What are advanced NDT techniques?

Advanced NDT (Non-Destructive Testing) techniques refer to specialized methods used to evaluate the properties and integrity of materials, components, or structures without causing damage. These techniques go beyond traditional NDT methods like ultrasonic, radiography, or magnetic particle testing, and include approaches such as phased array ultrasonic testing (PAUT), time of flight diffraction (TOFD), computed radiography, and digital radiography. Advanced NDT is often used in industries like aerospace, oil and gas, and power generation to detect flaws, corrosion, or structural weaknesses with higher accuracy and efficiency. These methods help ensure safety, reliability, and compliance with industry standards.
