The application discloses a method and device for repairing cracks in conductive components, and relates to the technical field of crack repairs. The method for repairing the crack of the conductive member includes applying an electrical signal to both ends of the conductive member, and while applying the electrical signal, applying mechanical energy to the crack of the conductive member, and the mechanical energy is obtained by ultrasonic conversion. In this application, the mechanical energy converted by electrical signals and ultrasonic waves acts on the conductive member to be repaired at the same time, and the electrical signal produces Joule heating effect and electroplastic effect at the crack to soften the crack area; at the same time, the mechanical energy obtained by ultrasonic conversion acts on the crack of the conductive member , helps the material around the crack to fill the crack gap plastically, can realize the repair of the internal crack of the conductive component, and improve the crack repair effect.
Description
technical field [0001] The application belongs to the technical field of repairing component cracks, and in particular relates to a method and device for repairing cracks in conductive components. Background technique [0002] Among the various defects of metal materials, cracks are the most harmful. Cracks seriously affect product performance, which may cause damage, cracking and other problems in the application process of metal components. Major hidden dangers and threats. If the defects of the metal components can be repaired in time to restore the performance of the metal components, sudden and catastrophic serious consequences can be avoided, which will have great engineering significance and social and economic benefits. [0003] At present, the commonly used metal material crack repair technology is the repair welding method. The repair welding method is used to remove the part of the material containing the crack from the surface, and then melt the filling materia...
