Introduction to Nondestructive Testing - SkillsCommons

What is nondestructive testing? NonDestructive Testing (NDT) is the process of doing inspections, testing, or evaluating materials, components or assemblies for defects without destroying the material or component. Or the use of noninvasive techniques to determine the integrity of a material, component or structure
