Welding in Simulation

Simulation Generality

Hello

I have a problem with the solder connector.

I understood the method: the first body selected is a shell or sheet metal and the second thing the same thing with a volume body in addition.

If I understood the principle correctly, it is at the intersection of the projection of the first selected face on the second selected face that the cord is created.

It works, that's what you can see on the photo (red early on gray volume)

The problem is that it doesn't work with the other sheet (cyan on the photo), simulation doesn't find the intersection of the two faces??? Now, I'm stalling...

If someone could explain it to me it would remove a thorn in my side.

Hello @patbo

It's hard to help you without seeing the settings you've been using

Could you contact your little ASM so that we can see what you have taken as a criterion for the simulation.

Use the ==> file==> pack-and-GO function  by attaching the elements of the simulation all in a ZIP.

Kind regards

Hello

I do the test in a room but it's the same thing.

Attached is the file.

I'll watch and keep you informed

Kind regards

Hello@patbo

Indeed I can't do it either. while the first weld is done very well. If we want to make another weld on the other side, he sends us to graze.

Do you have access to the visiativ hotline?

Kind regards

Hello

I don't think so, but I'll find out.

I will get back to you if I have an answer.

Kind regards

Hello @zozo,

I got an answer!

Although you can use volume and surface/shell in this connector, in the first input you have to select the body that projects on the face (my beam).

However, in my case, it's a volume, so it doesn't work...

To get out of it, I have to transform my beam into a surface to be able to use it in the first selection.

In any case, thank you for the time you took to help me

Good evening @patbo

I took it!  ;-)  ;-) ;-)

I came to the same conclusion as you but this logic is incomprehensible compared to our simple everyday needs.

So I asked for assistance from the HotLIne and I will tell you what they say about this logic, which is a bit curious it must be said.

Kind regards

Hello@Patbo

A few questions if you go through this again ;-)

- Do you usually have a lot of welds in your ASM?

- Do you need to test the strength of your welds or what else?

- do you have the PRO simulation version or only the Basic Simulation?

- What do you expect from the results of the simulation with the "solder seam" connector?

Kind regards

Hello @Zozo,

To answer in order:

- I never represent welds in SW, I use symbolization in drawings

- I simulate welds in simulation only when they have multiple stresses (shear+tension+torsion+torque). A simple shear or a simple pull, I do it the "old-fashioned" way manually.

In the case I am currently working on, it is 2 horizontal beams of 14m connected by plates bolted together and welded on the beams.

They are supported at their ends, all with loads in the axis and offset. (see photo)

- I have pro simulation, the other one is too limited

- I size the weld and bolts using the connectors.
