斜探頭的磨損對(duì)管材超聲波探傷結(jié)果的影響
Effect on Ultrasonic Detection Result of Tube Flaw by Wear of Oblique Probe
-
摘要: 在超聲波探傷過程中,斜探頭會(huì)受到磨損,由此會(huì)使其入射點(diǎn)、折射角發(fā)生改變,影響超聲波探傷的準(zhǔn)確性。介紹了超聲波斜探頭的選擇,入射點(diǎn)和折射角的測(cè)定方法及在超聲波探傷過程中使用探頭應(yīng)注意的問題。Abstract: During the operation of the ultrasonic detector the oblique probe is subject to wear,which consequently leads to the change of the incident point and the refraction angle and thus to produce some negative influence on the detection accuracy.Such aspects as the selection of the ultrasonic probe,the measuring method for the incident point and the refraction angle,and some key points for the probe during the operation of the ultrasonic detector,are all described.
