METHOD OF CONNECTING WIRES MADE OF MATERIALS WITH DIFFERENT PHYSICAL AND CHEMICAL PROPERTIES Russian patent published in 1997 - IPC

FIELD: different industries; production of thermocouples. SUBSTANCE: when manufacturing a thermocouple, for instance, copper-constantan, rectifying element (diode) and variable resistor are placed in arm of thermoelectrode with smaller specific resistance which makes it possible to level electric resistance in arms of thermoelectrode to be welded and to correct welding temperature conditions. Simultaneously when welding thermocouple electrodes, direct and alternating voltage is used. EFFECT: enlarged operating capabilities. 1 dwg
