摘要
大型变压器油箱焊缝缺陷的无损检测李全禄（陕西师范大学应用声学研究所，西安７１００６２；作者，男，４５岁，讲师）大型电力变压器的油箱（约２０ｍ藏）的焊缝要求焊接质量很高，以防变压器在运行期间渗漏油、汽而引发事故．常用到的探测焊缝缺陷（孔、缝）的方法有：...
The three DNT methods: soap bubble, ammonia and acoustic method of welding seams on large-scale power transformer oil tanks and their experments are briefly reported The, testing results of the three methods are analyzed and compared
