FIELD: plastic working of metals, namely manufacture of hollow spherical parts.
SUBSTANCE: method comprises steps of filling blank with melt filler poured into annular cavity formed by means of blank and rod coaxially arranged inside blank; using filler whose melting temperature is less than that of blank material; cooling filler until solidifying it; squeezing and forming blank with filler in semi-spherical dies; then heating filler and removing it out of formed spherical part.
EFFECT: lowered energy consumption due to reduced mass of filler.
