ABSTRACT: Ultrasonic
testing is a very important non-destructive method for testing components for
safety of nuclear power plants and other security and delicate parts in other
industries. Nowadays, thanks to the development of computer technology, it is
possible to simulate processes which occur during ultrasonic testing. That is
why numerical simulations are becoming an integral part of non-destructive
testing. Simulations are used to determine parameters of ultrasonic
examination, especially parameters of probes and scan plan and also in the analysis
of results. They are used in such cases, when it is necessary to verify
applicability of probes and methods. This verification could be provided on the
weld and test block which are not manufactured. It could be also provided on
defects, which are not manufactured in test block, but their presence is
possible in given weld joint. Simulations are very useful for verifying the
propagation of ultrasonic signal in given area (e.g. weld area). If movement of
probe is limited, possibility of whole volume scan should be verified.
