We have done that same repair a couple of times.
Bored the taper out of the damaged hole.
Made a steel bushing : cylindrical O.D.; tapered bore; split down one side.
Advised customer to re-tighten the draw-in bolt occasionally.
Are your weld zones long stretches of shaft or short zones?
If short. I think the cold wire tig is the right thing.
We regularly do build up and re-machine on slender stainless agitator
shafts from 7/8" to 1.50" dia.... short seal zones and bearing journels.
I have had success machining replacements for rubber sealing elements
from PTFE. Round objects are easily lathe turned from bar stock.
Years ago I machined PTFE vee stacks in a size I could not find.
Mcmaster has now added that size to their list (9572k32) so I no longer

If so, stretch or squeeze to improve the "roundness" then check against a flat surface and sand the...
It is unusual to see a lip seal size that cannot be found
in Dichtomatik's (800-328-2840) catalog list.
However, Garlock did make a lot of unique sizes for OEMs
which can no longer be found.
TCM_Dichtomatik does list a couple sizes that might work for you.
A metric 71x88x8TC...
Years ago, I was design/building cheese cutting machinery.
Needed to mill a deep pattern in the face of a platen 12"x 28"x 2".
predictably ; the UHMWPE we chose warped very badly. (an inch or more over 28")
My supplier was Eiler/Seely Co down in Bloomington. ( now "Activar")
Might such a product be produced by a specialty "wire drawing" company ??
Perhaps in short run quantity...
McMaster lists "cold worked" Ti hexagons 7/16" and larger.
Could they help you find or source it for you ??
