Anti Spatter D16 Nitrided Welding Table Easy Surface Cleaning

The Anti Spatter D16 Nitrided Welding Table is a reliable, flexible welding base for precision metalwork. Its integral plasma nitriding finish produces a low-wettability surface that resists weld spatter sticking and simplifies daily cleanup. Standard D16 Φ16mm H7 holes on a 50mm grid work seamlessly with all D16 modular clamps and locking pins. Available in 2D or full five-sided 3D structure, the table maintains stable flatness for both manual welding and robotic welding stations, lowering your shop's maintenance workload.

• Low weld spatter adhesion makes cleaning effortless; no need for daily application of anti-spatter agents.
• The nitrided layer is formed through diffusion-based surface hardening of the base material — it will not peel or flake, ensuring a significantly longer service life.
• Resistant to rust, workshop humidity, and corrosion from welding fumes.
• The modular fixture system is highly versatile, allowing for rapid tooling changes — ideal for small-batch, high-variety production.

• Process temperature: 520–580°C (low-temperature nitriding).
• Case depth: 0.3–0.5 mm.
• Surface hardness: HV 550–900; an ultra-high-hardness version (HV 870) is available upon request (requires 42CrMo mold steel as the substrate; Q355 steel is typically limited to a maximum hardness of approximately HV 750).
• Metallurgical structure: A dense, non-porous surface layer consisting of ε+γ' nitrides. This is not a surface coating, but a modification of the steel itself through diffusion.
• Deformation control: Due to the low-temperature process, thermal deformation is minimal. Components can undergo CNC precision machining prior to nitriding, with a flatness loss of ≤0.02 mm/m.
• Appearance: Matte, dark charcoal-gray, non-reflective finish. Unlike paint, it will not blister, crack, or peel off in flakes.
• Heat resistance: Can withstand temperatures up to 600°C for short periods; the surface is not immediately damaged by contact with molten welding spatter. However, prolonged exposure to high-temperature heat will cause ablation of the nitrided layer.

Once welding spatter has cooled, remove residue using a flat scraper — a copper scraper is preferred, as it is less likely to scratch the nitrided layer — followed by a wire brush and compressed air. The use of an angle grinder for large-area surface grinding is discouraged, as each instance of grinding removes a portion of the nitrided layer.

Yes, they can be used, though nitrided tables do not require frequent application. A light coating can further reduce spatter adhesion; however, any residual oily film may compromise positioning accuracy, so their use should be minimized in automated workstations.

• Do not subject any single point on the welding table to a high-current electric arc for an extended period.
• Do not strike the edges of the table with a hammer or other heavy objects.
• Do not perform cutting operations directly on the table surface (plasma or flame cutting will burn through the nitrided layer, creating permanent pits).
• Do not perform build-up welding (surfacing) on the table surface.

With proper use, the wear-resistant and anti-spatter properties of the nitrided layer can be maintained for 5–8 years. Frequent grinding or exposure to intense heat will shorten the service life.
