Yes, we can use finite element analysis to analyze the welded joints. The model needs to be developed accordingly and it also suggests where the strength will be less or it might probably fail. There are books on Computational Welding Mechanics. Do refer them.

Thank you very much, and I appreciate your replying , but now I am collecting data about this topic and i want more details because my graduation project is in this field so if you can send my more helpful links or books or more detailed things about that , thank you again

I could add, that finite element metod could be used also at simulating temperature distribution in welded samples(at choise of respective heat source-point, linear, distributed etc.) In concentrated energy sources (namely electron beam or laser) such calculation could give some data about geometry of weld and HAZ.

Thank you prof.Georgi Mladenov , and I wish if you could help me with more details concentrated on my project , any books or papers related to (FEM OF WELDING PROCESSES) especially which related to residual stresses

I think this book may be sutable for You

COMPUTATIONAL WELDING MECHANICS by John A. Goldak , Springer 2005

I would like to add to Muhammad farhan :

Zaied, you can study many papers related to welding, ofcourse i would suggest you to read by choosing particular field in welding either like, SPOT WELDING, BUTT WELD, LAP WELD, LASER WELD etc, then you can take some more parameters that can improvise the study.

Thanks for every one, Sukesh Nerolu, Muhammad Farhan ,David Barlam .

And I appreciate your efforts to help me in my project, but i can tell you that I STUDIED many course in welding and recently i finished a NDT course APPLIED ON WELDING , so now as you see, I am collecting information about my GRADUATION PROJECT. SO I've my own background ,but you know this project i don't have any information or experience about it.but recently i downloaded many many papers and thesis about this project so i began to understand what I'm going to do , but still unable to cover all points of my project , so if MR Muhammad Farhan can help me by any additional data ??

and thanks every one again

okay, i am talking about ( welding processes, single pass, thermal stresses ,& residual stresses,by using abaqus
