Ensaios não destrutivos: Fundamentos e Aplicações

Abstract

Non-destructive testing (NDT) are techniques used in the inspection of materials and equipment without damaging them, being performed on the stages of manufacture, construction, installation and maintenance. These techniques are one of the main tools of quality control of materials and products, helping to ensure quality, reduce costs and increase reliability of inspection. Various techniques can be applied to detect and size discontinuities on the surface and in the interior of a material. However, most of the time a single test is not 100% efficient, either through technological restriction or even human factors. In this way the use of two or more means are advised to obtain a better result. This is an important issue for companies holding of petrochemical segments, steel, aerospace, nuclear, among others, which require a high degree of reliability. This work will address the main non-destructive testing techniques, because the constant search for improvements to meet the requirements of the industry attracts significant investments in research on technology in inspection equipment, this form the objective of this work is to pass to the reader the knowledge in the academic and technical standards within the subject studied.
