Welding to curved surfaces

I am looking to properly represent the way we weld pad eyes on to pipe. In our process we place the base of the padeye tangent to the pipe and fillet weld it to the pipe. I have found several work around's but this will not properly analyses when I pass the model to out FEA program. Does any one have any insight?

Will the emboss tool give you what you need?

I don't think so. It would probably give the visual representation, but not the physical properties I will need.

Hi Mark,

I've put an example in customer-files (using the same subject). First I
made a weldment assembly using the groove weld tool to get the desired bead
geometry. Please examine the padeye component and note the split features I
used to define the bead surfaces and the work features that control the
beads fill direction. After this I created a new part and derived in the
weldment. The FEA was performed on the derived assembly in Inventor 10
professional. I'm not sure if this will be successful in your FEA software,
or even if I did it accurately. However, it might give you some news ideas
on how to get around the fillet tool limitation.

Regards,

Thanks for the work around. It is a bit of work but will give me what I need. Is there any plan to add the ability for the fillet weld to work with flat to curved surfaces?

Hi Mark,

Currently fillet welds handle hole gaps well. (For example: cylinder going through a block which has a hole in it)

I took a look at this case and it has a gap between the two components. The side view image is attached and gap is shown as black lines. Fillet welds don't handle this kind of gap currently.

Gap and groove welds like Harold demonstrates is the recommended solution for this kind of gap case. Thanks.

PS: I have posted examples on fillet with gap in this NG. Please search if you need additional information.
