The Universal D16 Hole System 3D Welding Table is a fully modular, high-precision 5-sided welding fixture platform designed for small and medium welding workshops, sheet metal fabrication, and robot welding stations. Adopting the global standard D16 (Φ16mm / 50×50mm grid), this table is 100% compatible with all standard small welding fixing tools, clamps, pins, and supports without any adapters or custom modifications.
Unlike heavy-duty D28 welding tables for thick steel structures, the D16 hole system features denser grid spacing, allowing ultra-fine positioning for thin sheets, small frames, and precision metal parts. It replaces expensive custom welding jigs with reusable modular tooling, drastically reducing setup time and production costs.
Technical Specifications
All D16 welding tables adopt universal Φ16mm hole / 50×50mm grid standard, fully compatible with all standard small welding jigs and clamps. 5-sided perforated design, ion nitrided anti-spatter surface, high precision and long durability.

Safe Use Guidelines
Do not perform high-temperature surfacing or cutting directly on the tabletop for extended periods; use a heat-resistant backing plate to prevent deformation caused by localized high heat.
Use designated lifting eyes when hoisting the welding table; do not lift from a single point to avoid twisting the tabletop.
Do not strike positioning pins forcefully when clamping workpieces; this prevents the hole walls from expanding and causing a loss of precision.
Before moving a workbench equipped with casters, release workpiece clamps and remove any heavy objects from the tabletop.
The welding machine's ground cable must be connected to the dedicated grounding terminal on the workbench; do not make arbitrary ground connections, as this can cause localized arc damage to the tabletop.
After-sales Warranty Service
1-year comprehensive warranty: Covers the main unit, cast/steel base, and machining accuracy (excluding man-made damage); includes free repairs and parts replacement.
6-month warranty for standard fixtures and locking pins; replacement parts available separately for wear-prone clamping heads.
After-sales response: Email/WhatsApp reply within 2 hours and solution provided within 24 hours for overseas customers.
Value-added services for key accounts: On-site accuracy calibration (1-2 times per year) and guidance on comprehensive equipment cleaning and maintenance.
OEM/ODM customization support: Customer logo branding, custom dimensions, diagonal grid hole patterns, and tailored fixture sets.
