How does ultrasonic testing help?

 Do you have any idea about any testing we can perform without object destruction? There is one such technique called non-destructive testing method which we can use. It is ultrasonic testing which is the best to detect flaws and defects without damaging the object. This test is one of the best to check for any corrosion or defects. 

You can avoid part failure or destruction of the entire asset by using it periodically. As a result, you can find its application in the various industries.


What is Ultrasonic testing?


Ultrasonic testing is a non-destructive testing method that uses sound waves to detect thickness, cracks and defects in components and materials. For example, this method is effective for determining the pipe thickness and wall thickness.


What is the working principle of Ultrasonic testing?


Ultrasonic testing uses a piezoelectric transducer that transmit and receive ultrasonic waves. It is the basic form of a pulse-receiver and oscilloscope display. The transmitter pulse ultrasonic wave into the material and reaches the backwall and wave is reflected and received by the receiver. The test can be performed via two basic methods: Pulse-echo and Through-transmission.


  1. Pulse-echo – The transmitter generates an ultrasonic pulse wave which is reflected by an inhomogeneity like a defect or the back wall of the test sample, and obtained by the receiver.


  1. Through transmission – A transmitter probe on one side of a component transmits an ultrasonic pulse to a receiver probe on the other side. The absence of a pulse coming to the receiver indicates a defect.


Where is it used?


Ultrasonic testing is widely use across various industries like aerospace, automotive, construction and etc. It can be applied on both ferrous and non-ferrous materials to detect defects and flaws in the materials, as well as thickness of the materials. 


Final Statement-


It is one of the best NDT methods to detect flaws and defects in the material. Without damaging objects, one can conduct the test easily. Want to know more about the topic? You can connect with the experts of Industrial-ndt.com (INDT). Visit the portal today.

Use of Ultrasonic Testing in the Power Generation Industry

Ultrasonic testing is a method used for determining the thickness of a structure with the help of sound waves. These sound waves are of high frequency, and this method is a reliable non-destructive method used in the power generation industry. There is no need to cut the test piece or use any chemical that might deteriorate it. The sound waves travel through the surface of even sturdy metals and help determine the thickness.   How does Ultrasonic Testing work? High-frequency sound waves that are way beyond the limit of the human ear get induced in this non-destructive testing technique. The test is performed under the supervision of an expert only. They can do the setup with proper requirement standards. Devices are used to induce the sound waves into the material in question. These sound waves can penetrate through any surface except for paper or wooden products. After passing through the surface, the sound wave is reflected when hitting the boundary and is returned to the so

What does paint thickness gauge do, and how is it useful?

A coating thickness gauge, also known as paint thickness gauge or paint meter is used to measure thickness of the dry film. Dry film thickness is the most complicated thickness measurement in the entire coating industry because of its impact on the quality, coating process, and cost. Such measurements can be used to evaluate the expected life of the coating, the appearance, and the performance of the product. The measurement further ensures the compliance of the product with all the international standards. A paint thickness gauge uses different principles and mechanisms, and the ultrasonic principle is one of them. This technique is used for measuring the thickness of the paint on all the non-metal substrates like fiberglass and plastic. The probe of the instrument comprises an ultrasonic transducer that works by sending a pulse throughout the coating. This pulse then reflects from the substrate to the transducer and is further converted into a high-frequency electric signal. It is t

What are the advantages of eddy current testing?

  Different industries perform various testing techniques to infer details like identifying product flaws, measuring material thickness, detecting metals, and more. Many significant decisions related to production depend on this information. Hence, they take it very seriously. However, most industrial experts opt for non-destructive techniques like eddy current testing as they are safe and reliable.  What is eddy current testing? This technique is ideal for testing conductive materials with the help of the electromagnetic induction principle. The magnetic field is built around the material under investigation that oscillates to develop the alternating current into the coil that induces current into the specimen. The change in conductivity of the material due to the induction of eddy currents allows the experts to interpret the data and identify defects. For example, it will help know the thickness, check for flaws inside the metal and other condition information. Advantages of u
