Perforated Welding Fixture Table
Product Overview
The perforated welding fixture table is a modular grid clamping fixture system for metal fabrication. With regularly perforated datum holes, it serves as a universal fixture base for positioning, tacking, welding, assembly and dimensional checking.
This fixture table is available in 2D single-sided and 5-sided 3D construction. Two standard hole systems are optional: D16 (φ16mm, 50×50mm grid) and D28 (φ28mm,100×100mm grid). Surface options: raw steel or nitrided finish.
All modular clamping components including clamps, locators, stops, angle brackets and support blocks are fully compatible, forming a flexible fixture solution without custom dedicated jigs.

Core Advantages
-
Precision Datum Grid
The perforated welding fixture table features CNC-machined hole grid with tight tolerances. Standard datum holes enable flexible mounting of clamps, locating pins and stops anywhere on the table to fulfill various positioning requirements.
-
Flexible Modular Clamping
This perforated welding fixture table is fully compatible with standard modular accessories. Fixture layout can be quickly adjusted for different workpieces, cutting the high cost of custom one-off jigs.
-
Excellent Stability
The perforated welding fixture table body is stress-relieved to minimize thermal deformation during welding. Optional nitrided surface delivers excellent wear resistance and anti-spatter property for easy slag cleaning.
-
Consistent Repeat Positioning
With uniform standard hole grid, the perforated welding fixture table ensures stable repeat positioning accuracy. It serves as an ideal fixture base for robotic welding lines and mass production.
Application Fields
