Abstract

Устройство и способ ультразвукового неразрушающего контроля предусматривают удлиненную ленту из проводящего ультразвук материала, присоединенную проксимальным концом к испытуемому объекту. Удлиненная лента имеет поперечное сечение с соотношением ширины и толщины больше единицы и согласованное с ультразвуковым преобразователем, возбуждение которого создает, по существу, не подверженный дисперсии ультразвуковой сигнал для распространения вдоль удлиненной ленты к проксимальному концу и вхождения в испытуемый объект. Эти не подверженные дисперсии импульсы в особенности пригодны для измерений времени пролета, измерений толщины, измерения трещин и т.п. Удлиненная лента помогает отделить преобразователь от возможной агрессивной среды, в которой находится испытуемый объект. Удлиненная лента также имеет большую площадь контакта с испытуемым объектом, создавая возможность эффективной передачи энергии в испытуемый объект.
