An experimental study of defect determination using pulsed thermal non-destructive testing

The application of Infrared Thermography (IRT) as passive method is widely used and accepted by industry. However, IRT technology as transient or active method is considerably new for industry in term of measuring defect in Non-Destructive Testing (NDT) activities. The primary objective of this paper is to present an experimental study of determination of artificial defect in material using active thermography, in particular to pulsed thermal NDT (TNDT). Both terminology and basic principles in TNDT will be discussed. It is shown that several factors may influences TNDT results. As a conclusion, this study has confirmed the ability and potential of TNDT as a technique for defect determination in material.
