薄壁金属与非金属环形粘接件粘接质量超声检测方法研究
|
摘要
为了解决薄壁金属与非金属环形粘接件粘接质量的常规无损检测方法缺陷定位、定量准确性不高的问题,本文采用超声C扫描成像检测和接触式超声脉冲回波法,通过对环形粘接件人工缺陷对比试块、粘接产品件的检测,以及人工缺陷对比试块的解剖,对薄壁金属与非金属环形粘接件的粘接质量进行了研究.结果表明采用超声C扫描成像检测方法能检出大面积的脱粘缺陷和气孔缺陷,而接触式超声脉冲回波法无法区分粘接界面的缺陷信号,粘接缺陷无法被检出.因此超声C扫描成像检测方法对环形粘接件粘接质量具有良好的检测适用性和可靠性,是评价薄壁金属与非金属环形粘接件粘接质量有效的无损检测方法.
Defects localization and quantification were not accuracy of thin-walled metal and non-metal annular specimen adhesive quality with conventional NDT methods; The article used ultrasonic C-scan imaging detection technology and ultrasonic pulse-echo contact method to study on adhesive quality of thin-walled metal and nonmetal annular specimen,Through artificial defects reference block was tested and dissected,and adhesive products were tested,The results show that ultrasonic C-scan imaging detection technology can detect large area debond defects and porosity defects,and ultrasonic pulse-echo contact method can not distinguish adhesive interface defects signal,adhesive defects are not detected; So ultrasonic C-scan imaging detection technology have good applicability and reliability of annular adhesive specimen adhesive quality,It is effective NDT method to evaluate thin-walled metal and non-metal annular specimen adhesive quality.
