For accurate flaw sizing TOFD
is one of the most accurate techniques especially for internal defects.
For screening and sizing since TOFD can detect all the flaws in the beam
coverage irrespective of orientation it has a high probability of
detection. The fact that inspection data is collected in B or D-scan
form also improves the detection of cracks, in the presence of signals
from geometric features such as mismatch, and weld defects such as
excess penetration or undercut.
Change Monitoring
TOFD is one of the most accurate methods available for measuring the
growth of flaws.
TOFD is fast becoming the most preferred inspection method in the search
