Ultrasonic Testing

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.

case study :

Client Introduction:

Steel plate distributors

Problem:

Customers ask why the end users are asking for ultrasonic inspection even though there's no requirement in the mill certificates.

Problem:

Customers are asking why the need for additional blocks to be fabricated.

Solution:

Justifying to the clients and explaining to them that ultrasonic inspection is at times used as a secondary justification for the item to be re-tested

Solution:

We assure them that it's under the requirements of the specifications to which they want to comply. We cannot adhere to the specification without using the referenced/calibration blocks.

review :

- Though the cost is more expensive than most, the PTS team gives the customer confidence regarding how we conduct our testing.
- By assuring the clients that all the discussion and all the back-end preparation are done before the testing.

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.

High penetrating power

Detection of extremely small flaws

Only one surface needs to be accessible.

Common Test Methods

ASTM A388/388M

ASTM A435/A435M

ASTM A578/A578M
