D28 3D Flexible Welding Table, including the production of heavy structures and parts
The D28 3D Flexible Welding Table is an industrial-grade modular precision welding fixture platform. It utilizes the D28 standard hole system (28mm hole diameter) and supports X/Y/Z three-dimensional positioning and rapid clamping. Designed specifically for welding, assembly, and precision inspection of heavy structural components and large parts, it is suitable for heavy manufacturing applications in industries such as construction machinery, wind power, shipbuilding, and steel structures.

- Exceptional Rigidity and Load-Bearing Capacity
Table Structure: Typically made of high-strength alloy steel or high-strength cast iron, with a thickness far exceeding ordinary workbenches, and featuring internal reinforcing ribs. This ensures extremely high stability under heavy loads of several tons to tens of tons, with virtually no deformation.
D28 System Advantages: The large Φ28mm hole diameter and matching large clamps provide powerful locking force and support strength, sufficient to firmly secure large steel plates, profiles, and heavy components.
- Unparalleled Precision and Repeatability
Even for heavy-duty production, precision remains its core value. The table surface is precisely milled and heat-treated, resulting in extremely high flatness. All positioning hole coordinates are precise, and combined with precision clamps, ensure consistent assembly dimensions for large workpieces. Once the clamp positions are programmed or recorded, perfect repeatable production of the same workpiece or series of workpieces can be achieved with minimal error.
- Stress-Free Clamping, Controlling Welding Deformation
For large welded structures, thermal deformation is a major challenge. This system allows for flexible multi-point, multi-directional clamping from optimal angles, avoiding internal stresses caused by forced restraint. Through reasonable support and sequential welding, it can actively control and significantly reduce overall workpiece deformation, reducing subsequent correction work.
- Extremely High Production Efficiency
Rapid Changeover: Switching from one workpiece to another usually only requires adjusting or replacing clamp positions, without replacing the entire tooling. Changeover time can be reduced by more than 80%.
Parallel Operation: Multiple workstations can perform assembly, spot welding, and other operations simultaneously on the same table without interference.
Foundation for Automation: Its high precision and standardized interfaces make it an ideal foundation for integrating robotic welding and automated handling, easily upgrading to an intelligent welding cell.
- Construction Machinery: Welding and assembly of large, complex structural components such as the boom, dipper stick, and frame of excavators and loaders.
- Heavy Vehicles and Rail Transit: Precision assembly of truck chassis, mining truck frames, train car underframes, and bogies.
- Energy Equipment: Welding of large structural components for wind turbine tower flanges and bases, and hydroelectric power equipment.
- Structural Steel: Manufacturing of large bridge nodes, building embedded parts, and special heavy steel beams.
- Shipbuilding and Offshore Engineering: Precision prefabrication of hull sections, deck modules, and offshore platform blocks.
- Pressure Vessels and Boilers: Assembly of circumferential and longitudinal seams of large cylindrical bodies, and precise positioning and welding of nozzles and supports.
- Core Warranty: The entire machine is covered by a 12 to 24-month quality warranty (starting from the date of acceptance of the equipment). During the warranty period, free repair or parts replacement will be provided for malfunctions caused by materials or manufacturing defects.
- Accuracy Warranty: A separate, long-term accuracy guarantee (e.g., 24 months) is provided for the flatness and hole diameter accuracy of the worktable, ensuring its reliability as a measurement reference.
- Clearly Defined Scope: The warranty scope and exclusion clauses (such as man-made damage, improper use, consumable parts, etc.) will be clearly stated in the contract.
