| 摘 要： | 对不等厚焊缝进行超声波探伤时,由于其厚度不均匀,从超声波探伤仪器上读出的数据不能准确地对焊缝缺陷进行定位。通过对各种不同的不等厚焊缝反复测试,分别对直射波、一次反射波进行分析计算,并完成相关数据转换,保证不等厚焊缝的准确检出。

| Abstract: | During the ultrasonic flaw detection on unequal thickness weld,due to uneven thickness,the ultrasonic testing instrument data read from ultrasonic flaw detection instrument were not accurate for the localization of weld defect. Through kinds of unequal thickness of weld on the different repeated tests,the direct wave and primary reflection tests were analyzed and calculated,and the data conversion were completed,ensured accurate detection on unequal thickness weld. |
