In this study, it aims to allow complicated shapes cracks such as stress corrosion cracking can be detected by the ultrasonic flaw detection method. Test pieces were prepared two kinds of cracks inclined with cracks branched. The experiment was carried out by water immersion one probe method.We was examined that the difference in reflection intensity depending on the angle of the branch and differences due to cracks shape from the interference of the reflected waves. It was further devised a method for determining the angle of the discriminant and cracks shape.
