Welding. Methods for assessing imperfections in metallic structures Ingestion-build-84997 7 Dual circuits/diverse routesPD CEN TR 15235 provides guidance on the selection and application of methods for assessing the significance of imperfections in all types of structures and components. The guidance is primarily tailored to welded structures and components in steel or aluminium alloys. The present Technical Report gives guidance to the application of BS 7910. Some of the methods may also be applied for other types of metals and for non welded structures and components.
