Non-destructive testing, or NDT, is an industry analysis and testing method used to evaluate the properties of different structures, materials, or components as well as identifying and assessing defects while maintaining the integrity of the sample subject. Some types of defects commonly occurring in industry are stress cracks, weld defects, slag inclusions, and corrosion.
Non-destructive testing plays an important role in not only the life of finished products, but also throughout the stages of manufacturing with the end result being both cost and time-saving.
The choice of an individual method depends on several factors but most notably types of inspections performed, cost investment, what do the testing materials/components consist of, and time and sensitivity constraints.
