    <p>Введение. Задачей квалификационных испытаний является определение реальных возможностей установок НК по выявлению дефектов, расчёт ошибок измерения размеров дефектов.&#13;
Метод. Предыдущий опыт проведения квалификационных испытаний показал, что получить дефекты с заданными параметрами только изменением режимов сварки невозможно. Дефекты были выполнены механическим или электроэрозионным способом. Для измерения размеров дефектов использовалась рентгеновская томографическая установка, точность измерений которой была подтверждена результатами металлографического исследования.&#13;
Результаты. Испытаны 18 типов установок УЗК на пяти типах разделок сварных швов. Приведены развёртка сварного шва с индикациями обнаруженных дефектов и средние значения и дисперсия абсолютных ошибок измерения параметров дефекта. Дана классификация установок УЗК по аппаратной реализации контроля и методологии использования ультразвука.&#13;
Выводы. Проведенные испытания позволили определить допустимость применения каждой установки при строительстве и капитальном ремонте трубопроводов.</p>

    <p>Introduction. Qualification tests are carried out with the aim to understand real possibilities of NDT instruments to detect defects as well as calculate measurement errors at size measurements.&#13;
Method. Previous experience has shown that it is impossible to obtain defects with given parameters only by changing welding conditions. Defects were made mechanically or with electroerosive method. Size measurements were fulfilled with X-Ray tomograph; its measurement accuracy was confirmed by the results of metallographic study.&#13;
Results. 18 types of UT instruments have been tested on 5 types of weld grooving. Tests were fulfilled in accordance with DNV-OS-F-101 and DNV-RP-F118 standards. Welds’ unfoldings with indications of detected defects have been presented as well as average values and dispersion of absolute errors of defect parameters measuring. Classifications of UT instruments have been proposed – according to testing hardware implementation and to the methodology of ultrasound application. The results of NDT instruments qualification tests fulfilled in 2014 were used as the basis.&#13;
Conclusions. The fulfilled tests have made it possible to determine acceptability of each instrument for pipelines construction and repair.</p>
