UT Level II - General (3)
UT Level II Ultrasonic Testing Quiz
Welcome to the UT Level II Ultrasonic Testing Quiz, designed to assess your knowledge in ultrasonic testing fundamentals and techniques. This quiz features 11 carefully crafted questions that cover theoretical and practical aspects of ultrasonic testing.
Participate and see how well you understand concepts related to A-scans, beam divergence, acoustic impedance, and more!
- Test your knowledge on key ultrasonic testing principles.
- Evaluate your readiness for certification.
- Gain insights into your understanding of ultrasonic wave behavior.
In an A-scan presentation, the horizontal line formed by the uniform and repeated movement of an electron beam across the fluorescent screen of a cathode ray tube is called
A square wave pattern
A sweep line
A marker pattern
None of the above
The angle at which Longitudinal wave travel on the surface or 90❰, such angle is called as:
Refracted angle
First critical angle
Second critical angle
Mode converted angle
Angle of beam divergence will change if
Frequency and size of probe is changed
Type and length of cable is changed
Gain and pulser voltage is changed
Both a & c
If the acoustic impedance of a material is high
Ultrasonic waves will be highly attenuated in that material
Ultrasonic waves will travel slower in that material
Ultrasonic waves will travel fast in that material
Both a & b
When damping of the probe is increased, the frequency bandwidth
Remains the same
Increases
Decreases
Depends on the equipment
The angle marked on an angle probe is
The angle of the plastic wedge of the probe
Second critical angle
First critical angle
Angle of refraction in steel
Which of the following cannot be determined by using an IIW(V1) block :
Sound path distance
Beam spread
Exit point of the transducer ( probe index)
Angle of refracted shear wave
To scan the root area of a double sided weld you would employ
70 degree probe
60 degree probe
45 degree tandem technique
A or c
On an A-scan display, the "dead zone," refers to:
The distance contained within the near field
The area outside the beam spread
The distance covered by the front surface pulse width and recovery time
The area between the near field and the far field
The velocity of sound in a material is dependent upon the:
Frequency of the wave
Wavelength
Material properties such as density and elasticity
Vibration cycle
