FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: invention relates to method of manufacture of carriers of catalytic converters used in engine exhaust systems for neutralizing exhaust gases forming at operation of internal combustion engines. Invention contains description of method of manufacture of cellular element with tubular casing and flange part for fastening pickup to tubular casing. According to proposed method, tubular casing is made from metal sheet, and hole is made in metal sheet at predetermined place. Hole is provided with limiting edge, and flange part is fitted on hole edge in tubular casing. Cellular structure is placed in tubular casing. Tubular casing with cellular structure and flange part are subjected to thermal treatment to connect them to each other. Invention provides integration of process of connection of flange part with tubular casing into existing thermal treatment process.
EFFECT: simplified and accelerated process of manufacture of cellular elements, thus reducing costs.
