ULTRASONIC EXAMINATION
Description
Sound waves are transmitted into a material which allows for material characteristics to be determined based on the characteristics of the sound wave as it travels back and forth within the material. Transducer selection and search unit characteristics need to be determined based on the operational history, material characteristics, and intended outcome of the examination.
