Modular Fixture Nitrided Welding Table is a high-precision, high-strength welding and assembly platform, mainly used in machinery manufacturing, automotive parts welding, metal structural parts assembly and other fields. Its core features are modular design and nitriding heat treatment process, providing excellent wear resistance, deformation resistance and repeatability.
Main parameters
Model: Modular fixture nitriding welding table
Dimensions: 1200mm (length) × 1200mm (width) × 100mm (height)
Table thickness: Usually 100mm refers to the table thickness to ensure high rigidity
Hole system standard: Commonly D28 (28mm series, hole spacing 50/100mm) or D16 (16mm series, hole spacing 50mm)
Material: High-strength alloy steel (such as S355J2 or similar materials)
Surface treatment: Nitrided heat treatment
Core features
(1) Modular design (Modular Fixture System)
Standard hole layout: The table is covered with precision-machined standard threaded holes (such as M12 or M16), which is convenient for installing various fixtures, locating pins and quick clamping devices.
Scalability: Can be combined with other modular fixtures to meet the welding needs of workpieces of different sizes and shapes.
Quick changeover: Suitable for multi-variety and small batch production, reducing tooling adjustment time.
(2) Nitrided Surface
Ultra-high hardness: The surface hardness can reach HV900-1100 (ordinary steel plate is only HV200-300), which greatly improves wear resistance.
Corrosion resistance: The nitride layer can prevent welding spatter from adhering and rusting.
Deformation resistance: After heat treatment, the thermal stability is better and it is not easy to deform after long-term use.
(3) High precision and stability
Flatness: ≤0.05mm/m² (precision grade), ensuring welding assembly accuracy.
Repeat positioning accuracy: ±0.02mm, suitable for high-precision welding and inspection.
Rigid structure: 100mm thick table + reinforcement rib design, with a load-bearing capacity of 5-10 tons/m².
(4) Multifunctional application
Welding: Suitable for MIG/MAG, TIG, laser welding and other processes.
Assembly: Can be used for positioning and assembly of mechanical parts.
Inspection: As a reference platform for coordinate measuring machines (CMMs).
Supporting fixtures and accessories
The workbench can be equipped with a variety of modular fixtures, such as:
Toggle Clamps: for quick fixation of workpieces
Dowel Pins: to ensure precise alignment
Angle Plates: for complex angle welding
Magnetic Fixtures: suitable for thin plate welding
