Abstract
Multipass circumferential butt-welding of stainless steel pipes is sim ulated numerically in a non-linear thermo-mechanical FE-analysis. In p articular, the through-thickness variation at the weld and heat affect ed zone, of the axial and hoop stresses and their sensitivity to varia tion in weld parameters are studied. Recommendations are given for the through thickness variation of the axial and hoop stresses to be used when assessing the growth of surface flaws at circumferential butt we lds in nuclear piping systems.
