Application of Induction Thermography for Detection of Near Surface Defects in Steel Products
(2020)
Steel is one of the most important materials used in modern maritime vehicles. Modern production techniques make steel grades available that fulfill current requirements of these safety critical applications regarding their mechanical properties and their processing. However, constantly increasing demands on the quality and cost-effectiveness of steel products must be matched by the development and implementation of efficient testing methods.
This paper explores the possibility of using induction thermography as a non-destructive testing method for this measurement task. Therefore multiple experiments were conducted using representative pieces of steel in which defined artificial defects were incorporated through milling.
