摘要
简述小口径薄壁管专用探头的研制原理,制作了带人工缺陷的对比试样和含多种自然缺陷的模拟试样,依据标准试块为判断基准,对对比试样和模拟试样中的人工缺陷和自然缺陷进行探测,获得了小口径薄壁管中不同缺陷的不同回波响应情况,并分析了检测的可行性,尝试得出小口径薄壁管超声波检测的一般原则。
The manufacture principle of special probe for thin wall and small diameter tube was described, some reference block with artificial defects and natural defects were made, which was inspected by the special probe. The result of the experiments showed that the echoes were different for different defects. The feasibility of ultrasonic testing of thin wall and small diameter tube was analyzed. Finally, a general ultrasonic testing technique for thin wall and small diameter tube was obtained by trial-and-error.
