黄冈公铁两用长江大桥采用了平行四边形截面整体节点焊缝形式。根据焊缝受力状态确定了每条焊缝的具体检测要求，针对8种不同的特殊角接接头拟定了具有针对性的超声检测方法，分别采用直探头和斜探头对焊缝进行检测。实践证明，检测结果准确可靠，能够满足工艺规范的要求。

The Huang gang Yangtze River railway-highway combined bridge adopted parallelogram section integral node, and the test details required by each welding line are conformed to its stress condition. The specific UT methods are drawn up on the basis of eight different special angle welding joints, and the normal probe and angle probe are used separately for the UT test. The accuracy of the test results was proven by practice. The test scheme meets the requirements of the technological specification.
