This paper focuses on the grope of reflection principle of various k inds of groove shape flaws under the supersonic force, tries to figure out a ref erenced groove shape applicable to supersonic flaw detection of single face butt weld, points out the fundamental flaws of measured single face butt weld especi ally the errors likely to happen during the measurement of crack flaws. Through the experimental measurement, the rational formula for the groove shape has been tested and the conditions and applicable...
