Infrared Thermography: A Tool for Defect Identification

In this work, the potential of infrared thermography (IRT) to assess moisture related phenomenon was tested. Infrared thermography, due to its non-contact character that allows for quick surface mapping, represents a powerful tool for non-destructive testing (NDT) of materials and structures. As Infrared thermography is still not completely exploited, and traditional methods are still employed. Due to the ambiguity in the analysis by using traditional methods of non-destructive testing this method emerges as an easy and quick method. So, in this paper, different areas were taken for inspection on the college campus and at the same location traditional method of NDT was also performed and the results are compared. The same has also been performed by casting the concrete cube having porous pipes inserted into a cube and the source of leakages was detected. At last the cost required by the conventional method and IRT was compared and found that the cost required by IRT was much economical than convention method Thus, anomalies were found during a short-elapsed time. The infrared thermography is useful in detecting invisible defects non-destructively, extensively and safely.
