The Infrared-Thermography Technique is widely used for nondestructive evaluation (NDE) of structures due to its convenience. Particularly, various techniques have been tried to detect imperfections such as surface defects and welding defects of steel structures. This paper is a part of a study to detect defects in weld zone in steel structures using Infrared Thermography techniques. Finally, defects were detected by comparing infrared thermal image and surface temperature data of defected area with healthy area.
