DOM weldable surface area question

Making control arms.

1.5" OD tube
1.5" joint housing width

Is there enough surface area to weld the two pieces together? Considering the joint housing staying the same 1.5", should the tubing be dropped down to 1" OD, or is the 1.5" on 1.5" ok?

A CAD illustration:

Grind a bevel around the side of the arm tube to give you a pocket for the weld.

What joints are you using in those? That's a small ID. (if drawn to scale)

Haha. Definitely not drawn to scale. It's what I'm good for in MS Paint.

thought the narrowest one was 2".

they have a snap ring groove around them, id' be careful about burning into this groove. The snap ring won't fully seat.

These are the 2.25" diameter, 2" joints. The joint housing width is 1.5". The joint itself is 2".

Brain fart. 2" mounting width. Durrrr.

I assume with 2" joints these are for uppers. You'd be fine with smaller tube. Currie uses 1"x.156" wall DOM on all their arms, upper & lower. But if it were me, I'd still use the 1.5" on the lowers, they're wider & shouldn't have a problem.

Yes, these are for the rear uppers. I bought the joints a while ago when I was looking for projects to do. Ironically, I never got around to it, but it's time to do something with the parts. I will probably just buy them made from MC next time, but it seemed like a good project.
