钢熔化焊T形接头未焊透缺陷深度超声波检测探头及试块方法

Steel T Shape Welding Joint Without Weld Depth of Ultrasonic Flaw Detection Probe and Test Block Method

钢闸门、钢闸门支臂、坝顶门机和厂房桥机箱形梁结构等存在大量钢熔化焊T形接头未焊透缺陷,为了消除按照现有超声检测标准存在的分歧,通过大量试验,得出适合钢熔化焊T形接头未焊透深度检测的探头、试块和方法,使超声波检测的准确性、客观性、认同度大大提高,能够较好地消除分歧,并在实践中取得较好的检测效果。

There is a lot of steel fusion welding T-joint in steel gates,steel gate arm,crest door and plant box beam bridge structure.There are some differences between the test results in accordance with existing standards frequently.We carry a lot of experiments in order to eliminate differences in this paper.We developed a suitable fusion welded steel T-joint width detection of incomplete penetration probe,test block and methods.The accuracy,objectivity,and identification degree of detection were greatly improved.The divergence were better eliminated.There were better detection results in practice.
