Ultrasonic Testing

Ultrasonic testing (UT) uses sound waves to find internal flaws and measure wall thickness from one side of a part. The range includes ultrasonic flaw detectors, thickness gauges with and without A-scan and B-scan display, probes, and calibration blocks such as V1, V2, IOW and step blocks.

Typical applications

• Weld inspection
• Corrosion and wall-thickness surveys on pipes, tanks and vessels
• Internal flaw detection in castings, forgings and plate
• Instrument set-up and checks with calibration blocks

Choosing equipment

Key factors are whether you need flaw detection or thickness measurement only, the material and thickness range, the surface condition and temperature, the probe type and frequency, and whether readings or scans must be stored.
