Hello
I would like to know for solidworks simulation if SolidWorks takes into account the welds between each part?
I have a sheet metal with an area of 2 m2 with angles as reinforcement. The welds are not shown, but the angles and the sheet metal are made in the same piece.

Hello vincent.fabre_l,
I'm not a pro on this subject, but for simulation for sheet metal, SolidWorks doesn't support welds. To make a simulation, it must be a single one-piece part, i.e. your assembly must make it a part (Isolate your part to simulate). That's first.
it would be nice to know your SW version with a small screenshot of your room to simulate...
Here is this link which I think will allow you to know a little more about the simulation.

Hello @vincent.fabre_1
I confirm what our colleague @A.R says (whom I salute in passing), but I would like to add that only spot welding is taken into consideration
Conventional TIG MIG and argon welds are not taken into account.
In addition, any weld seams present in the SolidWorks ASM are not transmitted to Simulation, which is another software.
This is a debate that we have regularly and to make a long story short, we must consider that the volumes are interdependent. (sheet metal and angle)
Once you have done the simulation in these conditions, you can easily make scenarios that correspond to a simulation without the sheets and another with the sheets.
In addition, you have to refer to the weld charts which give you the resistance according to the length, etc...
But as @A.R says, without the full ASM, it's hard to say more. Indeed, like knowing the stiffening effect due to sheet metal. If the sheet metal is really stiffening, then you will have to proceed differently.
Kind regards
Hello
I'm not an expert in simulation but here is a little tutorial I had made to transform your assembly into a part but this part keeps a link with the assembly so that if you modify the assembly the part will follow.

Hello ZOZO_mp,
Thank you for your confirmation.
One question, so in the case of a mechanically welded assembly or others, if we want there to be weld seams in the simulation, then, shouldn't they be physically represented (draw them in 3d)?
That's just a question...
To be continued, thanks to more.

Hello
Yes, that's right. Ideally, you should also put small air gaps between the parts/bodies so that the parts are only bonded by the welds.
If the part is drawn like this you can have a very realistic simulation.
The big disadvantage of this is that you will spend more time drawing the part for calculation than your production part since you will have to draw all the welds realistically.
Good evening @ All
I took the solder bead type connector and I provide some clarifications
This type of connector only works for sheet metal or surface. So for mechanically welded frames, well it's rusks.
I did a test simulation with two sheets of metal and well the results don't give much, at least nothing about the solidity of the welds (see the attached video).
I come back to what I recommended earlier, namely to reason with weld charts in the same way as one should do for bolt connections.
This is why I do not share at all the solution of our (preferred) @froussel because it will not bring anything significant compared to the method of contacts in solidarity or without penetration.
For fun here is a chitit' simu made with the " solder bead" connectors
I pushed the envelope a little far, but only so that the welds and their role in the simulation appeared.
Note that this says nothing about the weld itself but it indicates the behavior of the parts at the place of the weld
EDIT: I redid the simulation so that it better answers the initial question
