The fatigue life of butt welded cast steel with additional weld metal to rectify mis-match in casting thickness (TM-STM-32)

Mis-match in thickness between castings to be butt-welded has been rectified in bogie production by building up the thickness of the thinner material with additional weld metal, after completion of the butt weld. Fatigue tests have been carried out on specimens representing butt welds between two castings, and between...
