Computerized ultrasonic tube testing systems with special reference to the installation in tube mills for nuclear tubing of fuel fabrication facilities

During the last years testing systems for high quality tubes had to offer more and more possibilities except flaw detection and dimensional measurement. These additional facilities which are required by the tube manufacturers on one hand and the tube customers on the other hand can be summarized in the slogan statistics. This article discusses the possibilities of a modern tube testing system in connection with digital ''on line'' data processing in using two typical examples which are standard configurations of NUKEM rotating head systems: 1. Systems qualification and monitoring by usiing the so-called ''control card technique''. 2. Production monitoring by statistical methods
