摘要

(57) Abstract It is the thermal imagery conversion system (80) in order to detect the crack (100) and the defect in the component (82). Electromagnetic acoustic transducer (EMAT) (84), is connected by the component (82), leads the correspondence number of pulse condition in that. Defect (100) is heated by this correspondence number, IR emission (98) from of the component (82) is detected by the thermal camera. Amplitude of the pulse condition signal is fixed substantially, frequency of the pulse condition signal can change inside the respective pulse. Making use of control unit, timing and control of the operation of EMAT (84) and the camera are offered.
