6 Characteristics To Know While Using Eddy Current Measuring Techniques

 Eddy current is a type of electric current that moves quickly in a circular motion, often producing a downward spiraling action in bodies that conduct electricity and heat. Since these actions remind one of a whirlpools in a small, narrow river, hence their name.

Commercial enterprises mostly use non-destructive approaches to evaluate metals. Eddy current testing is a popular non-destructive method to check electrically conductive goods.

It is good to know the characteristics of Eddy current testing, if you want to use it to evaluate the materials or samples non-destructively.

1-   Analyse metals without physical contact

When determining the electrical conductivity in a metal, learn that analysis with eddy currents does not involve any physical contact between the metal specimen and the sensor.

2-   Can identify cracks

The interplay between a magnetic field source and a metal specimen is what introduces eddy current in the metal sample. When researchers observe changes in the current movement inside the eddy current flow, then it could indicate little cracks within the metal specimen.

3-   Offer rapid testing at 150 m/s

Eddy current testing procedures are not only consent to, but also approve of swift testing, even in demanding working conditions where different non-destructive strategies can't be adopted.

4-   Have prompt and automated examinations

Eddy current testing technique has control systems and information technologies that make it exceptionally quick at analysing partially completed goods like wiring, rods, cylinders, pipes, metal profiles in production lines, etc.

5-   Give immediate test results

Eddy current testing methods give instant outcomes. On the other hand, investigation with liquid penetrant testing or optical inspection procedures takes a lot of time.

6-   Discover cracks in both ferromagnetic and non-ferromagnetic goods

Eddy current testing can ferret out cracks in a wide variety of metal products (ferromagnetic or non-ferromagnetic). The alternative, non-destructive approaches like the magnetic particle procedure are restricted to ferromagnetic metals.

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 tr...

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 th...

Ultrasonic Testing - Applications and Advantages of Ultrasonic NDT in Industry

Ultrasonic testing is a non-destructive testing method that is used commonly for -        Detecting cracks, defects and faults in a test piece; -        Measuring the dimensions of a test piece; -        Understanding the nature or character of a material; How is the test carried out? The testing unit or system consists of a receiver, transducer, and a display unit. The receiver or pulse is the unit that produces electrical pulses. The transducer then produces ultrasonic energy in high frequency. This sound energy or wave passes through the test piece. If the material has no-fault, it will behave as a standard piece – however, when there is a crack, fault, or break in between, the wave is intercepted by this fault line from where the wave reflects. This reflected wave or echo is then converted by the transducer into an electrical signal. This electrical signal gets displayed on the s...
