Problems solved by technology

Further, latent defects may not be detected by using x-ray or ultrasonic inspection
For example, x-ray inspection may not be able to detect or reveal cracks in a part due to the geometry or variable density of the part
Additionally, x-ray inspection may not be able to detect cracks oriented orthogonally to the x-ray detector array
As another example, inhomogeneities or latent defects in geometry / materials may create additional echoes or shadows, making ultrasound or x-ray data expensive to analyze and making detection of inconsistencies / defects difficult

Embodiment Construction

[0013] The disclosed examples will now be described more fully hereinafter with reference now to the drawings, in which some, but not all disclosed examples are shown. In fact, some different examples may be provided and should not be construed as limitations to the examples presented herein. Rather, these examples are provided so that this disclosure will be thorough and complete and will fully convey the scope of the disclosure to those skilled in the art.

[0014] Within an example, systems and methods for inspecting radiography of materials and assemblies are provided. For example, systems and methods may facilitate detection of voids, cracks, or other defects in materials and assemblies. As described herein, the systems and methods utilize the ability of radioactive or isotopically labeled fluids to penetrate through materials or assemblies in order to detect the presence or absence of internal defects in the materials or assemblies. The systems and methods described he...

Abstract

Example systems and methods for testing materials and assemblies for voids, cracks, or other defects are provided. One example system for testing a part includes a chamber configured to accept the part, and a vacuum source connected to the chamber. The example system also includes a fluid source connected to the chamber and configured to provide a radioactive or isotope-labeled fluid to the chamber. In addition, the example system includes a detector configured to detect a presence or absence of radioactivity or the isotope-labeled fluid in the part.

Description

technical field [0001] The present disclosure relates generally to radiographic systems and methods for inspecting materials and assemblies, and more particularly to radiographic systems and methods for detecting voids, cracks, or other defects in materials and assemblies. Background technique [0002] Proof testing is a non-destructive testing technique used to verify that a part, component or assembly is suitable to withstand the conditions in which it is designed to function. By way of example, a proof test may include subjecting the part to twice the maximum design load of the part and seeing if the part is damaged in any way. Manufacturers in many industries use proof testing as a way to screen parts for manufacturing anomalies before allowing them to go through "inspection" and be put into service. Similarly, proof testing can also be used to verify that older parts are still functioning properly and are suitable for additional service. [0003] In some examples, a p...
