Computer Technologies and X-Ray Flaw Detection of Welds

摘要

Quality of X-ray films interpretation by a flaw detector operator always bears rather a subjective character. Such factors, as qualification level of a flaw detector operator, their state of health, fatigue, sharpness of sight, limited evaluation capability, and also quality of the X-ray images (fuzzy boundaries, bad visibility, weak expressiveness of the defect image in relation to background etc.) render their negative effect. Welds quality assessment also requires execution of defined complex of metrological and calculation-analytical measures, which are hard to carry out due to absence of tools for realization of such operations. It is obvious, that the quality of flaw detection of welds depends to a large extent upon qualification and skill level of the experts in the given area. Proposed is method of implementation of computer technologies in area of X-ray flaw detection of welds, as a way to solve each of the above-stated problems.
