Abstract
The ideology of formalising decision making on the scope and terms of repair of welded structures by using their technical diagnostics data is considered. It is based on prediction of the probability of failure due to detected defects for a forthcoming period of operation, and is combined with the advanced risk analysis tools developed in allied activity fields.
Keywords: risk analysis, technical diagnostics, detected defects, failure probability
