Non-Destructive Evaluation for Internal Defect of Metal Casting

Abstract:

An NDE measurement for internal defects of metal casting products is presented. An experimental system for ECT is developed in order to inspect internal defects of brass casting which have complicated and inaccurate shapes. In the measurement, artificial defect specimen made for fundamental experiments and brass casting specimens are evaluated by multi-frequency excitation and spectrogram (MFES) method. From the results, validity of our measurement system is discussed.
