Abstract
1. Ультразвуковой способ снятия остаточных напряжений в сварных соединениях металлов и сплавов путем воздействия ультразвука на околошовную зону в процессе сварки, отличающийся тем, что для повышения эффективности снятия остаточных напряжений, а также повышения однородности структуры и прочностных свойств металла сварных соединений в процессе автоматической сварки орбитальным сварочным автоматом ультразвуковые преобразователи устанавливают и прижимают к поверхности объекта сварки в зоне термического влияния вдоль сварного шва на расстоянии друг от друга, равном зоне эффективного воздействия ультразвука каждого из ультразвуковых преобразователя. ! 2. Способ по п.1, отличающийся тем, что для получения возможности снятия остаточных напряжений в сварных соединениях металлов и сплавов большой протяженности в зоне термического влияния сварного соединения устанавливают два ультразвуковых преобразователя, один из которых поочередно прижимают к поверхности объекта сварки, а второй перемещают в направлении движения сварочного электрода и прижимают к поверхности объекта сварки на расстоянии, равном зоне эффективного воздействия ультразвука первого преобразователя. 1. An ultrasonic method for relieving residual stresses in welded joints of metals and alloys by the action of ultrasound on the heat-affected zone during welding, characterized in that to increase the efficiency of removing residual stresses, as well as to increase the homogeneity of the structure and strength properties of the metal of welded joints in the process of automatic orbital welding With an automatic welding machine, ultrasonic transducers are installed and pressed against the surface of the welding object in the heat-affected zone along the weld at a distance from each other equal to the zone of effective action of ultrasound of each of the ultrasonic transducers. ! 2. The method according to claim 1, characterized in that in order to obtain the possibility of relieving residual stresses in welded joints of metals and alloys of great length, two ultrasonic transducers are installed in the heat-affected zone of the welded joint, one of which is alternately pressed against the surface of the welding object, and the second is moved in the direction of movement of the welding electrode and pressed against the surface of the welding object at a distance equal to the zone of effective action of ultrasound of the first transducer.
