HEAT FLAW DETECTOR FOR NONDESTRUCTIVE TESTING OF WHEELS STATE OF RAILWAY AND SUBWAY CARS

摘要

nondestructive testing instruments. SUBSTANCE: heat flaw detector provided with infrared imager has electrode for connecting one of poles of DC power supply source to point of geometric center of tested wheel and electrodes for connecting to the other pole of DC power supply source. Electrodes are uniformly distributed and rigidly connected to surface of metal hoop designed for fitting onto tested wheel. EFFECT: simplified design of heat flaw detector. 2 dwg
