The detection, isolation, and characterization of flaws in components represent a critical need in manufacturing and quality control. Nondestructive testing (NDT) provides an effective way of inspecting materials for ensuring the quality and integrity of products and systems. Consequently, nondestructive inspection finds extensive application in several industries such as steel, nuclear and ele...

Abstract As a kind of nondestructive testing technology, stress wave technology has the advantages long propagation distance, strong anti-interference ability and convenient use, become one important means to detect wood properties defects at home abroad. This paper introduces several equipment commonly used in field non-destructive this stage, analyzes its characteristics. The research status ...

Nondestructive testing (NDT) is an advanced and commonly used technique in tunnel engineering quality inspection. To achieve good application of nondestructive technology, its main inspection strategy analyzed, including the significance applying technology inspection, applied test analysis, analysis strategy. The analyses this paper are done hopes providing scientific reference for utilization...
