D16 3D Welding Table with Q355 Steel and Nitriding Finish

Upgrade your metal fabrication workshop with our D16 3D welding table, a five-sided modular fixture platform crafted from premium Q355 high-strength steel and treated with full plasma nitriding. Designed for precision small-batch welding, its dense 50×50mm Φ16 hole grid enables flexible 3D multi-angle clamping, completely replacing costly custom single-use jigs.
The exclusive nitriding hardened surface solves long-standing workshop troubles including stubborn welding spatter, surface abrasion and rust corrosion, delivering stable machining accuracy and ultra-low maintenance for years of heavy-duty welding work. Perfect for precision sheet metal, robot welding stations and prototype manufacturing.

- Flatness: ≤0.1mm/1000mm; maintains precision stability under long-term heavy loads and high-temperature welding.
- Perpendicularity: 0.1mm/200mm between the sidewall and the table surface; ensures precision for vertical tooling setups.
- Machining Method: Integral 5-sided CNC milling; precision machining of all holes in a single operation to eliminate stress-induced deformation.
- Aging Treatment: Integral annealing of the steel plate for stress relief; prevents warping or deformation during subsequent use.

Solution: D16 welding table featuring a dense 50×50mm grid and 3D multi-angle clamping capabilities; modular, universal fixtures enable rapid tooling setup (10 minutes) for prototyping, eliminating mold-making costs.
Solution: Gas-nitrided hardened surface prevents spatter adhesion; spatter falls off easily with a light tap, reducing grinding labor by 60%.
Solution: High-strength Q355 base material combined with stress-relief annealing ensures lasting flatness stability and a service life three times longer than standard Q235 platforms.
Solution: Composite nitriding and oxidation treatment provides 96-hour neutral salt spray corrosion resistance with no risk of coating delamination.
Solution: The D16 table's dense 50mm grid offers four times the positioning point density of D28 tables, eliminating clamping blind spots for thin sheets and small, irregularly shaped parts.
