FIELD: mechanical engineering; welding nuclear engineering.
SUBSTANCE: invention relates to resistance butt-welding of tubular jackets with plugs at sealing of rod-type elements of nuclear reactors. Device for forming of joints contains current supply and shaping parts in which hole is made form end of tubular jacket. Current supply and shaping parts are made integral in form of metal non-split plate or metal split plate divided into sectors along planes passing through hole for end of tubular jacket. Diameter of hole for end of tubular jacket in current supply part is either equal to or greater than diameter of hole in shaping part.
EFFECT: simplified design of device, improved reliability in operation and quality of welding.
