Ultrasonic Testing-UT

Principals:

Reflection of Sound beam by a flaw gives signal on the oscilloscope.

Equipment Needs:

Pulse-echo instrument capable of exciting a piezoelectric material and generating ultrasonic energy within a weld ,and a suitable cathode ray tube scope capable of displaying the magnitudes of received sound energy. Calibration standards,liquid couplant.

Application:

Most weld discontinuities including cracks,slag and incomplete fusion.Can also be used to verify weld thickness.

Advantages:

Most sensitive to planar type discontinuities
.Test results known immediately
.Portable
.Most ultrasonic flaw detectors do not require an electrical power outlet .High penetration capability.

Limitation:

Surface condition must be suitable for coupling of transducer
• Couplant (liquid) required
• Small thin welds maybe difficult to inspect
• Reference standards are required.
Requires a relatively skilled operator or inspector.
