摘要
目前国际上考虑高温下焊接结构特点的评定规范尚不多见，我国在此领域亦还属空白。为此，本文在评述国际上高温结构的评定规范的基础上，着重介绍了Ｒ５ 卷６ 对异种焊接头的评定方法，包括评定程序的步骤、参数的选取和实例验证等。
There are few design codes taking into account of the presence of dissimilar metal welds under high temperature creep and fatigue conditions.British R5 procedure is a relatively comprehensive assessment procedure.A brief introduction of R5,Vol 6 is given in the present paper.Emphases are put on the theoretical backgrounds and validation of the procedure.
