This nitrided surface treatment 3D welding fixture table is a high - end modular tooling platform designed specifically for the manufacturing industry. It is suitable for precision manufacturing processes such as welding, assembly, and inspection. It adopts the D28 hole system (standard holes with a 28mm pitch), and the tabletop size is 1500×3000mm. The table has undergone nitrided surface treatment to improve wear resistance, corrosion resistance, and service life.
Core Features
1. Nitriding Treatment
Enhanced Hardness: Through the nitriding process (gas nitriding or ion nitriding), the surface hardness can reach HV900 - 1200, far exceeding that of ordinary welding tables.
Wear and Corrosion Resistance: The nitrided layer can effectively prevent welding spatter, scratches, and chemical corrosion, extending the service life.
Reduced Adhesion: The surface is smoother, reducing the adhesion of metal debris or welding slag, making it easier to clean and maintain.
2. 3D Modular System
D28 Standard Hole System: The tabletop is covered with positioning holes of φ28mm, with a pitch of 28mm (compliant with European standards DIN/ISO), compatible with various fixtures and dowel pins.
Three - dimensional Adjustability: The fixture position can be adjusted arbitrarily in the X, Y, and Z directions to meet the welding requirements of complex workpieces.
High - precision Positioning: The hole position tolerance is small (±0.05mm), ensuring repeat positioning accuracy, suitable for high - precision welding and assembly.
3. Heavy - duty Industrial - grade Structure
High - strength Materials: Usually made of high - quality alloy steel (such as S355JR), with a tabletop thickness of ≥30mm and strong load - bearing capacity (up to 5 - 10 tons/m²).
Anti - deformation Design: The internal rib - stiffened structure ensures no deformation during long - term use, suitable for welding large workpieces.
Grounding Interface: Some models are equipped with welding grounding terminals to prevent current interference and improve welding quality.
4. Multi - functional Applications
Welding: Suitable for MIG/MAG, TIG, laser welding, and other processes.
Assembly: Can be used for precision assembly in industries such as machinery manufacturing, auto parts, and aerospace.
Inspection: Can be used as a reference platform for coordinate measuring machines (CMM) or laser inspection.

How to use a 3D fixture table for better and quicker woking?
1.Consider the characteristics of the workpiece: select the appropriate platform model according to the size, shape and weight of the workpiece. For example, D16 series platforms are often used for sheet metal and small steel structures, while D28 series platforms are often used for large steel structures and heavy machinery industry.
2.Selecting the Platform Structure: Flexible welding platforms are categorized into three main series based on their structural types: hole system combination fixtures, slot system combination fixtures, and combination punches. The slot system combination fixtures are available in three sizes: 16mm, 12mm, and 8mm, corresponding to large, medium, and small combination fixtures, respectively. Choose the appropriate structural type based on your specific requirements.
3.Select the right material and manufacturing process: Choose a platform produced by a regular manufacturer to ensure that the material meets national standards (such as cast iron HT200-300) and that the manufacturing process is excellent. Pay attention to checking the hardness of the working surface of the platform, which should be HB170-240 and has been properly heat-treated to ensure its stability and durability.
4.Consider the platform's scalability and adaptability: Evaluate whether the platform can be extended by adding support components (such as U-shaped square boxes, L-shaped square boxes, or angle iron supports) to accommodate larger workpieces. Assess whether the platform can be easily assembled and combined according to the shape and size of the workpiece.
