摘要：Non-destructive testing techniques are the preferred techniques in this new era of development and progress.Health monitoring of different mechanical and civil structures during its service is very important for the safety ofhuman beings. Health monitoring of these structures using ultrasonic technique is an emerging field. It uses highfrequency sound waves into the material to detect and locate defects, discontinuities in the material. This paper presentsthe use of pulse echo technique of ultrasonic to detect corrosion defect in mild steel plates and the behaviour ofdifferent frequencies at various levels of corrosion. For different damage types, most ideal modes and frequencies wereselected for testing.
