Preparatory Notes for ASNT NDT Level III Examination - Ultrasonic Testing, UT

• Operation is electronic, which provides almost instantaneous indications of
flaws. This makes the method suitable for immediate interpretation,
automation, rapid scanning, in-line production monitoring, and process
control. With most systems, a permanent record of inspection results can
be made for future reference
• Volumetric scanning ability, enabling the inspection of a volume of metal
extending from front surface to back surface of a part
• Nonhazardous to operations or to nearby personnel and has no effect on
equipment and materials in the vicinity
• Portability
• Provides an output that can be processed digitally by a computer to
characterize defects and to determine material properties
