| Abstract: | After a deep study of the configuration and defect feature,a series of specimens with U notch in different angles is designed and manufactured. The emission acoustic fields of multi crystal plates in different refracting angles has been simulated. With the help of the M2M 256×256 Ultrasonic Phased Array facility and software platform Multi2000, the setting of Multi-Salvo is completed. And the client software which based on VC++6.0 has been developed, which can realize the real-time display and data storage of A-scan, and image fitting and real-time display of B-scan for specimen with special configuration. It becomes possible to achieve 100% inspection of Jacket Sections for ITER superconducting cables by the means of rotating the specimen for 90å after each-time inspection. |
