Meet our Precision flat D28 3D welding fixture table for weld jigs — your flexible alternative to expensive fixed weld jigs. Featuring a 100mm pitch 28mm hole grid on top and four vertical sides, this 3D welding table enables accurate X/Y/Z positioning for complex metal assemblies. Controlled flatness, stress-relieved structure and optional nitrided surface keep your positioning consistent batch after batch. You can reuse all D28 standard clamps, pins and blocks to reconfigure fixtures in minutes — ideal for mixed orders, prototype work and robotic welding stations.
- Rough machining and stress relief: Rough machining is followed by artificial aging (stress-relief annealing) to release internal stresses in the plates, preventing the tabletop from warping or losing flatness over time.
- Precision CNC milling: Precision CNC milling of the top, bottom, and all four sides (X, Y, and Z axes).
- Drilling and reaming to H7 tolerance: 28mm-diameter holes with a positional tolerance of ±0.03mm, ensuring smooth insertion and removal of locking pins with zero-clearance positioning.
- Optional gas nitriding: This is not paint. Nitrogen is diffused into the metal surface to create a 0.3–0.5mm hardened layer (hardness HV450–900), providing resistance to weld spatter adhesion, wear, and rust. The inner walls of the holes are also hardened, ensuring that frequent, long-term use of locking pins does not enlarge the holes, thereby maintaining positioning accuracy for many years. (Welding tables without nitriding are only suitable for low-frequency prototyping workshops.)
- Laser-engraved grid lines and scales: X/Y-axis markings eliminate the need for manual measuring and scribing, allowing for rapid coordinate location.

- Load capacity: Static load capacity per standard leg is 700–1000 kg. The entire tabletop supports a uniform static load of 3–5 tons for standard models, while heavy-duty reinforced versions can reach 10 tons. Dynamic load capacity for welding operations (accounting for vibration and impact) is reduced by half.
- Leg options: Fixed legs, adjustable leveling feet (standard), mobile versions with casters, and hydraulic lifting legs for adjusting the workbench height.
- Modular configuration: Multiple D28 welding tables can be joined together using specialized locking connectors, allowing for an infinitely extendable surface — ideal for fabricating long vehicle frames, container girders, or large-scale steel structures. Once connected, the system maintains a continuous reference plane with perfectly aligned hole patterns.
- Construction machinery, agricultural machinery frames, trailer chassis, and semi-trailer frameworks
- Pipelines, pressure vessels, and steel structural frameworks
- Automated robotic welding stations, and integrated welding & inspection stations
- Sheet metal frames, equipment frames, frameworks for new energy applications, and prototypes for construction machinery
- Doors and windows, railings and fences, amusement ride structures, and RV/caravan frameworks
- Flexible tooling: A single platform accommodates dozens of different workpieces, significantly reducing the costs associated with custom jigs.
- Multi-sided 3D positioning: Provides stable clamping for angled, vertical, and complex, irregularly shaped components.
- Nitrided surface finish: Resists weld spatter, ensuring that when spatter is knocked off, it leaves no pits or scratches on the reference surfaces.
- Modular and expandable: Easily scale up production capacity; existing components can be reused, maximizing asset utility.
- Consistent precision: Ensures dimensional uniformity across batches, reducing the need for rework during subsequent assembly.
A: Sure. Custom dimensions, table thickness, special hole layout and customized nitriding hardness are all acceptable. Tell us your drawing or workpiece size.
A: We support EXW, FOB, CIF, DAP and DDP. Our sales team will calculate the freight and delivery plan based on your destination port.
A: Standard size tables in stock can be shipped quickly. Custom size, cast iron or special hardness orders take longer production time. We will confirm the exact lead time on your PI.
A: Both options are available. You can buy only the tabletop, or a full set including locking pins, clamps, angle blocks and other fixturing accessories.
Our Precision flat D28 3D welding fixture table for weld jigs delivers stable precision and flexible fixturing for heavy fabrication and robotic welding projects. Send us your drawing or workpiece details, and we will work out a suitable solution for your workshop.
