ABSTRACT

Based on experimental investigations using methods for assessing the technological strength of welded joints, an attempt made to impact assessment the effect of hydrogen localization and its role in the emergence of a process of delayed fracture. It is established that delayed destruction has a staged process of destruction. It is shown that welding in the naturally low temperature is one of the conditions for the emergence of delayed fracture.
