D28 D16 3D Flexible Welding Platform Special Welding Workbench Nitrided 2000*3000 is a high - end tooling equipment that combines aperture hole system and nitriding surface strengthening technology. It is specifically designed for complex welding, assembly, and inspection processes. Its core value lies in meeting the needs of modern manufacturing for flexible and efficient production through its modular, high - precision, and durable characteristics.
Nitriding Treatment Process
• Process Type: Gas nitriding (low cost, uniform diffusion layer) or ion nitriding (high precision, small deformation).
• Characteristics of the Diffusion Layer:
Surface Hardness: ≥800HV (Vickers hardness, more than 3 times that of ordinary steel).
Diffusion Layer Depth: 0.2 - 0.3mm, balancing wear resistance and base material toughness.
Temperature Resistance: Can withstand a high temperature of 600ºC in the short term, and the long - term operating temperature ≤400ºC.
• Advantages:
Resistant to welding spatter adhesion, reducing cleaning costs.
Resistant to corrosion from coolant and grease, suitable for humid or chemical environments.
Reduces the friction coefficient and extends the service life of fixture locating pins.

1. Three - dimensional flexible expansion
• Vertical expansion: Column modules can be installed to form a three - dimensional tooling system, supporting multi - face synchronous processing of workpieces.
• Horizontal expansion: Multiple units can be spliced to form a continuous working area (customized docking accuracy of ±0.1mm is required).
• Functional modularization: Compatible with rotary tables, flipping mechanisms, and automated fixtures, suitable for robot welding units.
2. Long - term benefits of the nitrided layer
• Reduced maintenance cost: Traditional platforms need to be repaired regularly due to the wear of the hole walls. Nitriding treatment can extend the maintenance cycle to 2 - 3 years.
• Precision durability: The nitrided layer resists mechanical wear, ensuring that the hole position tolerance changes ≤ ±0.01mm within 5 years.
• Environmental adaptability: Suitable for harsh working conditions such as high humidity (e.g., shipbuilding) and high dust (e.g., construction machinery welding).
We have many different product for your recommend!
1. Heavy Equipment Manufacturing
• Application case: Welding of wind turbine towers - Use the D28 hole system to fix the cylinder body, and install a laser tracker through the D16 hole to calibrate the weld trajectory.
• Advantages: The high-rigidity tabletop resists welding deformation, and the nitrided layer can withstand long-term arc thermal radiation.
2. Aerospace Precision Assembly
• Application case: Assembly of aircraft wing ribs - Fine-tune the positioning pins through the D16 hole system to achieve an assembly accuracy of ±0.1mm for composite materials.
• Advantages: No magnetic interference (Q355B steel + nitrided layer), compatible with operations on sensitive materials such as carbon fiber.
3. Multi-variety and Small-batch Production
• Application case: Customized production of construction machinery - On the same platform, by changing the fixtures, the welding of the excavator boom and the loader frame can be quickly switched.
• Advantages: Modular tooling reduces the changeover time by 70%, supporting agile manufacturing.
