High Hardness Nitrided D28 Hole Grid Welding Table

High Hardness Nitrided D28 Hole Grid Welding Table
The High Hardness Nitrided D28 Hole Grid Welding Table is a heavy-duty, high-precision 3D modular welding platform designed for professional steel fabrication, robotic welding, and heavy structure manufacturing. Different from ordinary painted welding tables, this model adopts vacuum plasma nitriding heat treatment to achieve extreme surface hardness, anti-welding spatter, rust-proof performance, and long-term stable flatness. It is the standard high-end workstation for European and American heavy industry factories.
All tables adopt a 100mm standard D28 grid system, fully compatible with global standard D28 fixtures, clamps, positioning pins, and support accessories. 5-sided working design allows 3D multi-angle clamping, greatly improving welding efficiency and precision for custom and mass production.

Industrial Advantages
  • Superior wear and impact resistance: Resists dents and scratches during workpiece hoisting and repeated fixture clamping, maintaining surface flatness over the long term.
  • Weld spatter resistance and easy cleaning: A dense nitrided layer prevents molten spatter from adhering; residue falls off with a light tap, significantly reducing time spent on grinding and maintenance.
  • Rust and corrosion resistance: Resists corrosion from moisture, welding fumes, and salt spray; remains rust-free in humid workshops or outdoor environments without the need for frequent oiling.
  • High-temperature dimensional stability: The surface does not soften under localized welding temperatures of 800-1500°C; the welding table maintains its flatness and dimensional accuracy during long-term use.
Comprehensive Flexible Tooling System
The D28 grid system is compatible with a full range of standardized accessories, allowing a single 3D welding table to replace dozens of specialized welding fixtures:
D28 Welding Table Tooling System D28 Grid System Accessories
  • Positioning: 28mm cylindrical pins, diamond-shaped error-proofing pins, positioning stops, angle locators
  • Clamping: Quick-action clamps, adjustable support blocks, vertical L-brackets, clamp plate locking bolts
  • Expansion: Tabletop connecting locks, riser supports, mobile support legs with brakes (optional height-adjustable casters)
Pre-treatment Process
The entire unit undergoes shot blasting and sandblasting to remove mill scale, welding slag, and oil, while activating the metal surface; this ensures a uniform nitriding layer and prevents issues such as localized insufficient hardness, discoloration, or rust spots. In contrast, standard painted models undergo only simple grinding and lack this process.

Export Packaging Solutions
  • Tabletop Unit: Reinforced with a solid wood base pallet; fully covered with thick EPE foam; solid wood corner protectors to prevent impact damage; wrapped in waterproof film to guard against rain and salt spray during ocean transit.
  • Accessories and Legs: Packed separately in small solid wood crates; bolts and pins feature plastic sleeves to protect the threads.
  • Logistics Terms: Supports FOB, CIF, DDP, and DDU, including full door-to-door overseas shipping; suitable for clients in Europe, Southeast Asia, Central Asia, South America, and Australia.
  • Packaging Dimensions: A single 2000×1000 tabletop fits into a 20GP container; bulk packing multiple units helps reduce shipping costs.
Purchase Recommendations
  • Select the workbench size according to the maximum workpiece size.
  • Consider future production needs and reserve expansion space.
  • Choose well-known brands to ensure quality and after-sales service.
  • Consider whether additional functions such as rotation and tilting are required.
  • Evaluate the compatibility and expandability of the fixture system.
This welding fixture workbench is especially suitable for medium-large iron product manufacturing enterprises that require high-precision and high-efficiency welding, and can significantly improve welding quality and production efficiency.

High Hardness Nitrided D28 Hole Grid Welding Table is particularly suitable for high-precision welding and assembly operations of medium and large workpieces, and is an ideal process equipment choice for modern manufacturing companies.
