| Abstract: | In drilling exploration and well drilling Industry, the drilling pipe and drill collar are key apparatus. These apparatus work in a stern circumstances and undergo high stress for longterm. Therefore, fatigue cracks will occur easily and it is possible to result in severe accident. In this paper, ultrasonic testing method for these apparatus is presented and the special cantact focussing probe is developed. |
