Nondestructive Testing (NDT)

Nondestructive testing (NDT)Nondestructive testing methods include a wide group of analysis techniques to evaluate the properties of a material, component or system without causing damage. They are important for the assessment of fabrication quality and for the detection of early damage through alteration in microstructures leading to premature failure. They allow the investigator to carry out examinations without invading the integrity of the engineering component under investigation. In this chapter we will present the following NDT methods: dye penetrant, magnetic particles inspection, eddy currents, radiography, ultrasonics and acoustic emission.
