摘要： A welding method for two members adapted to be welded and formed of a low-alloy steel for structural purposes causing the weld metal to develop martensite transformation during cooling after welding, so that the weld metal becomes expanded to a greater degree at room temperature than at a temperature at which the martensite transformation initiates. The welding material comprises a ferrous alloy containing C, Cr, Ni, Si, Mn, Mo and Nb, all of which meet substantially with the contents of the following equation (1): 170 ≤ 719 - (795 x C wt%) - (23.7 x Cr wt%) - (26.5 x Ni wt%) - (35.55 x Si wt%) - (13.25 x Mn wt%) - (23.7 x Mo wt%) - (11.85 x Nb wt%)
