D28 Modular 3D Nitrided Heavy‑Duty Metal Welding Positioning Work Table

This D28 welding table is a heavy‑duty modular 3D positioning platform built for modern metal fabrication workshops. The tabletop adopts high‑strength Q355 steel with full nitrided surface treatment, equipped with standard D28 hole system at 100mm grid spacing. All matching fixtures are fully interchangeable, allowing users to assemble custom clamping layouts for diverse workpieces. It effectively cuts fixture preparation time and guarantees stable dimensional accuracy for batch welding jobs.

• High rigidity Q355 steel structure effectively resists deformation under heavy‑load welding conditions
• Professional nitrided surface prevents welding spatter adhesion and extends service life
• Full five‑sided hole design supports multi‑direction clamping for complex 3D workpiece positioning
• All fixtures are fully interchangeable, greatly reducing repeated fixture manufacturing cost
• Strict CNC machining ensures stable flatness and consistent hole tolerance for assembly precision
• Flexible dimension customization is supported to fit different workshop production requirements

• Automotive component fabrication: Position chassis parts, brackets and frame assemblies for welding and splicing work
• Machinery frame manufacturing: Fix thick steel structural frames during assembly and welding procedures
• Metal custom fabrication: Serve small‑batch custom welding of special‑shaped metal parts for job‑shop workshops
• New‑energy equipment production: Complete precise welding of equipment brackets and metal housing components
• Heavy hardware processing: Handle medium‑size heavy metal workpieces with reliable heavy‑load capacity
• Welding skill training: Act as standard modular jig platform for vocational welding training courses
