Title: Reliability Improvements in Repair Welding of High Strength Steels
Published: July 01, 2002
Abstract: Engineers often have to deal with repair of weldments after they have been put into service. Here, the concern is that the service environment may have changed the structure, indepent of whether the problems originated during the initial construction (cold and hot cracks, inclusions, porosity, etc) or during subsequent service service (wear, damage, stress corrosion cracking, etc). In the case where the material characteristics have changed, the welding procedures used during the original construction may no longer be appropriate. Thus, it is necessary to create a new welding procedure qualification, which will define the specific details for an appropriate repair, using common welding processes. In this paper, emphasis is given to repair welding of railway tanks manufactured from high strength steels.
