Simulated Weld

Postby bill » Sat Mar 03, 2018 3:59 pm

Look how good my welding skill have become! :lol:
Is there already an easier way to sim a weld in FC?
Be nice to have a feature to put line of adjacent spheres(size defined,spacing defined) on any line, arc, or spline selected!
This way is quite laborius but effective for price quoting by fab-shop.

You may publish a macro for this :) .

We can add it to the future issue #1240 (Welding WB) ;)

This can be done in V0.17 using PartDesign>AdditiveSphere and suitable datum lines for path direction and linear or polar pattern transformations as shown in this simple example:

The sphere can be located at a vertex using AttachmentMode>TranslateOrigin and should be offset slightly using AttachmentOffset from the faces or the transformation patterns may fail.

Draft>PathArray can also be used for any specified path and a Part>Sphere but will require Part>Fusion to obtain a single part. The sphere should be placed at the global origin. Select the sphere first and multi-select edges using CTRL key then the Draft>PathArray. Set the number of spheres to get the overlap you desire.

Great idea, here with an elipsoid, placed under an angle:

Array of a ellipsoid? Did you take a look at the file size?

And did you ever run a BOPCheck on an ellipsoid - let alone an array of them?

It's a monster, maybe good for the next Marvel movie ... :lol:

BOPCheck, I know, that's the same like fillets on faces with draft angle.

BOPCheck, filesize, it doesn't matter, but it looks cool.

The datum line is a good idea for appending the simweld.
But the array has its drawback because of its inherent forced/symmetry. Is this correct?

And yes, the elipsoid is the basic shape of a welding/bead-puddle; but too much file overhead as mentioned; sphere is probably most efficient solution.
You could end with an ellipsoid

Spheres all in a row probably will be fine.

If one wanted to get more photo-realistic, they would interject a random-variance into the inter-bead/puddle spacing to further simulate the shakey-hand-welder effect in the macro originally mentioned.

The original model looks like yours ppmawm; its the resizing and screen aliasing that gives it that look! Easily solved above; I think!
