Nondestructive inspection
Nondestructive testing is a physical measurement carried out without damaging the original shape or function of industrial materials and products in order to find various defects and flaws in them, and nondestructive inspection is a method of determining whether the material can be used further based on the results of this test. In reality, however, the two are often used interchangeably. There are various test and inspection methods, and currently, (1) radiographic testing, (2) ultrasonic testing, (3) magnetic testing, and (4) penetrant testing are used. (1) and (2) are effective for detecting internal defects, (3) is effective for inspecting defects near the surface, and (4) is effective only for defects and flaws that are open to the surface of the object.
