Abstract
Susceptibility of ThyssenKrupp VDM nickel-chromium-molybdenum alloys to corrosion cracking was evaluated. Samples with annular welds made by the argon-arc method using filler wire of the AWS A.5.14ERNiCrMo-13 grade were tested in the titania production environment. It is shown that reliable data can be generated from testing experimental models or stressed welded samples with an annular weld simulating residual stresses in a structure
