by the time you have paid someone to weld it and refinish the barrel , you more than likely could have bought another barrel for the same money .
Yes but since I already have this barrel I would like to fix it . hate to see $90 go to the scrap heap.

and yet maybe that is where it belongs .................... or sell it to someone with full knowledge of what is wrong with it.
Maybe it does...but maybe it doesn't .
Doesn't matter. Welding only on the one side will pull the metal towards the weld.
There ARE ways to peen that stress back out. I'm thinking a tight fitting arbor in the bore and then peening the weld with the ball end of a ball peen hammer to stretch back out the metal in the weld and just in the last mm around it. Done well the peening/stretching will relieve the stresses in and around the weld are due to the shrinkage of the metal as it cooled. Also heating up the whole end to somewhere around what it would take to melt soft solder and then weld would do a lot towards minimizing the shrinkage stress.
It's not something I'd want to do on a rifle barrel at all. And not something I'd suggest for any part of a shot gun bore that was closer to the chamber. But that close to the muzzle? I don't see it being a bad thing.
Thanks but I am not worried about some very light shrinkage on a 12" blaster.
Yep, this.
It's a shotgun barrel. There is no heat treat, unless it was to completely anneal it (make it fully soft).
There is no expectation of sub-moa accuracy.
It'll be fine.
Try to set up a back purge or a copper sheet inside the weld area to minimize the amount of clean-up work required.
If you have a TIG welder, anyways, or a tame one to use.
I might not attempt this with a stick welder, but would not worry much about using a MIG, just gonna be a bit more cleanup to do.
The pressures involved, even around the breech, on a shotgun, are not nearly those of a centerfire rifle.
Not worth agonizing much over.

Send it to me, with return postage, and I'll weld it for you. It won't affect SFA, and make you feel better.
Shoot me a PM.

.10 to .15 mm is .004 to .006 , that's a scratch, not a cut.

I'd weld it.
