Why Choose the 3D welding tables?
One of the advantages of opting for a 3D welding table is the level of precision it offers. While traditional flat tables may be suitable, for projects intricate welding tasks require precision in every dimension. With a 3D welding table welders have a three workspace that allows them to position their workpieces with accuracy. This not enhances the quality of the welds. Also reduces the need for extensive rework.
Versatility to Suit Projects
Whether you're working on a small scale project or tackling scale industrial applications 3D welding tables prove to be highly versatile. The adjustable fixtures and modular design of these tables can accommodate workpieces of sizes and shapes. This adaptability is crucial in todays diverse welding landscape, where professionals often face a range of projects.
Flexible modularization for rapid reconstruction
Adopting standardized grid hole systems (e.g., D28/D16) and modular components (locating pins, square boxes, support blocks, etc.), it enables quick construction of clamping schemes for different workpieces, reducing the production changeover time from 4-8 hours (traditional) to 15-30 minutes.
High-precision positioning with stability and reliability
The base hole system and plane feature high precision, with a repeat positioning accuracy of up to ±0.05mm, ensuring accurate positioning in the 3D space (X/Y/Z) and reducing welding deformation and misalignment.
Efficient integration for automation compatibility
It can be integrated with robotic welding systems, CAD/CAM software and sensors, supporting automatic path planning and thermal deformation compensation to realize 24/7 continuous production.
Cost optimization for long-term benefits
Reducing the design, manufacturing and maintenance costs of special tooling, standard parts can be reused, and the comprehensive cost decreases significantly with the increase of product batches.

PRODUCT DETAILS
The D28 3D Steel Nitriding Welding Table is a heavy-duty, high-precision industrial welding workbench, engineered for large-scale, heavy-load 3D welding, assembly, and positioning tasks. Constructed with high-strength Q355 steel (or equivalent alloy steel) and treated with professional nitriding technology, it offers superior rigidity, wear resistance, and corrosion resistance, making it ideal for heavy machinery manufacturing, steel structure fabrication, shipbuilding, and other industrial fields requiring high load-bearing and precision positioning.
Core Material & Nitriding Advantage
The table uses high-quality Q355 steel plate as the base material, which has excellent tensile strength and impact resistance. The entire surface undergoes a precision plasma nitriding treatment, forming a dense nitride layer with a surface hardness of HV900-1200—far exceeding ordinary steel tables (HV300-500). This treatment delivers:
Extreme wear resistance: Resists scratches and indentations from heavy workpieces, welding spatter, and frequent tool use.
Strong corrosion resistance: Prevents rust and oxidation in harsh workshop environments with welding fumes, coolants, and humidity.
Non-stick & easy cleaning: The nitrided surface repels welding spatter and debris, simplifying post-operation maintenance.
Long-term stability: The nitride layer bonds tightly to the steel substrate, avoiding peeling or cracking even under thermal cycling (-20°C to 150°C).
Structural Design & 3D Operational Flexibility
D28 Precision Hole System: Features 28mm diameter positioning holes arranged in a 100×100mm grid (±0.05mm tolerance) across the top and 4 side surfaces (5-sided working area). The hole walls are hardened to resist wear from repeated pin insertion, ensuring consistent positioning accuracy for heavy workpieces.
Modular 3D Positioning: The 5-sided design allows multi-directional clamping and expansion, supporting vertical, horizontal, and complex 3D welding operations. It can be combined with D16 auxiliary holes (50×50mm grid) for dual-aperture flexibility in fine-tuning and heavy-load positioning.
Reinforced Steel Structure: The tabletop (24-27mm thick) is reinforced with understructure ribs to enhance rigidity and load-bearing capacity, preventing deformation during high-intensity use.
Applications & Accessories
Application Scenarios: Heavy machinery assembly, large steel structure welding, shipbuilding sections, bridge component fabrication, and other heavy-load precision manufacturing tasks.
Compatible Accessories: U-shaped/L-shaped support blocks, positioning squares, V-shaped locators, quick-locking pins, retractable clamps, height adjusters, and lifting rings—enabling quick setup and flexible clamping for diverse workpieces.
Why Choose D28 3D Steel Nitriding Welding Table?
Heavy-Load Precision: D28 hole system and 100mm grid spacing excel at positioning large/heavy workpieces, outperforming smaller D16 tables in load capacity.
Durable Steel Construction: High-strength steel with nitriding treatment offers better impact resistance than cast iron, ideal for high-vibration industrial environments.
Modular Flexibility: 5-sided working surfaces and compatible accessories support multi-station operation and customized setups, reducing production changeover time.
