and prevents rusting even during prolonged outdoor storage at temporary workstations.
Low Friction and Wear Resistance
Fixture bases and locking pins operate with minimal sliding resistance during repeated insertion and removal. Even after 100,000 cycles, the hole walls show no significant wear, preventing issues such as excessive clearance or instability during clamping.
No Interference with Welding Conductivity
The nitrided layer is thin and highly conductive, ensuring the welding circuit remains uninterrupted—unlike platforms coated with insulating hard materials.
Common Questions Answered
Can I use D28 fixtures from other brands?
They are fully compatible. The system features a globally standardized 100×100mm grid and Φ28mm bore pattern; it accommodates various German and domestic D28 clamping elements and locating pins without fitment issues—there is no brand lock-in.
Will the holes enlarge under long-term heavy loads?
The nitrided layer is extremely hard; the holes will not enlarge even after tens of thousands of assembly/disassembly cycles under standard clamping forces. Damage to the hole walls occurs only from violent impacts with a heavy sledgehammer.
How do I choose between the steel and cast iron versions?
Cast Iron (HT300): Offers high precision, vibration damping, and rust resistance; the preferred choice for batch precision welding.
Steel (Q355): Offers higher ultimate load capacity and impact resistance; suitable for welding heavy, thick plates and large components for construction machinery.
Steel (Q355): Offers higher ultimate load capacity and impact resistance; suitable for welding heavy, thick plates and large components for construction machinery.
Can it be used with robotic welding systems?
It is fully compatible. The welding table can be paired with a hydraulic lifting base and a welding positioner to form a fully automated welding workstation; it includes designated reference points to facilitate repeatable positioning for robots.
