NDT:
Nondestructive testing (NDT) Is the process of inspecting, testing or Evaluating Materials, Components or Assemblies for Discontinuities, or Differences in Characteristics without destroying the Serviceability of the part or system. In Other Words, when the Inspection or Test is completed the part can still be used.
Today modern nondestructive tests are used in manufacturing, fabrication and in-service inspections to ensure product integrity and reliability, to control manufacturing processes, lower production costs and to maintain a uniform quality level. During construction, NDT is used to ensure the quality of materials and joining processes during the fabrication and erection phases, and in-service NDT inspections are used to ensure that the products in use continue to have the integrity necessary to ensure their usefulness and the safety of the public.
NDT Test Methods:
Test Methods Names often refer to the type of penetrating medium or the Equipment used to perform that test. NDT is a cost-effective and reliable technique in a wide range of applications which aid in the delivery of quality products and cost-effective plant maintenance. Selecting the appropriate Method for a particular application requires care and understanding since all NDT Methods have limitations that must be well understood to ensure the desired reliability of inspections.
In Nondestructive Testing Industry, there are above than 35 different methods to inspect the tool. but the most frequently used test methods are-
NDT has an important role to play in the Quality Assurance, condition monitoring and maintenance programs of many organizations. In these tutorials, the variety of typical examples will be examined and discussed, considering the importance that the correct NDT technique be selected and defect rejection/acceptance criteria be relevant to the material and its application. Quality Control is required to ensure reliable use of NDT techniques because failure can have devastating results.
