Description
Известно применение наклепа при сварке сталей.Known application of work hardening when welding steels.
Предлагаемый способ отличаетс тем, что поверхность свариваемого металла подвергаетс нредварительному наклепу. Благодар процессу наклепа при сварке происходит прочное соединение основного металла с металлом шва.The proposed method is characterized in that the surface of the metal to be welded is subjected to premature work-hardening. Due to the process of work hardening during welding, a strong connection of the base metal with the weld metal occurs.
Дл снижени остаточных напр жений и рекристаллизации сварные детали после наклепа подвергают последующей термической обработке- аустенизации, заключающейс в нагреве стали до 1050-1100° и последующей выдержке при 870-900°.To reduce the residual stresses and recrystallization, the welded parts after work hardening are subjected to subsequent heat treatment-austenization, which consists in heating the steel to 1050-1100 ° and subsequent aging at 870-900 °.
Применение при сварке указанного способа позвол ет эффективно повышать эксплуатационную прочность сварных соединений кованых аустенитных сталей.The use of this method in welding makes it possible to effectively increase the operational strength of welded joints of forged austenitic steels.
