PROCESS OF MANUFACTURE OF THERMOCOUPLES Russian patent published in 1998 - IPC

FIELD: measurement of temperature of fast-going processes. SUBSTANCE: given process can be used in manufacture of thermocouples enabling temperature of fast-going processes in objects with high temperature gradient to be taken. Diffusion welding is employed to butt-weld butts of two bars made of different materials or alloys. Turning tool takes away layer of joined metals so that weld is positioned along manufacture band. Hammering reduces level of roughness of band to specified value, then band is rolled along weld and thermocouple is cut out of it. EFFECT: thermocouple so manufactured displays low sluggishness and provides for high accuracy of measurements. 2 dwg , 1 tbl
