We analyze the operating characteristics of welded joints of austenitic high-nitrogen steels. The influence of hydrogen- and chloride-containing media on the structurally sensitive properties of heterogeneous welded joints is investigated. It is shown that the heat-affected zone, where the residual welding stresses are superimposed on the stresses caused by the influence of the ambient media and in-service defects, proves to be especially sensitive to the influence of hydrogen degradation.
