Welding in FEA
Welding in FEA
(OP)
I wonder if someone can give me the recommendations to this topic. I'd like to know the way the welding is analyzed in FEA. Please, shear your work experience & observations. What features of FEA exist?

or
You take the loads or stresses next to an idealised simple joint where the weld is and consult the industry standard code for welds of that geometry.
I have done both.

operations and conformation. Is it possible to detect influence of
welding on structure (failure in the HAZ) and what the precision such
analysis?
RE: Welding in FEA
I know a FEA add-on packaged named FEWeld (http://www.weavereng.com/feweld/), a specialized mathematical tool for calculating weld requirements to meet performance criteria from the results of finite element analysis with SHELL parabolic elements, integrated with COSMOS/M GEOSTAR, Ansys and Femap. Pure "delicatessen" for any FEA user involved in Welding design.
The author Mike Weaver has all my consideration, very expert in FE welding & fatigue analysis of joints, one of the best of the world. The FEWeld User Guide is an excellent book for "Weld Modelling Guidelines for FEA", very good indeed.
Best regards,
Blas.

Either is good. Which you choose is up to you.
