Determining Stresses in a Weld Seam

Hello

I used the solder connector but with its limitations........... An alternative is to make the cordon with a defined apothem, and to do a volume sweep and look statically for the stresses that propagate according to the loads. Does anyone have any feedback from testing on a physical part and a comparative approach with simulation? except that it is the most relevant solution with Solidworks to obtain a qualification of a cord.

Have a nice day.

Spectrum;

my modeling on a 4 inch strong Iso tube.

I tried to reproduce the deposit of the weld as closely as possible by combining the repetition.

On a tank project with a tube skeleton, when cutting at 45° how to connect the weld connector............ Thank you in advance.

Hello Spectrum

A lynkoa bug to delete my post (once again)

I don't have the courage to start again because the subject you raise is complex, but to make a long story short, we can't describe a weld seam other than a posteriori non-destructive test.

In addition, SW is so psychorigid that I gave up on making simu on this point of solder connectors. The same goes for the model. I only make notes in the MEP and it suits welders who are great professionals and have very strict certifications.

Kind regards

Hello Zozo,

I totally understand, I will follow the right advice and limit myself to a static study without weld beads of the assembly in contact with each other. It is not possible to reproduce the real condition of the weld, which remains non-constant in its creation....... I use ASS EC3 with Excel to have a theoretical cord. I will no longer try to make the values coincide by calculation and simulation.

Thank you for your frankness.

Spectrum.
