1. Material: Q355 steel
• Characteristics:
Low - alloy high - strength structural steel (domestic standard, equivalent to European standard S355 or American standard ASTM A572 Grade 50).
High tensile strength (470-630 MPa) and yield strength (≥355 MPa), with strong load - bearing capacity.
Good weldability and toughness, suitable for heavy - duty welding/assembly scenarios.
Contains alloying elements such as manganese (Mn) and silicon (Si), with better corrosion resistance than ordinary carbon steel.
2. Nitriding surface treatment
• Process: In a nitrogen - rich environment at 500-600 °C, nitrogen atoms are infiltrated into the steel surface to form a hardened layer.
• Advantages:
Ultra - high hardness: The surface hardness reaches 800-1200 HV (about 2 - 3 times that of ordinary steel), resistant to wear and scratches.
Fatigue resistance: Extends the service life of the platform under repeated clamping and impact.
Corrosion resistance: The nitriding layer can resist welding spatter and oxidation in a humid environment.
Low deformation: The heat treatment process hardly causes dimensional changes, maintaining the flatness of the platform.
3. 3D modular design
• Standardized hole array: Usually, 100×100mm or 50×50mm grid holes are used, compatible with various fixtures (such as quick - clamps, dowel pins).
• Expandability: Multiple platforms can be spliced to adapt to the processing of large workpieces.
• Flexibility: Supports three - dimensional space positioning, suitable for welding complex structural parts.
4. Core performance characteristics
• High precision: The flatness can reach ±0.1mm/m², ensuring the positioning accuracy of workpieces.
• High - temperature resistance: The nitriding layer can withstand the welding high temperature for a short time (avoid direct long - term burning).
• Load - bearing capacity: Typical load is 2-5 tons/m² (specifically depending on the thickness of the steel plate, usually 20-40mm).

Nitrided 3D Q355 Steel Welding Table Modular Welding Platforms
Typical application scenarios
• Welding of automotive/aerospace structural components.
• Assembly of heavy components in construction machinery.
• Automated welding robot workstations.
Advantages compared with ordinary welding platforms
• Longer lifespan: The wear resistance of nitrided treatment is more than 3 times higher than that of untreated or galvanized steel plates.
• Higher efficiency: The modular hole array enables rapid switching of tooling, reducing adjustment time.
• Cost-effectiveness: Although the initial investment is relatively high, the long-term maintenance cost is lower.
Maintenance points
• Cleaning: Regularly remove welding slag with a wire brush to avoid accumulation.
• Protection: Spray anti-spatter agent (such as PTFE coating) to protect the surface.
• Prohibited operations: Avoid direct grinding on the platform surface to prevent damage to the nitrided layer.
