2.  Non destructive testing(NDT) is one
of the important methods used for
evolution and quality control of
metal components
 During testing, the metal component
does not get damaged
 These tests are used to locate or find
out the defects or flaws in the
component

3.  The equipments are easy to handle
 Defects can be detected without damaging the
components
 Methods are quick and accurate
 Components can be sorted out on the basis of
electrical, magnetic or chemical properties
 Test results and other information can be
conveniently recorded on paper films, cassettes
and floppies

4.  SOURCE
 MODIFICATION
 DETECTION
 INDICATION
 INTERPRETATION

5.  Thickness and lengths up to 30 ft can be
tested
 Position, size and type of defect can be
determined
 Instant test results
 Portable
 Capable of being fully automated
 Access to only one side necessary

6.  The operator can decide whether the test
piece is defective or not while the test is in
progress.
 Considerable degree of skill necessary to
obtain the fullest information from the test.
 Very thin sections can prove difficult.

7.  NDT is a new technology and system for industrial
inspection and testing
 Many developed countries uses this technology because of
its huge benefits
 Modern NDT methods will become just as an important
tool for risk based inspection approaches and maintenance
planning
 For this purpose every industry should have a NDT
division with NDT personnel
