FIELD: restoration of threaded holes.
SUBSTANCE: invention relates to the field of repair of threaded connections, namely to the restoration of threaded holes without changing the original dimensions of parts with external threads. The method for restoring threaded connections is provided by cutting the nut, while the thickness of the cut is equal to the thickness of the removal of a part of the nut material. The cut parts of the nut are connected and fixed on the screw and connected by welding, while the screw is a guide element for the connected parts of the nuts. When repairing a threaded joint, parts of the nut on the screw are seized by welding, without damaging the screw. After tacking the cut parts of the nut by welding, the screw is turned out and the mating parts of the nut are welded.
EFFECT: restoration of mating in a threaded connection by removing part of the material of the nut, that is, by repairing the nut.
