Methods and advantages of Ultrasonic testing

Published On November 12, 2021 | By admin | Technology

Ultrasonic testing is one of the non-destructive testing techniques performed with the transmission of ultrasonic waves in the component set to test. This testing is widely used in many industries like manufacturing, metallurgy, automotive, aerospace, and transportation sectors. This is often performed on metals like steel and alloy but can also be performed on wood, stones, and concretes but with reduced resolution.

Methods of ultrasonic testing:

Contact ultrasonic testing:

Contact ultrasonic method allows accessing specimen who are irregular shaped and immobile. This method is performed where only one side of the specimen is reachable or the components to be checked are immovable, large, and irregular in shape.

Immersion Ultrasonic Testing:

It is laboratory-based testing that is appropriate for inspection on curved and complex surfaces. In this technique, water is used as a substitute for a gel which is used in contact ultrasound. This technique employs pulse-echo and robotic probes to test complex surfaces which would be hard to keep up with contact probes.

Advantages of ultrasonic testing:

High probing power and sensitivity:

Ultrasonic waves are powerful and allow deep inspection within the specimen. Its sensible nature allows inspecting even the minor details and flaws for a clear reflection.

Less time consuming:

Due to its powerful inspection, sometimes, it requires only one dimension of testing. It can subtract the time by its ability to estimate the size, structure, and nature in just one or two tests. It gives immediate results, allowing immediate reflection for further decisions.

Convenient for immovable specimens: 

This made NDT access anywhere as it allows inspection of immovable specimens by its flexible and portable nature. It is the best form of testing for specimens that are irregular in shape and impossible to move from their place.   

Safe and accurate:

Ultrasonic testing is non-hazardous, for every aspect during the inspection as it does not harm any creature or the specimen. It provides greater accuracy, as it reflects the exact details of the reflection of specimen’s most accurate nondestructive testing out of all the other testing methods.
