Component`s defect inspecting method for , involves evaluating medium-run time between transducer and surface, and determining medium-run time and defect localization using transmitting condition and receiving condition

摘要

The method involves radiating a surface (4) of a component (2) by a liquid/gaseous flow medium (3) with an ultrasound radiation that is produced by a transmitting/receiving transducer (6). A part of the radiation is reflected back at the surface to the transducer, and return-sound radiation is received by the transducer. Medium-run time is evaluated between the transducer and the surface. The evaluated time is considered with a localization of a defect (5) within the component. Transmitting condition and receiving condition are used for determining the medium-run time and defect localization. An independent claim is also included for an arrangement for inspecting a defect of a component.
