| Abstract: | The shortcomings of existing NDT technique in the inspection of the surface crackle on cold-drawn bearing steel bars of small diameter are discussed. Based on the principle of surface testing with the ultrasonic wave, a new inspecting method is proposed. A line-focus probe with a single long wafer has been designed to improve the efficiency and a microcomputer-based automatic system is used to perform intelligent control and to improve the reliability. |
