Ultrasonic Testing (UT) Services in Boksburg

What Is Ultrasonic Testing?

As a core component of our Non-Destructive Testing NDT Boksburg services, Ultrasonic Testing (UT) is one of the most powerful volumetric flaw detection methods available to industrial engineering firms in Gauteng. UT uses high-frequency sound waves (typically 1-10 MHz) to detect internal discontinuities — including cracks, inclusions, lack of fusion, and porosity — deep within solid materials.

How Ultrasonic Testing Works

During the UT process, a calibrated piezoelectric transducer emits high-frequency sound waves into the test material through a couplant medium. When the sound wave encounters an internal defect or the back wall of the component, it reflects back to the receiver. By measuring the signal amplitude and time-of-flight, our technicians calculate the exact depth, size, and location of the flaw with millimetre accuracy.

FlawTech utilizes advanced digital UT instruments with A-scan display, DAC curves, and DGS sizing techniques — ensuring our inspection results meet the stringent requirements of ASME Section V, API 1104, AWS D1.1, and SANS 10120.

The FlawTech UT Advantage

Ultrasonic Testing requires access to only one side of the material, making it highly versatile for complex geometries. Unlike radiography, UT does not use ionizing radiation — meaning it can be performed safely on crowded job sites across Gauteng without halting surrounding work or requiring an exclusion zone.
