Non-destructive testing (NDT) is a testing and analysis technique used to evaluate the properties, acceptability, or fitness of a material, component, structure, or system without permanently affecting the item under test.
Specifically, this procedure may include:
· Detect internal or external defects
· Determine structure, composition, or material properties
· Measure geometric characteristics
Depending on the extent of analysis carried out on the outcome of the inspection (Go/No-Go, Accept/Reject, quantitative assessment, life assessment, remaining life, fitness-for-service, etc) the other terms commonly used to describe this technology are Non-Destructive Examination/Evaluation (NDE), and Non-Destructive Inspection (NDI). It supplements destructive testing, which is carried out typically to determine the strength of structures by methods such as breaking, peeling, etc – which is both time consuming and wasteful.
As no harm occurs to the items under test during NDT, it is a very valuable technique used for product evaluation, research and problem solving which can save both time and money. NDT is used widely in all areas of engineering, aerospace, defense, oil & gas, power generation, automotive, medicine and even art and cultural heritage preservation. NDT could employ any (or a combination of) techniques including Visual Inspection, Eddy Current, Fluorescent Penetrant, Flux Leakage, Magnetic Particle, Radiographic, Tap Testing, Thermography, Ultrasonics and several more – all based on different physics principles.
A multidisciplinary profession cutting across domains where physics, chemistry, materials science, mechanics, electronics instrumentation, computer science, etc. synergize in several ways to realize the end objectives. NDT can and should be used in all phases, from raw materials to product's design and manufacturing process (including materials selection, research and development, quality assurance and production) and while in service till end-of-life; leading to being termed as a cradle-to-grave technology!

Ultrasonic Technologies is pervasive now-a-days. Every day, we encounter the magic of Ultrasonics while, reversing your car, parking, using cell phones, using a fingerprint biometrics, …….and many more.
Did you know that Ultrasonics is also a part of your daily routine as a fluid level or flow sensor in your water or gas pipes?
Ultrasonic sensor technology also keeps us healthy through biomedical imaging and diagnostics, destroys your kidney stones, keeps us safe via nondestructive testing-based quality control and through in-service inspection, keep our infrastructure operating beyond its design life by continuous structural assessment.
Recently, low-cost Ultrasonic Technologies are also becoming relevant in the COVID world by providing touchless communication, for augment and virtual reality applications and in everyday robots, all of that redefines our lifestyles.
AZERIRI is a deep-research deep-tech startup company, backed by 100 years of international professional experience of the founding team, that will help make the ultrasonic technologies more relevant, more affordable, more sustainable by focusing on the state-of-the-art transducers that will be the key ingredient to any ultrasonic system. Incubated by the best academic startup eco-system in India, located in the IIT Madras Research Park, with support from the #1 ranked university in India, AZERIRI aspires to disrupt the supply chain of ultrasonic applications and products.
Best wishes to AZERIRI for achieving its vision and its goal of becoming a gamechanger in the ultrasound world.
