Abstract
This paper describes the γ-ray flaw detection of welds in steam turbine rotor, the design of radiographic mode, selection of radioisotope source and some test results for detectability. Practical application shows that utilizing ~(192)Ir for rotor welds inspection has technical and economical values.
