Supporting Structural Components

Adjustable heavy-duty support legs: Multi-level height adjustment to accommodate uneven workshop floors, with fine-tuning for leveling.
Swivel casters with brakes: 4 heavy-duty casters allow the entire platform to be moved; locking mechanisms ensure stability during operation.
Complete set of D28 modular standard fixtures (optional): Quick-locking pins, right-angle positioning blocks, extension supports, V-blocks, horizontal clamps, cantilever clamps, and angle adjusters.
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
Steel structure fabrication: Equipment frames, curtain wall steel structures, large-scale enclosures, and warehouse racking
Robotic automated welding lines: Large 4×8 meter worktables supporting synchronized multi-robot operations
Sheet metal & stainless steel processing: Large equipment housings and pressure vessel supports
Assembly welding of precision equipment, construction machinery, and rail transit components

Don't waste money on disposable custom welding jigs. Our Precision Machined D28 Welding Fixture Table 4x8 greatly reduces your tooling cost and improves welding precision.
