MODELING STEADY-STATE THERMAL DEFECTOSCOPY OF STEEL SOLIDS USING TWO SIDE TESTING

ABSTRACT
In this paper, performing the thermal defectoscopy of a steel solid body by applying the thermovision camera, finite element method and method of filtering experimental data is proposed and implemented. Defect thickness, depth and size are analysed by defined temperature reference levels and simplified methodology. The thermal image processing is based on the proposed method. The applicability of this method can be confirmed by comparing analysis of obtained results with already known methods. The conducted experiment indicates that contactless method is efficient in the defects detection of thin non-complex prismatic parts.
