ultrasonic flaw detector is not only used for detecting
sufrace defects but also used to find out inclusions,
delaminations at the exact locations([particular depth).
Based on A-scan and c-scan method we can find out the depth
of damage, inclusions, porosity and other defects.
there is limitation that it can,t be used for irregular
sufraces because it causes more attenuationa and scattering
of sound waves.
