D28 Welding Table with Fixture Clamps and Accessories

Stop wasting time and money on custom, single-use welding jigs. Our D28 Welding Table with Fixture Clamps and Accessories is a complete 3D flexible clamping workstation engineered for modern metal fabrication. Built around the widely adopted D28 Φ28mm hole grid (100×100mm) on the tabletop and four side panels, it allows 360° multi-dimensional clamping and alignment for simple and complex welded assemblies. The package includes all essential fixture clamps, positioning pins, angle blocks, V-blocks and supporting hardware ready out of the box. The tabletop undergoes stress relief and precision CNC machining, optional ion nitriding delivers excellent wear and spatter resistance. With high flatness and heavy load capacity, it works perfectly for manual MIG/TIG welding and automated robotic welding stations. All D28 accessories are fully interchangeable with global standard D28 systems.

1. Quick Clamp (Toggle Clamp): Features a red handle for rapid clamping; the most common type, used for vertical workpiece clamping.
2. Screw Clamp: Designed for heavy-duty applications requiring high clamping force; suitable for thick plates or heavy structural components.
3. U-shaped Clamping Blocks & L-shaped Right-Angle Positioning Blocks: Used for 90-degree positioning to ensure the squareness of a frame.
4. Dowel Pins & M16 Bolts: Used to secure components into the D28 holes, serving as a reference for precise positioning.
5. V-shaped Positioning Blocks: Used for positioning cylindrical parts, such as pipes or tubing.

1. Thermal Deformation Control
   The nitrided surface is highly heat-resistant, preventing weld spatter from fusing to the tabletop.
2. Repeat Positioning Accuracy
   When a fixture setup is removed and reinstalled, it maintains a repeat positioning accuracy of ±0.05mm, ensuring consistent results for batch production.
3. No Need for Dedicated Tooling
   In traditional welding, specific jigs and fixtures must be fabricated for each product—and discarded once production of that item ends. With the D28 flexible welding table, components can be disassembled and reconfigured, making it the most cost-effective solution for high-mix, low-volume production.
4. Five-Sided Fixturing Capability (3D Functionality)
   Featuring D28 holes on the top surface and all four side walls, the table allows for vertical, angled, or side-clamped workpiece positioning—ideal for multi-angle welding of enclosures, frames, and complex, non-standard components.

1. Not suitable for sustained, heavy, concentrated point loads, as these can cause localized indentations on the table surface.
2. Do not perform plasma or flame cutting directly on the table surface; high temperatures can damage the nitrided layer and compromise the flatness of the surface. Cutting operations must be carried out on a separate, dedicated cutting platform.
3. Strictly avoid grounding the workpiece by attaching a high-current ground connection to a single point on the table, as this can cause localized arc erosion and pitting. It is recommended to use a large-area copper busbar for grounding.
4. Not suitable for environments with strong acids or alkalis, which can corrode the nitrided layer; the table is intended for use in standard workshop welding environments.
5. Suitable for: Manual MAG/MIG and TIG welding, robotic welding, assembly, inspection/gauging, marking out, and positioning for drilling.

1. Construction Machinery Manufacturers: Welding of thick plates for chassis, buckets, and supports.
2. Automation Integrators: Robotic welding cells and integrated robotic workstations.
3. Steel Structure / Sheet Metal Fabricators: Machine frames, equipment enclosures, and guardrail frameworks.
4. Research Institutions / University Laboratories: Assembly of tooling and development of inspection fixtures.
5. Vehicle Manufacturing: Trailer chassis, RV frames, and forklift components.
6. Mold and Tooling Manufacturers: Prototyping of jigs and fixtures, and reference platforms for inspection and measurement.
