Ultrasonic testing - Study guides, Class notes & Summaries

Ultrasonic Testing Final Exam The velocity of sound in a material is dependent upon the: - - Material Properties To vary or change the wavelength of sound being used to test a part, you would change the: - - Sound-wave Frequency Ultrasonic vibrations are commonly used to examine materials for: - - Discontinuities The number of complete waves which pass a given point in a number of cycles per second is referred to as the: - - Frequency of a wave motion Sound waves with a frequency beyond h...

1. The indication on the instrument display that represents the far boundary of material being tested is called: - the back-surface reflection. 2. In immersion testing, the position of the transducer is often varied by a manipulator to transmit sound into the test part at various angles to the front surface. Such a procedure is referred to as: - angulation. 3. The technical name for the cable that connects the ultrasonic instrument to the transducer is: - coaxial cable 4. The process of s...

Ultrasonic waves propagate through test materials in the form of: - ANSWER-mechanical vibrations When an ultrasonic beam passes through the interface of two dissimilar materials at an angle, a new angle of sound travel takes place in a the second material due to : - ANSWER-refraction The gradual loss of energy as ultrasonic vibrations travel through material is referred to as: - ANSWER-attenuation Ultrasonic velocities are different for different materials. These difference are primaril...
