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 using this testing technique

There are plenty of reasons to opt for this testing method as it offers many benefits.

·       It can detect minor defects which no other testing technique can identify. A crack that is less than 0.5mm in size is also detectable with eddy current testing. 

·       Able to detect defects through multiple layers, with surface coatings.

·       Able to test on metals with complex internal structure and geometry.

·       Accurate and reliable results to make decision.

·       It is a non-destructive testing technique. You wouldn’t have to chip or crack the material under testing. Hence, it reduces damage on the materials.  

There are countless advantages of using eddy current testing methods for various industrial operations. However, make sure you invest in premium quality equipment from a reliable supplier to get effective results.

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
