It is shown what happens to the base metal of the pipeline if it is clad with surfacing under normal operating conditions and the obtained stresses and strains are investigated. The influence of surfacing on the through crack in the pipeline was investigated and its influence on a crack opening was also studiedpipelinesurfacingcrack openingstrainтрубопроводнаплавкараскрытие трещиныдеформация
