Laser cladding troubleshooting
Problems with laser cladding?
Problem | Cause | Solution |
Deposit peels off | 1. Poor preparation of the surface (oxidized or dirty surface) 2. Too low preheating temperature 3. Too fast cladding speed 4. Wrong parameters / Bad bonding |
Clean the surface well Increase preheat Increase power |
Cracks |
1. Overheating / too high welding power, too high dilution |
Reduce welding power |
Porosity |
1. Poor preparation of the surface |
Clean the surface well |
Clogging |
1. Incorrect particle size |
Reduce fines content Adjust and control the cooling water temperature |
