    NDT techniques have been used for many centuries to evaluate the quality of materials and structures. One of the earliest known examples of NDT was the use of sound to evaluate the quality of iron and steel. In ancient times, blacksmiths would strike a piece of metal with a hammer and listen to the sound it made to determine its quality. If the metal had a clear, ringing sound, it was considered to be of high quality. This method of testing, known as “ring testing,” was used to identify defects and impurities in the metal.

    In the 19th century, NDT techniques began to evolve with the development of new technologies, such as X-ray imaging and ultrasonic testing. These methods allowed engineers and technicians to evaluate the properties of materials and structures more precisely and accurately than ever before.

    Today, NDT has advanced significantly and employs a wide range of sophisticated techniques and equipment to evaluate the properties of materials, components, and systems. NDT is used in a wide range of industries, including aerospace, automotive, construction, energy, and manufacturing, to ensure the quality, safety, and reliability of products and structures.
