NDT Introductions

Nondestructive testing, or better known as NDT "Non Destructive Test" is a way to test the quality or condition of an object, goods or products without destroying the object.

In industry, the testing of an object are usually aimed at detecting discontinuities or defects on the surface, sub-surface or the inside of the object. Discontinuities can lead to a decrease in product quality and condition of the object, which in turn could threaten the safety. At this time a lot of nondestructive testing methods that have been and are being developed for this purpose.

Test visual, magnetic particle testing, penetrant testing and eddy current testing are some nondestructive testing methods typically used to detect the condition of the surface and sub-surface of an object, whereas the conditions inside the object can be detected using radiographic test or ultrasonic test.

Nondestructive testing is part of a chain of an inspection process. Inspection of a product is usually performed starting in the production of raw materials or finished products (fabrication / manufacturing) or on the product that is being used or operating conditions (in-service). Examples of fabricated products are molded product (casting), forging products (forging) and profuk welds (welding). Inspections are carried out to ensure compliance with the product standard or specification. In this case nondestructive testing is used as a means of "quality control". Inspection on the operating conditions do determine whether the object can be used.
