NDT introduction

NDT is the use of special equipment and methods to learn something about an object without harming the object. The term nondestructive testing usually implies that a nonliving object, such as a piece of metal, is being evaluated.

 

NDT methods are used to make sure that important parts on airplanes, automobiles, nuclear power plants, petroleum and chemical industry’s to name a few are free of defects that could lead to an catastrophic event.

 

NDT is also used in many other industries to make sure that parts do not have defects that would make the customer unhappy.

 

NDT is based on the scientific principles of physics and chemistry ( i.e sound, electricity, X-ray, magnetism etc.)

The field of Nondestructive Testing(NDT) is a very broad, interdisciplinary field that plays a critical role in assuring that structural components and systems perform their function in a reliable and cost effective fashion.

 

NDT technicians and engineers define and implement tests that locate and characterize material conditions and flaws that might otherwise cause planes to crash, reactors to fail, trains to derail, pipelines to burst, and a variety of less visible, but equally troubling events.

 

By that means detecting flaws at early stages. Equipment can be scheduled for repairs or replacement prior too failing to maximize the use of equipment, maximize productivity and cost savings from unexpected failures.

 

These tests are performed in a manner that does not affect the future usefulness of the object or material. In other words, NDT allows parts and materials to be inspected and measured without damaging them. Because it allows inspection without interfering with a product’s final use, NDT

provides an excellent balance between quality control and cost-effectiveness.

 

Generally speaking, NDT applies to industrial inspections. While technologies are used in NDT that are similar to those used in the medical industry, typically nonliving objects are the subjects of the inspections.
