Product Description

47"x 94" 3D Welding Table D28 Nitrided Welding Soldering Station

The 47"×94" 3D Welding Workbench (D28 Nitriding Welding/Brazing Workstation) is a large-scale, high-precision modular welding platform designed specifically for heavy industrial welding, precision assembly, and the positioning of complex workpieces.

The key information is analyzed as follows:
• 47"×94" (approximately 119×239cm): The size of the workbench (width×length), providing an extra-large working area, suitable for large workpieces or multi-station simultaneous operations.
• 3D Welding Table: Supports three-dimensional (X/Y/Z axis) precise positioning, suitable for welding requirements with complex spatial angles.
• D28: It refers to the diameter of the standard positioning holes on the workbench being 28mm (a commonly used industry specification, compatible with most fixture systems).
• Nitrided: The tabletop has undergone a special surface hardening process, significantly improving wear resistance, high-temperature resistance, and rust prevention capabilities.

Product Advantages

1. Ultra-high precision: The nitride tabletop has excellent stability and will not deform after long-term use.

2. Versatility: Compatible with various processes such as welding, brazing, assembly, and inspection.

3. Efficiency improvement: The modular design reduces the workpiece adjustment time by more than 90%.

4. Durability: The nitriding treatment enables the tabletop to have a lifespan of more than 10 years (the lifespan of an ordinary tabletop is about 3 - 5 years).

Core Features

(1) Structural Design
• Heavy-duty Steel Frame: Welded with high-strength alloy steel (such as S355JR), featuring strong overall rigidity and excellent anti-deformation ability.
• Modular Tabletop: Covered with D28mm standard positioning holes (hole pitch is usually 50mm or 100mm), enabling quick installation of fixtures, locating pins, and auxiliary tools.
• Octagonal/Rectangular Options: Some models offer an octagonal edge design for multi-angle operation.
(2) 3D Positioning System
• Three-axis Precision Adjustment:
X/Y Axis: Achieves planar positioning through the tabletop hole system and slides (accuracy up to ±0.05mm/m).
Z Axis: Can be equipped with a height adjustment module or lifting bracket to adapt to workpieces of different thicknesses.
• Angular Positioning: Integrated adjustable angle fixtures (such as universal rotating clamps) support continuous adjustment from 0° to 360°.

(3) Nitrided Tabletop
• Process Advantages:
Surface hardness reaches HV900 - 1100 (far exceeding ordinary quenched steel), and the wear-resistant life is increased by 3 - 5 times.
High temperature resistance up to 600°C, suitable for long-term high-intensity welding operations.
Strong corrosion resistance, adaptable to humid or chemical environments.
• Surface Characteristics:
Precision ground with a flatness of ≤0.03mm/m².
Low friction coefficient for easy workpiece sliding and adjustment.
