FIELD: metallurgy.
SUBSTANCE: remelting of parent metal along surface fracture of contact point or seam welder is carried pout with production of solid fused nugget. Welding-up is performed along entire length of the fracture to overlap produced said core by, at least, 30%. Note here that filler wire is laid under contact point or seam welder electrode along surface fracture. Filler wire is connected with ultrasound transducer concentrator via slide contact. High-intensity ultrasound oscillations are fed during the entire cycle.
EFFECT: expanded operating performances, higher efficiency and quality of repair.
