摘　　要：火焰筒安装边与定位块的连接采用氩弧焊,其焊缝结构类型为搭接角焊缝。对火焰筒安装边定位块焊缝分别进行射线检查和金相解剖,比较分析了两种方法的检测结果,阐述了射线检测对该类焊缝结构的检出性。Argon-arc weld is adopted to connect liner-comb and its locking block,and the weld configuration is lap fillet weld.Radiographic inspection and metallurgical cut-up evaluation are conducted on the weld respectively,after comparing the inspection results of both methods,the testability of radiographic inspection of this type of weld is demonstrated.
