Thermal Nondestructive Testing: Development of Conventional Directions and New Trends (A Review)
V. P. Vavilov
Abstract
Abstract In recent years, thermal testing has been a rapidly developing field of nondestructive testing due to the development of composite materials, testing of which by conventional methods is difficult. Undoubted progress has been made in the development and commercialization of thermal imagers that form the basis of thermal flaw detectors. Starting from earlier reviews, the author tried to summarize the achievements of recent years both in the methodology of testing and processing of temperature information and in the development of modern thermal flaw detectors and their fields of application. The review includes domestic achievements in the field of thermal testing and numerous foreign studies, thanks to which thermal testing is considered as one of the main methods for nondestructive testing of certain classes of materials and structures.
