Hydropower Turbine Seal Insert Ring Restoration by Laser Cladding

The Wear Problem of Turbine Shaft Insert Ring in Hydropower Plants

The turbine shaft insert ring is a critical component in hydropower turbine shafts. After long-term operation, it is often subjected to wear, scratches, or corrosion due to continuous friction and harsh working environments. This leads to leakage, reduced efficiency, and poses a significant risk of serious system failures.

Instead of a full replacement, Laser Cladding offers a precise, cost-effective, and durable solution for restoring the damaged surface.

Why Choose Laser Cladding for Turbine Shaft Insert Ring Restoration?

  • Low heat input – no distortion of base material
  • High-performance wear-resistant alloy coating
  • Strong metallurgical bonding – long service life
  • High accuracy with CNC-controlled process
  • Cost savings up to 50–70% compared to replacement

Laser Cladding Repair Process for Turbine Shaft Insert Rings

  1. Inspect and assess the condition of the worn bearing
  2. Clean and prepare the surface
  3. Mount the part on a CNC rotary table
  4. Perform laser cladding with selected alloy powder
  5. Finish machining (turning/grinding)
  6. Inspect coating thickness, adhesion, hardness, and surface finish

Practical Applications in Hydropower Plants

Phuong Dong’s laser cladding technology has been successfully applied in many hydropower projects, including:

  • Nam Luc Hydropower Plant
  • Song Lo Hydropower Plant
  • Ba Thuoc Hydropower Plant
  • And various other hydropower facilities across Vietnam
