The relation was investigated, between nondestructive tests (electro resistance method and ultrasonic method) and destructive tests (shear strength test and ram tensile strength test), with explosively bonded steel, SUS316L (6.5mm)+ASTMA204 (22mm), which contains unbonded area. The electro resistance method, the JIS ultrasonic method by the reference block and Cross's ultrasonic method by the amplitude difference provide quantitative results, while the JPI ultrasonic method by the damping of multiple reflection produces only qualitative results and requires some delicate manipulations. The indicate voltage of electro resistance method represents the shear strength, and the amplitude difference of Cross's ultrasonic method corresponds to the shear strength and ram tensile strength. For the nondestructive tests at the boundary between completely bonded area and unbonded area, the position of the probe has significant influence on the test results.
