摘要
介绍了为解决奥氏体不锈钢焊缝的超声检测技术而做的一系列研究工作,研制了专用于奥氏体不锈铜焊缝的超声检测的低频宽带窄脉冲纵波斜探头和标准试块、对比试块,并且在焊接试板上进行了测试试验解剖了缺陷试板。在工程实践中也进行了应用,取得了良好的效果。
This article describes a series of researches made to solve problems in the ultrasonic inspection of austenic stainless steel weld seam. We have developed the low-frequency bandwidth narrow pulse vertical wave slope probe, standard sample and contrast sample,which are specifically used in ultrasonic inspection of austenic stainless steel weld seam;we have tested them on weld-joint testing boards and dissected defective test boards;we have also used them in engineering practice and achieved good results.
