Ultrasonic Feature Imaging System for Testing Bimetal Rotor Clad Layer
نویسندگان
چکیده
An ultrasonic feature scan imaging system used for testing delamination flaw probably existing in the bimetal rotor clad layer was studied and developed. The bimetal rotor with nine column holes can be tested automatically. All the wave train of testing result will be saved in computer for post processing. There are various imaging modes including depth imaging and amplitude imaging, to find delamination flaws accuracy and estimate their size. Imaging experiments for actual work piece was done using the system, and all kinds of feature information were collected. The system has high stability and repeat-ability.
