摘　　要：压力容器设备中法兰与筒体、法兰与接管连接处的C类焊缝和封头端部、筒体上马鞍形的D类焊缝是最为不规则的且施焊工艺最为复杂的焊缝。着重讨论C、D类焊缝的T形接头形式和角接接头形式的焊接工艺,尤其是对施焊难度高的D类焊缝的接头坡口形式、优缺点以及适用场合进行了分析。通过分析得出其合理的T型接头形式和施焊方法,为压力容器中此类焊缝的焊接提供参考作用。In pressure vessels,C and D seam which are located at the joint of flange,tube-shape object,jointed tube,and head of pressure vessels separately are the most eomplex seams.In this paper,it analyzes welding process method and joint shape of C and D seam.Especially for joint shape and applicable situation of troublesome D seam.The reasonable joint shape and welding process are obtained ,which is to provide better reference for the welding technology of this seam.
