All accessories are compatible with the full range of D28 welding tables, enabling 3D clamping in any direction (X, Y, and Z axes).
Core Product Advantages
Flexible, Universal Tooling
Significantly cuts costs associated with custom fixtures. A single 4×8 welding table can handle dozens of different weldments; no need for dedicated welding jigs for each product, with changeovers requiring only 10 minutes to reconfigure clamps.
Five-Sided 3D Clamping Capability
With holes on the top surface and all four side walls, the system enables multi-angle positioning—including vertical, inclined, and suspended setups—allowing for comprehensive, all-angle welding of complex chassis and steel structures.
High-Precision Consistency
Positioning tolerances are in the micron range, ensuring minimal dimensional variation within batches; ideal for mass-producing steel structures, trailers, and construction machinery components, as well as for use in robotic welding stations.
Extra-Large 4×8 Work Surface
The massive 1.2m × 2.4m table accommodates heavy-duty workpieces such as truck chassis, construction machinery arms, large stainless steel frames, and agricultural machinery structures.
Wear-Resistant & Durable
Made from cast iron or nitrided alloy steel, the table resists high-temperature weld spatter and impacts, maintaining precision with minimal degradation over more than a decade of standard industrial use.
Mainstream Application Industries
Heavy-duty vehicles: Welding of truck frames, trailer chassis, construction machinery undercarriages, and agricultural machinery frames
