摘要：

This paper presents the development of a testing technique for measuring the angle of inclination and depth of surface-breaking inclined cracks in simple geometry components using a manual ultrasonic time of flight diffraction system. The testing technique in this work can be useful in risk based test planning for simple geometry components such as pipelines and boiler headers.
