effects such as size, surface finish, environment, and data scatter, branch piping where the geometry is truly axisymmetric while a larger 3D model (with a larger mesh size) was used to examine the reduction factor is typically applied to account for this type of weld (the ASME Code does not list stress indices for this case).

Proceedings of the ASME 2007 Pressure Vessels and Piping Conference. Effect of weld geometry and residual stresses on fatigue Jul 01, 2002 · Fig. 17 displays the effect of the weld toe radius on the FCI life of specimens B-1 to B-3 and A-3 (r=2.5, 1.2, 0.8, 0 mm, assuming other weld geometry parameters remain constant:=60°, t=15.8 mm, =90°). Clearly, the FCI life increases with the value of the weld toe radius (r) by modelling approach. This phenomenon occurs because

INTEGRALLY REINFORCED OUTLET FITTINGS - WELD SIZE - ASME Jan 10, 2005 · I am well read on SIFs and your information is incorrect. Read, for example, "Effects of Weld Metal Profile on the Fatigue Life of Inegrally Reinforced Weld-on Fittings," Woods and Rodabaugh, First International Symposium on Process Inustry Piping, Dec 14-17 1993, MTI. There is no correlation between weld size and SIF.

Effects of Weld Geometry on Residual Stress and Crack

The variables of weld geometry included three weld heights (weld sizes) and three groove angles for each weld height while keeping the same weld size. The analysis results indicate that the overall weld residual stress decreases as the groove angle increases and higher residual stress magnitude is associated with certain weld height.
