Brittle fracture analysis of Dissimilar Metal Welds

This paper deals with a fracture mechanics analysis of a narrow-gap Dissimilar Metal Weld (DMW) in the brittle fracture domain.The considered case is a Ni base alloy weld joint between a ferritic component and an austenitic pipe and the aim of the present study is to show that in the same loading conditions,the weld joint is less sensitive to the brittle fracture than the nearby ferriticsp.info What should weld joint design be for stainless steel?For duplex stainless steels, a weld joint design must facilitate full penetration and avoid undiluted base metal in the solidifying weld metal. It is best to machine rather than grind the weld edge preparation to provide uniformity to the land thickness or gap.See all results for this questionsp.info Radiographic Testing Procedure7.3 Welds Joining Dissimilar Materials or Welds with Dissimilar Filler Metal.
