Relation between defect depth and standard thermal contrast on the steel surface in pulsed thermography
The work is devoted to experimental determination of the diameter and the depth of simulated subsurface defects in steel using pulse thermography (PT). The simulated defects had a form of flat-bottom holes of diameter 1.0-5.0 mm and depth 0.3–1.5 mm. The defect diameter has been reconstructed on the basic of analysis of the rate of temperature decrease on the surface of tested specimen after it...
متن کاملQuantitative Subsurface Defect Evaluation by Pulsed Phase Thermography : Depth Retrieval with the Phase
Pulsed Phase Thermography (PPT) is a NonDestructive Testing and Evaluation (NDT&E) technique based on the Fourier Transform that can be thought as being the link between Pulsed Thermography, for which data acquisition is fast and simple; and Lock-In thermography, for which depth retrieval is straightforward. A new depth inversion technique using the phase obtained by PPT is proposed. The techni...
متن کاملEarly detection of thermal contrast in pulsed stimulated thermography
Stimulated Infrared Thermography (TIS) is a fast and global method for NonDestructive Evaluation (NDE). Among the recently emerging NDE methods, it is probably the less intrusive one since it really needs no contact at all with the tested structure. A new inversion technique, using an early detection of the contrast, is presented to demonstrate how it recovers the depth of the defects with accu...
متن کامل3D Thermal Imaging: Fusion of Thermography and Depth Cameras
This work presents an approach to automatically create 3D thermal models using multi-perspective measurements with a multimodal camera system consisting of a thermal camera and a depth camera. Additional attributes such as color can also be added to the model. The paper centers its attention on the geometrical calibration of the cameras and the validation of the results. The design of an adequa...
متن کاملStress Measurement Using Pulsed Eddy Current Thermography
This paper reports a noncontact inspection method, using Pulsed Eddy Current (PEC) stimulated thermography, for the evaluation of the anisotropic dependency of electrical conductivity of steel exposed to tensile stress. This method combines microscope lens based thermography with PEC using a rectangular excitation coil, giving directional excitation, to infer the electromagnetic properties vari...
