Product Description
The D28 3D Welding Table with Hardened and Ground Surface for Accurate Fixture Setups is a professional modular welding platform engineered for precision fixture assembly. Featuring plasma nitrided hardened layer and precision ground flat working surface, the 5-sided D28 hole grid enables 3D multi-angle clamping with full D28 accessory compatibility. High wear, spatter and corrosion resistance ensures long-term stable locating accuracy for batch metal fabrication, robotic welding and heavy structural welding projects. Multiple table sizes, adjustable support legs and splicing kits are available to customize your workshop workstation.
Product Material Comparison
| Comparison Item | Q355 High-Strength Steel Welding Table | HT300 Grey Cast Iron Welding Table |
|---|---|---|
| Thermal Stability | High temperature resistance, resistant to cracking under local open flame; local burn damage can be repaired via surfacing welding and grinding | Minimal thermal deformation, slow precision attenuation during long-term mass production, excellent vibration damping performance |
| Load Bearing | Lighter weight at the same dimension, static load capacity of single table: 5-10 tons | Heavier self-weight, static load capacity: 8-12 tons, ideal for heavy workpieces |
| Repair Performance | Local spatter burn marks can be restored by surfacing welding and grinding | Cast iron cannot be repaired by welding; severe surface damage requires re-grinding only |
| Application Scenarios | Export overseas orders, large frames, mass production for heavy industry | Precision robotic welding, inspection benchmark tables, high-precision small workpieces |
Core Product Functions
- Flexible Modular Tooling: Equipped with D28 standard accessories (locking pins, right-angle positioning blocks, support boxes, quick clamps, and wedge fixtures), eliminating the need for custom molds and allowing for tooling reconfiguration in just 10-30 minutes when switching products.
- Three-Dimensional Positioning: Holes on the top surface and all four sides enable omnidirectional workpiece positioning (up/down, left/right, front/back), preventing misalignment during welding of irregularly shaped frames, racks, and boxes.
- Stable Batch Dimensions: The hardened, precision-ground table exhibits extremely slow accuracy decay over long-term use, ensuring uniform dimensional deviations for each welded part in mass production, and compatibility with robotic automated welding production lines.
- Reduced Correction Processes: Precise positioning and controllable welding deformation significantly reduce post-weld correction, grinding, and shaping time, improving production efficiency.
Countertop Body Specifications
Standard Size Range
Regular Stock Sizes: 1000×1000 / 1200×2400 / 1000×2000 / 1500×3000 / 2000×4000mm; Custom sizes and lengths are available.
Standard Table Thickness: 25mm; Uniform Side Wall Height: 200mm; Positioning holes are machined on 5 sides (top + four sides) for true 3D clamping.
D28 Hole System Precision Parameters
- Hole Diameter: Φ28.10±0.03mm (D10 precision tolerance grade, compatible with all D28 locking pins and M16 clamping bolts)
- Grid: Standard 100×100mm square grid, with diagonal pre-drilled auxiliary positioning holes
- Three layers of closely spaced holes on the side walls, with 50mm hole spacing in the top and bottom rows and 100mm hole depth in the middle
- 35-40mm, countersunk hole with chamfered design to prevent weld slag from getting stuck in the clamping pins and facilitate quick insertion and removal
Daily Usage Guidelines
- Do not strike the welding table surface directly with a sledgehammer to avoid localized stress deformation; place support blocks under heavy workpieces to distribute pressure.
- Do not continuously weld directly above a single hole for extended periods, as weld slag can easily clog the hole; small sacrificial steel plates can be used to protect the welding area.
- For thin-walled stainless steel parts, magnetic clamps should be used preferentially to avoid damaging the workpiece's appearance with mechanical clamps.
FAQ
Q: What's the difference between D16 and D28 3D welding tables?
A: D28 features Φ28 standard holes with stronger load capacity, thicker tabletop and higher impact resistance, suitable for heavy workpieces above 500kg. D16 is a light-duty model for small sheet metal and thin tube fabrication. All our D28 accessories are fully interchangeable without custom jigs.
Q: Can the tabletop resist welding spatter and high heat?
A: Yes. The plasma nitrided hardened layer withstands short-term high temperature from welding sparks without pits or permanent marks. Ordinary untreated tabletops will be burned and deformed quickly within months.
Q: What is your production lead time?
A: Standard in-stock sizes: 15-20 working days. Custom-sized tables: 25-30 working days. Accessory kits can be delivered together with the main table.
Q: What trade terms do you accept?
A: We support FOB, CIF, CFR, DDP and DDU global door-to-door delivery. Main shipment ports: Shanghai, Wuxi, Tianjin.
Q: Can I get samples before bulk order?
A: Small D28 fixture accessories samples are available for testing. Full-size welding tables are large heavy equipment; we provide detailed dimension drawings, production videos and customer workshop case photos for your evaluation.
Our D28 3D Welding Table with Hardened and Ground Surface for Accurate Fixture Setups delivers stable high precision and outstanding durability for all heavy welding projects.
