Testing Welds in solidworks

[Cahop]

Hi All,

I have a rack system created on solidworks and I can not figure place a weld between two components in an assembly the run a FEA on the assembly. So far I can only run FEA on a single part. If anyone could help out with running an FEA on an assembly and how to put a weld in that would be greatly appreciated!

Thanks Folks!

You probably don't want to put a weld in if you are after stresses in the weld. Welds are complicated due to residual stresses. It would probably be better to join the parts together, find the stresses in the joints and then use an appropriate factor to account for the weld.

If you cause the parts to touch you can bond them together.

Wouldn't that factor change for some of the welds as some are fillet welds, some are butt and others are lap joints?
Cheers for all the help!

You might want to search the Finite Element Forum for discussion of weld treatment in FEA.

You might also want to check and see if your industry has standards for dealing with this.

You are correct, different welds are treated differently. The AISC handbook has a discussion on this subject.
