UT sample questions and answers
What is ultrasonic testing? Ultrasonic testing is a non-destructive testing method that uses high-frequency sound waves to examine the integrity of a material or component.
What are the three main types of ultrasonic testing? The three main types of ultrasonic testing are pulse-echo testing, through-transmission testing, and immersion testing.
What is pulse-echo testing used for? Pulse-echo testing is used to detect surface and near-surface defects in a material or component.
What is through-transmission testing used for? Through-transmission testing is used to detect defects that are deeper within a material or component.
What is immersion testing used for? Immersion testing is used to detect defects in large, flat surfaces or in materials with poor surface conditions.
What is the frequency range of ultrasonic testing? The frequency range of ultrasonic testing is typically between 0.1 and 25 MHz.
What is the speed of sound in steel? The speed of sound in steel is approximately 5,500 meters per second.
How does the temperature of a material affect its ultrasonic testing? The temperature of a material can affect its ultrasonic testing by altering the speed of sound in the material.
What are the three main factors that can affect the accuracy of ultrasonic testing? The three main factors that can affect the accuracy of ultrasonic testing are the skill of the operator, the quality of the equipment, and the condition of the test surface.
What is a couplant used for in ultrasonic testing? A couplant is a liquid or gel that is used to improve the transmission of ultrasonic waves between the transducer and the test object.
