Abstract

NDTs are widely used in manufacturing sector for the assessment of the weldment before sending it to destructive testing (DT) techniques. The main purpose of NDT is to detect the surface and sub- surface discontinuities/ defects, presence of which may adversely affect the mechanical properties of weldment. NDT does not affect the basic structure and mechanical properties of the component being inspected in any way. In this way this technique saves a lot and resources in terms of time and money. The weldment may have different types of defects such as porosity, cracks, undercutting, lack of fusion etc. These defects can be easily determined without damaging the work piece and necessary remedies can be taken to alleviate the severity of the defect.
