Radiographic inspection is a well-established testing method to detect welding defects. However, interpretation of radiographic films is a difficult task. The reliability of such interpretation and the expense of training suitable experts the efforts being made towards automation in this field. In this paper, we describe an automatic detection system to recognize welding defects in radiographic images. Image processing techniques, including noise reduction, contrast enhancement, thresholding and labelling, were implemented to help in the recognition of weld regions and the detection of welding defects. The results underline the efficiency of the techniques used in the work.
