Standard Dimensions
1000×1000 / 1500×1000 / 2000×1000 / 2000×1500 / 3000×2000 / 4000×2000 mm, custom oversized splicing available
Matching Locking Bolt
M16 standard locking bolt, fully interchangeable with global D28 fixture accessories
Key Points Regarding Structure and Fabrication
Artificial aging for stress relief: Stress-relief aging is performed after rough machining to eliminate internal stresses from casting or rolling; this ensures long-term dimensional stability and lasting precision.
CNC 5-sided integrated milling: The top surface and four side walls are precision-machined in a single setup, ensuring perpendicularity between the sides and the top. Holes on the sides allow for lateral and vertical fixture mounting, enabling true 3D clamping (unlike standard 2D welding tables, which only feature holes on the top surface).
Nitrided surface: Rust-resistant and anti-spatter (weld spatter does not easily adhere), reducing the need for grinding and cleaning while extending the table's service life; the process hardens the surface layer without compromising the base material's internal toughness.
Bottom reinforcement ribs: Densely arranged reinforcement ribs on the underside enhance rigidity, ensuring minimal deflection or deformation under heavy loads.
Support system: Comes standard with heavy-duty legs; optional steel frame bases or hydraulic lifting bases are also available to adjust the table height for manual or robotic welding applications.
Core Product Advantages
High-precision, repeatable positioning: Ensures consistent welding dimensions across a batch of workpieces, reduces the need for rework, and meets tight tolerances required for precision metal manufacturing.
Flexible versatility: A single welding table setup accommodates dozens or even hundreds of different products, offering exceptional cost-effectiveness for workshops handling high-mix, low-volume production.
5-sided 3D clamping: Allows for clamping on the top surface as well as all four sides, enabling the secure positioning of workpieces at inclined or vertical angles.
High rigidity and load-bearing capacity: Suitable for welding thick plates and heavy workpieces.
Globally standardized, interchangeable accessories: Compatible with mainstream international D28 tooling components, making it convenient for export-oriented customers to source spare parts.
FAQ
Q: Can I use my existing D28 brand accessories on your welding table?
A: Yes. Our D28 hole system follows international standard dimension. M16 locking bolts, locating pins, angle blocks and clamps from global mainstream D28 suppliers are fully interchangeable.
Q: What is the load capacity of D28 welding fixture table?
A: Single support leg static load: 900‑1000 kg. Whole table static load: 5‑10 tons. Dynamic welding working load is around 2 tons. Please avoid long‑term single‑point overload.
Q: What documents can you provide for export orders?
A: We can offer ISO9001 certificate, CE mechanical‑directive certificate, dimension inspection / measurement protocol. Third‑party witness inspection such as SGS is acceptable before shipment.
Q: What is your warranty term?
A: 12‑month standard warranty against manufacturing defects. Impact damage, arc‑burn marks and consumable spare parts (locking pins, clamps, bolts) are excluded from warranty. Worn holes can be repaired by bushing replacement instead of changing the full tabletop.
Q: What is your lead‑time and packing for export?
A: Standard sizes:10‑15 working days. Custom oversized sizes:20‑30 working days. Export fumigated wooden case packaging.
Q: Can you supply STEP CAD files for robot offline simulation?
A: Yes, CAD STEP files can be provided upon customer request for fixture layout and robotic welding simulation.
