A Study Of the Defect Location Using Single-disc and Double-direction Incline Probe Testing

With the wide use of ultrasonic testing technique in industry and strict requirement for product quality inspection,various specialized new UT probes are invented continuously.Among them single-disc and double-direction incline probe to some components such as internal-combustion engine crank and oil drilling are applied.However,its special structure made it defficult to locate the defect.This paper discusses and analyses this problem.The experiment results show that the obtained calculation formula is effevtive.
