FIELD: measurement equipment.
SUBSTANCE: application: to detect depth of local corrosion and track its development. One or several converters of acoustic emission are installed onto controlled item, signal oscillogram is registered, differs by the fact that signal oscillogram is used to define share nso of symmetric So Lamb wave in signal and/or share of nA0 of antisymmetric Ao Lamb wave in signal, an share or shares produced as well as their ratio is used to understand depth and development of corrosion.
EFFECT: improved information capacity of the corrosion defect detection process with the help of acoustic emission even by one signal produced at least by one converter of acoustic emission.
