Abstract:

Ultrasonic array technique for assessing the integrity of the circumferential electron beam weld between the lid and walls of copper canisters is presented in the paper. The results of laboratory verification of the performance of the ultrasonic array system on real canister samples are presented. A method for suppression of grain noise scattered from the internal copper structure based on digital filtering B-scan images is verified in this application.
