Abstract
SCC growth tests on the specimens machined out from SMAW and GTAW weld joints of low carbon type 316L stainless steel were conducted in simulated BWR coolant condition to clarify effect of loading direction on SCC growth behavior near weld fusion line. Results suggested that SCC in the base metal tends to propagate to avoid the weld metal and the relationship between dendrite orientation and loading direction affects SCC propagation into weld metal.
