Ultrasound Thickness Measurement in Alberta, Canada

Ultrasonic Testing (UT) is a thickness-measuring non-destructive testing (NDT) technique used to determine the thickness of materials or structures using ultrasonic waves. It is commonly employed in various industries, including manufacturing, construction, and maintenance, to assess the thickness of components such as pipes, tanks, vessels, and structural steel elements.

The ultrasound thickness measurement process involves the following steps:

1. Probe Selection: A suitable ultrasonic thickness gauge or probe is selected based on the material type, surface condition, and the thickness range to be measured. Probes may vary in frequency and shape to accommodate different applications.

2. Coupling Medium Application: A coupling medium, typically a gel or couplant, is applied to ensure efficient transmission of ultrasonic waves between the probe and the material being measured. This helps eliminate air gaps and ensures good acoustic coupling.

3. Probe Placement: The probe is placed on the material surface, and the ultrasonic waves are emitted into the material. The waves propagate through the material and reflect back from the opposite surface or an internal boundary, such as the back wall.

4. Wave Reception and Analysis: The ultrasonic waves received by the probe are converted into electrical signals and analyzed by the thickness gauge instrument. The time taken for the waves to travel through the material and return is measured.
