Advancement and Trends in Non-Destructive Testing Methodology

  Did you know we are currently in the fourth industrial revolution since the start of the 21st century? This time, the industrial transition features processes and technologies that promote the use of automation, enhanced connectivity, process optimisation measures, and better data management to increase productivity, save time, and minimise costs.  Non-destructive testing  technology is one of the developments that continue to thrive with the growing need to reduce human involvement in maintaining, troubleshooting, and monitoring materials.   Compared to traditional testing methods, non-destructive testing is non-invasive, faster, and more reliable in identifying a material’s structure, quality, component, or integrity. Plus, it does not require taking samples for testing in a lab, so it does not interfere with the product’s or material’s final use. As such, it delivers benefits like cost-effectiveness and quality control. Below are some of the most current trends and advancement

Applications of Eddy Current Testing in Non-Destructive Testing

  One of the most trusted methods in non-destructive testing is the  eddy current , which is based on the principle of electromagnetism to find flaws in conductive materials. This makes it useful for many purposes, like measuring coating and material thickness, flaw detection, establishing conditions for heat treatments of specific materials, and material identification. Probes, devices, and other relevant instruments are available to make it easier to use in any application, especially in characterising and detecting sub-surface and surface flaws.     How does it work in NDT?   A specially designed coil is involved in eddy current testing, and it is placed near the test surface to be energised by an alternating current. It creates a magnetic field that links to the test part and generates eddy currents in its vicinity. Changes in various phases and the magnitude of the currents are then monitored using a receiver coil. Alternatively, you can measure variations in the altern

Portable Hardness Testing for Effective Quality Control: Techniques and Applications

  The purpose of hardness testing is to ascertain a material's strength, heat treatment, and wear properties. It's usually carried out on metals to confirm their characteristics and fitness for specific applications. Traditionally, the test could only be conducted with a benchtop system. However, advancements in technology have led to the development of portable hardness testing methods that allow testing on different scales, depending on the applied force and indenter's shape, with Brinell and Rockwell being the most frequently used. Let’s talk about the different methods and their applications.   Leeb testing technique   Leeb hardness is the indenter’s relative velocity before and after impact. A  portable hardness testing  device that uses this testing technique will bounce the indenter off the test piece surface with a spring-loaded mechanism. One of the benefits of this system is its portability, so you can bring the device to the element instead of taking a sa
