The rotor is a critical component of the Roots blower – a device commonly used in air supply systems for wastewater treatment plants, aquaculture facilities, food processing, cement production, textile, and dyeing industries.
After prolonged operation, the shaft journals of the rotor often experience wear, scratches, or dimensional loss, directly affecting equipment performance and service life.
Laser Cladding technology provides an efficient solution to restore the rotor’s dimensions with high precision, enhanced wear resistance, and minimal thermal distortion.

Advantages of Laser Cladding:
- Accurate dimensional restoration and alignment
- Corrosion- and wear-resistant alloy coatings
- No deformation or heat-affected zones
- More cost-effective than replacing new parts

Laser Cladding Restoration Process:
- Cleaning and inspection of the rotor
- Machining and surface preparation at worn areas
- Laser Cladding with specialized alloy powder
- Post-cladding finishing and machining
- Final inspection for concentricity, dimensions, and hardness

After the Laser Cladding process, the rotor shaft journals are restored to their original specifications and are ready for operation under harsh industrial conditions.
At PHUONG DONG INDUSTRY, we specialize in the restoration of mechanical parts using Laser Cladding technology. We also supply complete Laser Cladding systems and high-performance alloy powders for cladding and thermal spraying applications.
