Re: Study set up
For clarification. This is only a small portion of the design and, no, I can't tell you what it is. Just know that, in the end, the rod will be supporting ~7,000 pounds and I need a FOS of 4.

Re: Study set up
Got it. Well you can do edge weld...but I don't know what edges you would choose. Normally you need to choose two faces and an intersecting edge to define the weld joint. Obviously this will be a single fillet weld (you access this feature in contacts). The only difficulty will be figuring out what faces and edge to choose to position the weld on the outer surface of the half tube and the corresponding thread edge of the 8" cylinder. You are right about the contacts though. You need to define contact between your half tube threading and the 8" diameter rod threading. I think you can just select the parts and automatically define the contact...if not the manually select each face and define the contact logically.
Oh I thought of something. Make your rod with the threads ...but when you get to the edge of your half tube stop the threads so that it creates a flush edge. Drawing is better than words. Perhaps you've already done this. Hope it helps a little.

Re: Study set up
Hi Jeff,
You can use the edge weld feature only if you make the half tube a sheet metal part or surface body. It does not work with two solid bodies. So you can verify your weld using that method but unfortunately you cannot check the weld and the threads using that method because in making the half tube a surface body it will then have no thickness and your threads will be lost.
Your best bet is to probably leave both bodies as solids and then create your No Penetration Contact Sets for the threads and then model a weld. I created a weldment and then used the weld bead feature and it worked well.
