摘　　要：作为不锈钢的替代材料,改良型9Cr1Mo钢管T91(9Cr1MoNbVN)在电站锅炉行业的应用越来越多。介绍了日本开发的钢管液相扩散焊技术及其在T91钢管焊接方面的应用情况。与现行T91钢管的弧焊工艺相比,工艺简单的液相扩散焊技术具有无需预热、无需监控层间温度、自动化程度高、生产率高、回火处理容易等优点。The stel tube of T91 is widely used in steam boiler because it is capable of replacing austenitic stainless steels.Both the transient liquid phase （TLP）bonding technique for steel pipe and the application of TLP bonding to T91 in Japan are introduced.Compared with traditional are welding,the TLP bonding technique for T91 has some advantages,such as high level automation,high efficiency,convenience of tempering while the preheating,and the interpass temperature monitoring met need.
