| Abstract: | An automated radiographic NDT system for weld inspection is developed. The entire system consists of two major components: weld extraction and flaw detection. Welds are first extracted from digitized radiographic images. The extracted welds are then processed by flaw detection algorithms to determine their qualities. This paper describes the weld extraction methodology, which forms the first part of the system. An example is used to illustrate the working of the methodology. The methodology is concluded to be effective for weld extraction after being successfully tested with 25 images. |
