20th International Forgemasters Meeting - IFM 2017

New AUT (automatic ultrasonic testing) system having capacity to inspect rotor forging of 300 metric ton was developed and successfully deployed to forged rotor manufacturing process. Mock-up test result and product examination experience using new AUT system shows that the system has detectability and sizing accuracy meeting industrial standards; The system can detect 1.6mm FBH (flat bottomed hole). Comparison of sizing result for real defect detected during product examination with manual examination technique shows good agreement. The system is being used as primary examination technique replacing manual technique to enhance the integrity of final ultrasonic examination result of products.
