transfer Key type weldingjoint;defect 近几年,T型、K型、Y型(以下简称TKY 1检测对象 型)管状焊接接头超声波检测在国内广泛应用于 船舶制造、海上和陆地钢结构制造,这种检测工艺 TKY型管状焊接接头与平板焊缝的不同之处 RP2X 在美国、加拿大等国家应用较多,美标API 在于前者超声波检验的扫查面为不同曲率的曲面...
TKY管节点焊缝相控阵评价方法研究摘要TKY管节点结构由于其优越的结构性能和使用性能,在钢结构和海洋平台中有着广泛的应用,但由于其复杂的空间结构,管管连接焊缝的检测在目前工程实际检测中存在着诸多的问题,如采用横波的方法检测时,缺陷的定位是使用手工作图的方法,存在缺陷定位步骤复杂、效率低、准确性差和人为因素影响...
2.在以往海洋工程平台导管架项目,tky节点为单面焊,导管架项目的tky节点,标准叫法为tubular joint/branch connection,不同管径的钢管相互交叉焊接时,因管径不同、连接的二面角不同、多段钢管相互连接焊接时,会呈现出t型、y型或k型形状,故通俗称之为tky节点。涉及到的导管架tky节点,坡口形式由专用的坡口机设备切割成...
