Non-destructive testing, also known as non-destructive testing, refers to the use of changes in physical quantities such as heat, sound, light, electricity, magnetism, etc., caused by the abnormal internal structure of the material or the existence of defects, to detect various projects without damaging the tested object. Internal and surface defects of materials, parts, structural parts, etc.


The biggest feature of non-destructive testing is that it can be tested without damaging the material and structure of the test piece. Therefore, after the implementation of non-destructive testing, the inspection rate of products can reach 100%.


Moreover, with the rapid development of the manufacturing industry, the requirements for product quality inspection are getting higher and higher, and it is necessary to conduct strict flaw detection and accurate measurement of internal structure dimensions for more and more key, complex components and even product internal defects.


It can quickly, accurately and intuitively find the internal defects of the product. Defects such as cracks, pores, looseness, inclusions, etc., and analyze to find the root cause of the defects, thereby improving product performance and extending product life.


However, not all items and indicators that need to be tested can be NDT, and NDT technology also has its own limitations. Some tests can only use destructive tests, therefore, non-destructive testing cannot replace destructive testing at present. That is to say, for the evaluation of a workpiece, material, machinery and equipment, the results of non-destructive testing must be compared and matched with the results of destructive testing in order to make an accurate assessment.


In the past, the term non-destructive testing was first called flaw detection or non-destructive testing, and its different methods were also called flaw detection, such as radiographic flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetrant flaw detection and so on. This term or writing method is widely circulated and has been used to this day, and its usage rate is no less than that of non-destructive testing.
