FIELD: metallurgy.
SUBSTANCE: in build-up welding, the part is displaced relative to inductor, while inducing conductor of the latter is located along the arc of circle with its convex part facing the part displacement direction. Radius of said arc makes 0.5-2.5 of the built-up surface width, while lateral section of inducing conductor narrow section faces building-up drop surface with its axis of symmetry inclined to said surface at 25-115°.
EFFECT: surface-hardening and recovering worn-out parts, higher efficiency and quality of build-up welding, reduced power consumption and longer life.
