Repair Methods Overview
1. Welding
- Low cost
- High deformation risk
2. Thermal Spraying
- Fast process
- Weak bonding
3. Laser Cladding (Recommended)
Laser cladding provides:
- Metallurgical bonding
- High precision
- Long service life
Performance Comparison
| Method | Bonding | Precision | Lifespan |
|---|---|---|---|
| Welding | Medium | Low | Low |
| Spraying | Low | Medium | Medium |
| Laser Cladding | High | High | High |
