X-ray and back-wall echo ultrasonic examination of wrought iron building structures

Abstract

The wrought iron building structures constituting part of the architectural heritage, e. g. handrails, gate hinges, columns, arch ties and wall ties represent incorporeal value, but operate as load bearing structures as well. There are few information on their mechanical properties and quality. Due to the inhomogeneity of the material of wrought iron building structures generated during the production, the known metal testing methods, as the tensile and hardness tests or metallographic examination, are not enough to survey the properties of such structures in depth. For the further and more accurate examinations, the application of X-ray and back-wall echo ultrasonic tests are essential. The goal of our paper is the presentation of the application of the examinations used extensively in the machine industry for the testing of wrought iron building structures.
