由电力建设总局召开的焊缝无损检测技术研究会于4月17日～21日在湖南长沙召开,来自全国25个省、市、自治区的电业部门共60名代表参加了会议。这次会议讨论了管道焊缝超声波检验的方法和可靠性,对探伤起始灵敏度和判废标准作了重点的研究。一致认为,在管道焊缝检验中,超声波探伤是主要的检验手段之一。由于超声波小探头的制作成功,对小径厚壁管焊缝的检验也是行之有效的检验手段。射线检验是我部系统比较成熟的检验方法。会议对提高射线探伤焊接缺陷检出率的技术措施作了各方面的探讨。射源的种类增多了;射源探伤的面更广了,在电站焊接检验中发挥了重要作用。
A total of 60 delegates from the electricity sector in 25 provinces, cities and autonomous regions across the country attended the conference on April 17-21, held in Changsha, Hunan Province, from April 17 to 21, held by the Electric Power Construction Bureau. The meeting discussed the method and reliability of ultrasonic inspection of pipe welds, focusing on the initial sensitivity of testing and the standards of sentence-making and rejecting. It was agreed that ultrasonic flaw detection was one of the main test methods in pipe weld inspection. Due to the successful production of small ultrasonic probe, the test of small diameter thick-walled pipe weld is also an effective test means. Ray inspection is a more mature system of inspection methods. Meeting to improve the detection of ray flaw detection of technical measures made in all aspects of the discussion. There are more types of sources; the flaw of the source detection is broader, which has played an important role in the welding inspection of power stations.
