The creep damage and early failure tendency of medium matched joint are lower than those of overmatching and undermatching welded joint, and only isolated holes are found in the test. The creep rupture strength ( ) of medium matching joint is almost the same as that of undermatching joint. The creep rupture strength overmatching joint is the least one, therefore, it is reasonable that the medium matched is used for the dissimilar welded joint between martensite and bainite steel.
