FIELD: technological processes.
SUBSTANCE: invention relates to friction welding. To obtain a tool for friction welding with mixing of aluminum alloys with high processability, high reliability and durability during exploitation at a temperature of up to 500 °C, a part blank of tool steel with a hardness of not more than 25 HRC is grinded on the lathe to the required tool size with an envelope of 0.2 to 0.5 mm, subjected to a subsequent thermal treatment including quenching and tempering at a temperature of at least 500 °C with a hardness of at least 54 HRC after tempering and adjusting the tool to the required size by turning with the removal of the envelope.
EFFECT: tool for friction welding with mixing of aluminum alloys with high processability, high reliability and durability during exploitation is proposed.
