Reasons for crack nucleation in welded joints of main gas-pipelines after a long-term operation

Abstract

crack of operational origin in the welded joint of the main gas pipeline is analyzed. The reasons for its nucleation and impact on technological microdefects that were formed earlier during the welding are found. Micromechanisms and stages of nucleation and propagation of the crack are investigated.
