Product Overview
3D Steel Welding Table With Positioning Fixture is a modular 3D steel welding workbench designed for high-precision, multi-angle welding and assembly. It adopts the D28 standard positioning system and is suitable for complex spatial positioning needs.
Model: D28 (28mm standard positioning hole system)
Table size: 2000mm (length) × 1000mm (width) × 200mm (height)
Type: 3D modular welding system (supports X/Y/Z three-dimensional space adjustment)
Material: High-strength steel table (anti-deformation, high temperature resistant)
Matching: Positioning Fixture
Main features
(1) 3D modular design
D28 standard hole system (28mm diameter positioning hole, usually 50mm×50mm spacing)
The workpiece position can be freely adjusted in three directions of X/Y/Z to meet complex welding requirements
Extendable columns, angle adjustment blocks, and rotating tables to achieve multi-angle welding
(2) High load-bearing capacity & high stability
The table thickness is 200mm, providing ultra-high rigidity and anti-deformation ability
Suitable for heavy welding (such as engineering machinery and large structural parts)
Flatness ≤0.1mm/m² to ensure welding accuracy
(3) Matching positioning fixture
Including quick fixture, positioning pin, V-block, etc.
Supports universal adjustment to adapt to different workpiece shapes
(4) Advantages of steel structure
Lighter than cast iron while maintaining high strength
Resistant to high temperature and impact, suitable for high-load welding environment
| Aspect |
Cast Iron |
Q355 (Structural Steel) |
| Material Category |
Iron-carbon alloy with high carbon content (2-4%), produced by casting. |
Low-alloy high-strength structural steel (GB/T 1591-2018), produced by rolling/forging. |
| Common Types |
Gray Iron, Ductile Iron. |
Replaces the old grade Q345. |
| Key Composition |
High carbon (2-4%), high silicon (1-3%), low manganese (0.1-1%). |
Low carbon (≤0.24%), low silicon (≤0.55%), manganese (1.0-1.6%), with microalloys (Nb, V, Ti). |
| Mechanical Properties |
- Tensile Strength: 120-400 MPa (low) |
- Tensile Strength: ≥355 MPa (actual: 470-630 MPa) |
| - Brittle, low toughness |
- High toughness, impact resistance |
| - High hardness (HB 150-300) |
- Moderate hardness (HB 130-180) |
| - Poor weldability. |
- Excellent weldability. |
| Manufacturing Process |
Casting (molten metal poured into molds). Ideal for complex shapes. |
Hot/cold rolling, forging. Easy to cut, weld, and machine. |
| Applications |
Engine blocks, machine tool bases, pipes, cookware (e.g., cast iron pans). |
Structural frameworks (buildings, bridges), ships, pressure vessels, machinery. |
| Advantages |
Cost-effective, wear-resistant, good vibration damping. |
High strength-to-weight ratio, ductile, suitable for dynamic loads. |
| Limitations |
Brittle, difficult to machine post-casting. |
Requires corrosion protection in harsh environments. |
