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

An ultrasonic thickness gaugeis one of the most popular industrial non-destructive testing (NDT) tools. It measuresthe thickness of material when only one side is accessible. It functions non-destructively, using ultrasonic waves to detect changes in the material. Before getting in the detail ofdifferent ways to use an ultrasonic thickness gauge , it is necessary to understand how these gauges work. A dual-element transducer consists of two crystals. In this gauge, the ultrasonic waves sent from one crystal create a 'V' pattern by hitting the material's back wall and reaching the other crystal. The gauge measures the time taken for the ultrasonic pulse to travel to and forth. Taking variables like the speed of the pulse, material, and any potential acoustic barriers, it calculates the wall's thickness. A single element transducer uses only one crystal to send and receive the pulse. Here are the three ways to use an ultrasonic thickness gauge:         i    For coat

  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 change

A coating thickness gauge, also known as a paint thickness gauge is an important quality assurance tool for galvanizing, anodizing and applying a zinc coating to all kinds of metallic surfaces. Simultaneously, this instrument is also used to measure the overall paint thickness and uniformity on the products like cars, where its role is to reveal the repainted spots, check the hidden damages, and expose all the undisclosed accidents. Using the information provided by a paint thickness gauge, one can determine the actual condition and the value of a used car. A paint thickness gauge is used as an intelligent and precise tool that could measure the thickness of the paint coating or plating on a surface and provide accurate results. These surfaces could be metallic or non-metallic. The use of this tool is extensively widespread on both these surfaces. One may also explore different kinds of gauges if they want to measure the thickness on other kinds of surfaces and materials. A paint t

  Hardness tests assess the resistance a raw material subject to permanent deformation by penetration of another hard material. It evaluates the material properties, such as strength, ductility and provide useful information to the users whether a material or material treatment is suitable for the purpose required. From a manufacturing or maintenance viewpoint, hardness is of great importance given the fact that resistance to deterioration through the medium of friction or erosion (by water vapour, greasy liquid, and water) escalate with hardness. Hardness is generally calculated using three fundamental categories of hardness estimations, scratch, indentation, and rebound. Inside each hardness estimation type, there are customized measurement scales. Indentation hardness calculates the resistance of a specimen (of a raw material) to permanent material distortion owing to a continuous compression load from a sharpened item. In a Rockwell hardness test , the hardness of the raw m

  While testing the material's, hardness will not give any direct measurement on the performance-related characteristics. It provides important clues about the wear resistance, strength, and other properties. The  Rockwell hardness test   method is one of the most common and general methods used for testing the bulk hardness of metals and polymers substances and materials. The method is quite simple to use and is also quite affordable for measuring the properties of materials directly. The Rockwell scale is based on the indentation hardness (the hardness to deformation) of a material. The test involves measurement of the penetration depth of a given intender under a significant/large load and a minor load. The depth of the indentation measured is converted to a value on the Rockwell Hardness Scale. The Rockwell Conversion Charts are used to find out the corresponding hardness and its measurement. Benefits of the Rockwell Hardness Test Rockwell hardness test  is a common and aff

The underlying principle in most generators and electric motors would be magnetism. This is the force that is responsible for managing a wide range of eddy current instruments too. Eddy current is useful because it can cover large surface areas within a short time. It is identified as one of the quickest ways of measuring thicknesses, and even the impact heat has on various equipment. Also,  eddy current testing doesn’t need any coupling liquids. This makes it easy to use eddy current for checking conductivity and hardness in metals. However, it is important to note that the use of eddy current testing   is limited to materials that can conduct electric energy. Thus, this form of testing cannot be used on liquids.  In some interesting situations, ultrasonic testing is executed with the help of an eddy current. Both of these methods complement one another. The ability of ultrasonic waves to penetrate deep surfaces, and the quick surface testing property of eddy currents - makes it ea
