Abstract
The features of application of resistance measurement effect for investigation of the welding thermal cycle are considered. Practical recommendations are given to eliminate the ambiguity of evaluation of the sample reisistance which arises in Curie point transition. The structural-fuctional diagram of the sample temperature measuring device is described which is based on an alternating current double transformer bridge with quasimodulation balancing, capable of providing the measurement rate of >400 counts per second with <1.0 % error. This device is the basis for a computerized facility for thermal cycle of welding (TCW) investigation.
Keywords: arc welding, thermal cycle of welding, resistance measurement effect, instrument transducer, sensor
