| Dr. Obdulia Ley Presents Thermography Technique
Dr. Obdulia Ley, a member of the MISTRAS, Research, Contracts & Application (RC&A) group, has hit the road speaking at several ASNT and SAMPE conferences about “Line-Scanning Thermography: A Solution for Large Area Non-Destructive/Non-Contact Inspection”.
Dr. Ley spoke about the innovative thermography-based real-time NDT method capable of wide area inspection, known as Line-Scanning Thermography (LST). This technique has successfully been applied to determine the thickness of metallic plates and to assess tube thinning. Dr. Ley will present MISTRAS’ efforts towards the applications of LST for the analysis of laminate composites, along with having LST protocols on hand to show the detection of sub-surface disbonds (delamination) in composite sandwich parts and wind turbine blades. The thermal images acquired using LST will be compared with ultrasonic C-scans, along with the fundamentals of IR imaging and the limitations of thermography for NDT inspection being discussed. Dr. Ley will present her findings on the relationships between measured surface temperature profiles and the severity of the defect, as well as the effect of the scanning parameters such as heat deposition intensity, the scanning speed, the face-sheet thickness, and the thermo-physical parameters of the layer materials. |
