welding pin in hole

[inventorguy]

having trouble welding again today... i have a round pin sticking out of a round hole of a plate and i would like to do a fillet weld around the pin to the plate... however... the hole is bigger than the pin so to my knowledge i have to fill the gap first with a groove weld but when i try that it only fills like half way around or gives an error... i click groove weld... click the cylendrical hole surface... click the cylendrical pin surface and click an edge that is perpendicular to these surfaces as the fill direction... am i doing it wrong? i even tried "full face weld"

[inventorguy]

i finally figured it out... using like 10 steps

[inventorguy]

these are the different steps

[inventorguy]

here it is finished

[inventorguy]

so that was just a couple test pieces i was try to figure out... let me see if i can do this in my actual assembly...

[dxpal]

I was able to replicate the example provided, but I still don't understand the theory in why it works this way.
Change the workplane split location......

You could have saved yourself a LOT of time and trouble
by:

1. Posting the Inventor version used. We cannot read your
mind, not can someone post a solution in your version without that info. ( I do
not have R10 installed on my system any longer.)

2. Posting the actual files.

3. Posting your test files earlier.

In your test files, I see several things not needed, ie; the
splits on both parts. Not needed. Remove them and associated work
features.

1. The pin is exactly the length of the plate's thickness. Why
would you do this in real life? Make the pin longer.

2. Split the pin only, AROUND the circular face, so that it
has a face .02 longer than the plate thickness. Constrain the pin flush to one
side of the face. (Mate/Flush or your original Insert constraint
works.

3. Proper Pick sequence and settings are attached. Filean
result - next reply.

u dont have to read my mind... i posted the version of inventor i was using in post number 2... 3rd post from the top... in my real assembly my pin is longer very similar to the examples u were posting... out of frustration i was trying to figure it out using simple methods hints the pin/plate being the same thickness... ive tried it with no splits... tried it with the pin split only and the plate split only... and out of frustration tried splitting them both... still no luck... but that just happened to be the one i posted... was finally successful doing it a way seeming to be much harder than should be needed but doing it that way i used no splits... go figure... but ill take a look at doing it with a split a hair bigger than the part as u suggested... it might be a while because i have a meeting...

Here's a sample made in Inventor 9 that will open on your
system.

I'm not sure why a split the "exact" size of the plate
thickness noes not work either. However this is the technique that will work
with R10-IV2009.

seems like ur instructions were pretty simple and clear but as i try them i just cant get it... see my attachment... i have given every detail of what i did but i forgot a few things... i used insert... they are both separate parts... in a weldment... using insert... the pin is .5 inch... the hole is .75 inch... the plate was extruded from a sketch including the hole... in sheet metal... the bar is extruded from a circle as a regular part feature... i cant see what im doing different than u?

I created my last test files in Inventor 9 (not 2009).
Did you open them and try that set? I then tested them in Release
11.

If my set fails, then make sure that you have ALL service
packs installed for version 10. Help > About Autodesk Inventor - should
reveal the service pack level you are at.

ok... ur parts worked great... like magic after all this time... i tried to remake ur parts exactly as u did... works like magic... tried resizing the hole to a smaller size... .75 inches to match my example... works like magic leaving only one possible explanation... which is that inventor can not do this if the plate was made using the sheet metal feature do u agree? could u try ur same example using sheet metal?

It's not magic.

Post your parts and assembly, zipped.

ok... so i went to get the files to send it to you... and thought id try one last time to make sure it wasnt working... and like magic it now works on the sheet metal part... i dont understand? i didnt do anything different than i did before? if u remember this was my origional post... but then discovered i had used the wrong part and the part i was supposed to use was the same size (pin/hole) and therefore i actually had no gap to fill... however i continued wanting to learn this technique because i do have some round parts and gaps that do need to be filled... and they are acting very similar to the pin/hole problems i was having and i figured that if i could figure out the pin hole problem then i could figure these out too... but after all this... things seem to be working like magic... and im not sure why they just work all the sudden... and without knowing what i did to make it work... i cant make this work either... so im attaching it and heading home til monday soon... i have a feeling this will be a tad trickier than the pin/hole... although i have not tried spliting the faces of these objects like we did before... perhaps thats all i need to do? u helped me make this "shell" its sheet metal... its a circle... very slightly broken... then using contour flange it was created... the "bowl" was created as a regular part... using a revolved sketch... what i need is a big beautiful weld that can be seen from the bottom as in on the outside not the inside... the bead size is .07 inches... this is only a visual thing so any preps are fair game but changing the part is not... for example making the bowl bigger... i need the flat pattern of the shell so making it a regular solid extrusion or revolution is not acceptable... i figure the first step to making this happen is a groove weld to fill the gap in the "shell/bowl"

You might refer to this book http://www.amazon.com/gp/product/0470293144?ie=UTF8&tag=mc02c-20&linkCode=as2&camp=1789&creative=9325&creativeASIN=0470293144
pg 289 Fig 10.32 & 10.33
And of course the "bowl" will not return a flat pattern.

Hi, currently the workflow for such condition is to create Groove Weld to fill the gap first, then create Fillet weld
The issue to simple the workflow is a known issue, and has been added to our quality database.

PS: I would suggest you add all your inventor files in one ZIP file and attach it the next time if necessary:)
Thanks
