| Abstract: | a TR and ultrasonic focusing wheel probe is designed for some special engineering testing item. Ultrasonic TR thickness measurement and detection can be carried out without coupling medium. With the testing system and the probe set on a control machine car,pipe wall thickness can be detected periodically by a method dry couple. Aligned and marginal testing for steel plate's quality and the thickness testing of corroded pipe wall can be accomplished by dry couple method. The processing method of detection si... |
