يرتدون لوحة الصلب: Manufacturing and Processing Technology of Weld Overlay Wear Plate
Clad steel plate (also called weld overlay plate or hardfaced wear plate) is a composite material produced by depositing a wear-resistant alloy layer onto a steel base plate. Its performance depends not only on material composition but also on a precise and controlled manufacturing process.
Compared with ordinary steel plate production, clad steel plate requires multiple metallurgical and welding steps to achieve a stable wear-resistant surface.
1. تحضير المواد الخام
| مادة | وظيفة |
|---|---|
| لوحة الصلب الأساسية | Provides strength and structural support |
| Welding alloy wire/powder | Forms wear-resistant overlay layer |
| Flux or shielding gas | Protects weld quality during deposition |
2. Surface Cleaning and Pre-Treatment
قبل اللحام, the base plate must be thoroughly cleaned:
- قم بإزالة الزيت, الصدأ, and surface impurities
- Ensure clean bonding surface
- Improve metallurgical fusion quality
Proper pre-treatment is essential to avoid delamination and defects.
3. Preheating Process
The base plate is often preheated before overlay welding:
- Reduces thermal stress
- Prevents cracking in hardfacing layer
- يحسن قوة الترابط
Preheating temperature depends on steel grade and overlay system.
4. عملية لحام التراكب
This is the core manufacturing step of clad steel plate.
| Process Type | صفات |
|---|---|
| اللحام بالقوس المفتوح | Common, فعالة من حيث التكلفة, high deposition rate |
| اللحام بالقوس المغمور (رأى) | Stable quality, suitable for large plates |
| منطقة التجارة التفضيلية (Plasma transferred arc) | دقة عالية, excellent carbide control |
| الكسوة بالليزر | High-end process, تخفيف منخفض, أداء عالي |
The wear-resistant layer is built by multiple welding passes to reach the required thickness.
5. Multi-Layer Deposition Control
- Each layer must be precisely controlled in thickness
- Cooling is required between passes
- Carbide distribution must remain uniform
This step determines final hardness and wear resistance.
6. Cooling and Stress Relief
بعد اللحام, controlled cooling is required:
- Prevents thermal deformation
- Reduces internal residual stress
- Improves structural stability
7. Straightening and Finishing
Because welding introduces deformation, finishing processes are required:
- Mechanical straightening
- Surface grinding (if required)
- Dimensional correction
8. القطع والتصنيع
Clad steel plates are often processed into final shapes:
- قطع البلازما
- Waterjet cutting (preferred for precision)
- القطع بالليزر (thin plates)
Special care is needed due to the high hardness of the overlay layer.
9. فحص الجودة
| Test Item | غاية |
|---|---|
| Hardness test | Verify wear resistance level |
| Bonding strength test | Ensure metallurgical fusion quality |
| قياس السماكة | Check overlay uniformity |
| Surface inspection | Detect cracks or defects |
