AWS- WHC1.14 Welding Inspection and Nondestructive Examination


Chapter 14 from the Welding Handbook, Ninth Edition, Volume 1, “Welding Science and Technology,” has been selected by the AWS Product Development Committee as a service to industry professionals. WHC1.14 Welding Inspection and Nondestructive Examination addresses the inspection and nondestructive examination of joints produced by welding and related processes. The term inspection denotes an all-encompassing quality control activity that includes numerous steps applied at different stages during a component’s fabrication and service life. Thus, this term describes activities that are performed not only at the time of manufacture but also after the component has been subjected to service. While the types of discontinuities revealed during these varying stages may differ, the basic principles governing the inspection activity are essentially the same. Consequently, the majority of the information presented in this chapter is applicable to new manufacture, repair operations, or the evaluation of components that have already been subjected to their intended service conditions.
