FIELD: non-destruction flaw detection of metallic articles.
SUBSTANCE: apparatus includes heater acting upon heated electrode; cold electrode being inspected article; analog amplifier connected with indicator. Second cold electrode being reference sample has electric contact with second heated electrode and with inspected article that has contact with first heated electrode thermally connected with heater. Both heated electrodes are connected to analog amplifier whose outlet is connected with comparator and second indicator connected in series. Threshold value regulator is connected with comparator.
EFFECT: improved reliability of inspecting metallic articles.
