Ultrasonic Testing (UT) uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more.
Advantages
- High penetrating power, so that detection of flaws deep in the part.
- High sensitivity, permitting the detection of extremely small flaws.
- Greater accuracy than other nondestructive methods in determining the depth of internal flaws and the thickness of parts with parallel surfaces.
- Some capability of estimating the size, orientation, shape and nature of defects.
- Nonhazardous to operations and has no effect on equipment and materials in the vicinity.
- Capable of portable or highly automated operation.
