Description

Известен способ предупреждени  образовани  холодных трещин при сварке закаливающихс  сталей путем предварительного подогрева околошовной зоны. Однако при этом нельз  получать качественное сварное соединение , так как в околошовной зоне углерод находитс  в основном в твердом растворе.A known method for preventing the formation of cold cracks during welding of hardening steels by preheating the heat-affected zone. However, it is not possible to obtain a high-quality welded joint, since in the heat-affected zone the carbon is mainly in solid solution.

Предложенный способ отличаетс  от известного тем, что участок околошовной зоны остывающего сварного соединени  подвергают воздействию ультразвуковых колебаний в интервале температур на 100-150°С выше температуры начала мартенситного превращени  и до комнатной температуры.The proposed method differs from the known one in that the portion of the heat-affected weld zone of the cooling weld is exposed to ultrasonic vibrations in the temperature range 100-150 ° C above the temperature of the beginning of the martensitic transformation and to room temperature.

В результате этого распад переохлажденного аустенита начинаетс  при более высоких температурах, интепсифицируетс  процесс отпуска , что приводит к изменению распределени  углерода между твердым раствором иAs a result, the decomposition of supercooled austenite begins at higher temperatures, the tempering process is absorbed, which leads to a change in the distribution of carbon between the solid solution and

карбидной фазой. Увеличение углерода в карбпдах приводит к значительному повышению стойкости закаливающихс  сталей против образовани  холодных трещин. Предлагаемый способ применим при всех видах сварки и наплавки закаливающихс  сталей.carbide phase. The increase in carbon in the carbides leads to a significant increase in the resistance of cold hardening hardening steels. The proposed method is applicable to all types of welding and surfacing of hardening steels.
