D28 28mm Hole 3D Weld Table for Heavy Steel Structure Welding
The D28 28mm Hole 3D Welding Table is perfectly suited for welding operations involving thick steel plates, large steel frames, heavy-duty supports, and connectors. It retains the flexibility of a 3D welding table, offering advantages such as eliminating the need for custom fixtures, quick clamping, and multi-directional welding. At the same time, it meets the stringent requirements of heavy steel structure welding regarding load capacity, fixture stability, and resistance to thermal deformation. It is a key piece of equipment for reducing costs, improving efficiency, and ensuring welding accuracy in heavy steel structure manufacturing.

Core advantages
- Flexible Positioning, Reduced Tooling Costs: Eliminates the need for custom welding fixtures for different heavy steel structures. A single set of D28 series heavy-duty accessories can be used for positioning and clamping multiple workpieces, reducing the design and manufacturing costs of specialized tooling and adapting to the "multi-variety, medium-batch" production model of heavy industry enterprises.
- Fast Clamping, Improved Welding Efficiency: Heavy-duty fixtures are directly installed onto the 28mm hole system with bolts, eliminating the need for drilling or welding. Workpiece clamping/unclamping is completed using only a torque wrench. Clamping time per workpiece is reduced by more than 80% compared to traditional cast iron platforms, significantly improving the welding efficiency of heavy steel structures.
- Multi-directional Welding, Adaptable to Complex Processes: The 3D hole system layout covers the table surface and sides (for some models), enabling horizontal, vertical, and multi-angle welding of workpieces without repeated flipping. This meets the operational needs of heavy steel structures requiring "multiple weld seams and multi-directional welding," reducing the number of workpiece lifting operations.
- Modular Expansion, Adaptable to Extra-Large Workpieces: Standardized splicing positioning holes and connecting bolts are reserved around the table. A single unit can be used independently, or multiple units can be spliced horizontally/vertically (e.g., two 3000×2000mm units can be combined into a 6000×2000mm platform) to temporarily accommodate the welding of extra-large steel structures without purchasing oversized dedicated welding platforms.
- High Durability, Reduced Maintenance Costs: Steel table surface + plasma nitriding treatment provides resistance to slag, burning, and corrosion. Slag can be easily removed after cooling without grinding. The hole system only requires wiping with anti-rust oil every 1-6 months, requiring no complex maintenance, which is ideal for heavy industry workshops without dedicated equipment maintenance personnel.
Key performance parameters
- Load-bearing capacity: The tabletop can uniformly bear a load of ≥1000 kg/m², with a localized concentrated load capacity of ≥500 kg. It can support thick steel plates/steel components weighing over 800 kg each. There is no tabletop sagging or bracket shaking under full load;
- Flatness accuracy: The overall tabletop flatness is ≤0.04 mm/m, and the accuracy degradation after long-term high-frequency welding is ≤0.01 mm/year. This prevents gaps from appearing in heavy steel plate splicing due to uneven surfaces, ensuring the flatness of the welded steel structure;
- Deformation resistance: Under full load conditions, the overall deflection is ≤0.08 mm/m. There is no permanent deformation of the tabletop during high-current welding (≤600A) or when heavy workpieces are struck for correction, eliminating the need for frequent leveling;
- Temperature resistance and impact resistance: It can withstand long-term localized high temperatures from welding arcs ≤700℃, and short-term instantaneous high temperatures ≤1000℃, without the nitrided layer of the tabletop peeling off. It can withstand the impact load during the lifting and placement of heavy workpieces without tabletop cracking or chipping.
FAQ
Q: Which welding processes and workpieces are compatible?
A: Compatible with manual welding, MIG/MAG welding, TIG welding, submerged arc welding, etc. It can handle steel plates ≥20mm thick, heavy steel structures/frames, construction machinery parts, and wind power connectors, and is suitable for high-current welding up to ≤600A.
Q: Is it compatible with standard D28 accessories?
A: Yes, it is fully compatible with global D28 standard heavy-duty accessories (F-clamps, locating pins, hydraulic clamps, etc.). It can also be adapted to D16 light-duty accessories via adapter kits, without brand limitations.
Q: Is a professional team required for installation?
A: No, it features a modular design. Two people can complete the assembly in 40 minutes using a torque wrench. The legs have ±30mm leveling feet, and a standard spirit level is sufficient for leveling.
Q: What is the accuracy of multiple units when joined together?
A: Standard features include connecting locating pins and high-strength bolts. After joining, the hole alignment tolerance is ≤±0.05mm, the flatness difference is ≤0.03mm/m, and there are no steps at the joints.
Q: What is the warranty period?
A: The tabletop accuracy is warranted for 1 year, the overall equipment is warranted for 2 years, and the D28 heavy-duty accessories are warranted for 1 year. Lifetime technical support is provided.
