Analysis the Results of TOFD Inspection in Butt Joint Welds

Abstract:

In the application of the TOFD inspection method, the analysis of test results is the focus and aporia of the study. TOFD image analysis include: analysis of defect size, location analysis and defect map features. In order to increase people's understanding of the TOFD technique, given butt joint welds TOFD and RT detect. The paper introduces basic process of defect using the TOFD method, describes method of quantitative orientation of the defect in detail, analyzes the localization and quantification of defects in detection. Determine the qualitative of defects by Ray photographs and analyze the characteristics of the defects of this nature in the TOFD image.
