A Method for Assessing the Operational Reliability of Welded Connections From 09g2s Steel Working in Environments Causing Corrosive Cracking

Abstract

Based on the study of the structure and mechanical properties of the metal of welded joints of 09Г2С steel, a metallographic method has been proposed, which makes it possible to establish the fact of post-weld heat treatment when determining the causes of corrosion cracking in aggressive environments of petrochemical and oil refineries, as well as supervising welding operations.
