Eddy current thermography [1-5] consists in using electromagnetic induction to create heat flow in the material and record its thermal response using an infrared camera. Defect detection is based on the changes of the thermal distribution. It is an efficient and precise method for detecting subsurface defect in metallic materials and can be deployed either in the form of pulses or amplitude modulations [3, 4]. This paper describes simulation works using Pulsed Eddy Current Thermography for… CONTINUE READING
