Laser Cladding Phương Đông
Why is rotor repair necessary?
The rotor is the central rotating component of a hydro generator, operating under heavy load and in harsh conditions. Over time, it often experiences:
- Surface wear at bearing or journal areas
- Cracks, pitting, or scratches due to friction and temperature
- Dimensional deviations affecting dynamic balance
- Chemical corrosion or damage during maintenance
If not properly addressed, these issues can significantly reduce power generation efficiency, cause vibration, compromise stability, or even lead to complete system shutdown.
Laser Cladding – The optimal solution for rotor restoration
Laser Cladding is an advanced surface engineering technology that uses a high-power laser beam to fuse a wear-resistant alloy onto the base material. It is particularly suitable for rotor repair thanks to its outstanding advantages:
- High precision: Targets only the damaged areas without affecting surroundings
- Low heat input: Prevents distortion or structural damage to the base metal
- Enhanced surface performance: Excellent wear, heat, and stress resistance
- Restores original dimensions with minimal tolerance (< 0.01mm)
- Time- and cost-saving alternative to full replacement
