Nitrided Rust Proof Cast Iron 3D Welding Table

Nitrided Rust-Proof Cast Iron 3D Welding Table is a cast iron welding platform based on flexible positioning technology using a hole system. By applying gas nitriding treatment to the table surface, a dense iron nitride protective layer is formed on the cast iron surface, achieving rust prevention without the need for additional painting. This process also significantly improves surface hardness and wear resistance, addressing the industry pain points of traditional welding tables such as susceptibility to rust, rapid surface wear, and accuracy degradation.

• Long-lasting rust protection, maintenance-free

  The nitrided layer formed by nitriding is a chemically bonded protective layer that does not peel off or oxidize. In humid, dusty welding workshops or during long-distance ocean transportation, it can achieve 5-8 years of service without significant corrosion, eliminating the need for regular painting and maintenance, thus reducing operating costs.

• Ultra-high wear resistance, lasting precision

  The hardness of the nitrided surface is 3-5 times that of ordinary hardened surfaces, effectively resisting welding spatter, friction, and impact from tooling and fixtures. After long-term use, the hole walls show no wear and the surface remains scratch-free, maintaining precision far superior to traditional welding tables.

• Flexible adaptation, efficient operation

  The φ28mm standard hole system is compatible with mainstream flexible tooling accessories worldwide (locating pins, quick clamps, square blocks, angle irons, etc.), supporting rapid switching between multiple workstations and welding of various workpieces, significantly improving the efficiency of small-batch and customized production.

• Stable and reliable, anti-deformation

  The HT300 cast iron base material undergoes double treatment of artificial aging and natural aging to completely eliminate internal stress; the 25mm thickened table design effectively resists welding thermal stress and the pressure of heavy workpieces, preventing table sagging and deformation.

• High-precision welding scenarios: such as welding of precision mechanical parts, rail transit connectors, and aerospace components;
• High-humidity/corrosive environments: such as welding of marine engineering equipment, port machinery, and chemical equipment;
• Heavy-duty workpiece assembly: such as assembly of engineering machinery cabs, large steel structures, and mining equipment housings;
• Export-oriented production needs: suitable for use as supporting equipment for export, meeting the high requirements of overseas customers for equipment durability and precision.
