FIELD: mechanical engineering; manufacture of devices for contact butt welding of pipes with plugs for sealing rod-type fuel elements of nuclear reactors.
SUBSTANCE: proposed method consists in stacking the current lead, stop-cooler made from set of metal plates at increased electric resistance and holder made from dielectric material. Stack thus made is subjected to machining and to aging by welding the specimens. Stop-cooler is electrically shunted by means of plate-type shunts located in holes made over perimeter of device. Plate-type shunts are rolled in cylinder and are fixed in holes by releasing deformable electric plugs fitted in these holes.
EFFECT: reduced labor consumption; enhanced operational stability; extended functional capabilities.
