| Abstract: | The residual stresses of A/F dissimilar metal welded joints of two conditions of as welded and postweld heat treatment were measured.And carbon redistributions,structures,hardnesses and the abilities of anti corrosion were analysed and compared on the weldments of an accelerated laboratory test. We have put forward that the postweld heat treatment at a suitable temperature had a beneficial effect on mechanical properties of the dissimilar metal welded joints. |
