Using ultrasonic waves to inspect the material
Ultrasonic Testing (UT) is a non-destructive test method capable of characterising a test piece’s internal structure and discontinuities through high-frequency sound waves. It utilises ultrasonic waves to detect cracks and defects in parts and materials. It can also be used to determine material thickness, such as measuring the wall thickness of a pipe.
Ultrasonic weld testing is part of weld quality control and is crucial for ensuring safety in various industries. Our NDT operators can use ultrasonic flaw detectors to locate and characterise discontinuities within the weld that might lead to material or component failure.
One of the most valuable characteristics of ultrasonic testing is its ability to determine the exact position of a discontinuity in a weld. This testing method can be used on ferrous and nonferrous materials, is often suited for testing thicker sections accessible from one side only, and can often detect more refined lines or plainer defects which may not be as readily detected by radiographic testing. This testing method requires a high level of operator training and competence and depends on establishing and applying suitable testing procedures.
Advantages of Ultrasonic Testing
High penetrating power, which allows the detection of flaws deep in part
High sensitivity, permitting the detection of small flaws
In many cases, only one surface needs to be accessible
Some capability of estimating defects' size, orientation, shape and nature
No potential health hazards
The results are immediate, highly repeatable and reliable.
