Non-Destructive Testing Techniques: A General Review of Methods

This paper provides a general review of the NDT techniques, including what principle these methods work,their advantages, disadvantages, and limitations. NDT techniques are used worldwide in various industrieslike construction, oil and gas, and aerospace to evaluate the conditions of the structure and materials usedin that structure without causing any damage to the structure. The methods covered in this paper aregenerally used in the construction industry, including tests for surface hardness and strength like reboundhammer, ultrasonic pulse velocity, core test, CAPO test, and some tests for corrosion assessment like halfcell potentiometer and carbonation test. A review of this paper aims to provide a comprehensive overviewof the various NDT methods used in the construction industry and their role in ensuring the quality, safety,and reliability of structures and materials.
