摘要：

Recently, stress corrosion cracking (SCC) of core internals and/or recirculation pipes of austenite stainless steel has been observed. SCC is considered to occur and progress near the welding zone because of the weld tensile residual stress. In the present work, thermo-clastic-plastic analysis of the residual stress was performed in order to clarify the effect of several parameters (diameter, thickness, number of multilayer welding) in the circumferential welding zone. Butt welding joint of SUS316L-pipes was examined. The residual stress was calculated by three dimensional-model and axisymmetric model and the results were compared and discussed in detail.
