Distortion when welding 2 small tubes on each end...
(OP)
How can you overcome distortion in this situation? The whole thing is becoming somewhat twisted...
There are two tubes about 5/16" dia. about 3' long. they are spaced about 1/4" apart. A solid piece is being welded on each end and then a spacer is tack welded in the middle. The welds are all about 1/8" fillet welds all the way around on each end of the tubes.
See crude picture for a rough visual. Any suggestions? Thank you

first he is welding around each tube on the one side then sliding the spacer on and welding and then welding the piece on the other side...
Seems that we can prevent some distortion with the jig and then fix most of the rest by simply bending.

I would also look to minimize the welding on the center spacer.
If you have very many of these to fabricate I would look into some type of precision welding such as shown by Weldlogic, Arc-Zone, and many others.

Let the other tube be a little longer, so it extends through the end pieces plus a little vigorish, and weld that tube on the outside faces of the end pieces.
