there's a thread in swap and trade here: barrels with holes linky I knownothing at all about metal, barrels or welding, I'm just curious about this from an academic standpoint. Is this a legitimate fix for a set of barrels, not so much from a cost perspective (i.e. maybe not for this set, but maybe on a set of tubes with a higher value) but from a strength perspective? I'm curious if anyone has done this and if anyone has thoughts on it.

I saw a Perazzi for sale once that had ports welded closed. You could not see the welds inside and had to look damned hard to see anything on the outside. There's not too much stress near the muzzle and welds closer to the breech might be a different story. Anyway, the owner was honest about it and offering the gun at about 75% of what an untouched gun would have been

I have had 2 small splits welded near the barrel ends, one on a Parker the other on a Smith. Both were done by Freddie Bruner in Escondido, Ca. Done well. I shot Dove this season with the Parker and had not one problem. The Smith I have not used yet.

I saw Oscar weld a damascus split near the muzzle. After refinishing it was almost invisable. bill

I have welded a set of sleeve barrels into the original breach assembly.

Just one word of caution here lads- HAZ (heat affected zone) input could cause solder to break loose-and welding heat causes stresses, so a mandrel or chill bar might be needed to prevent and "out of round" condition on a barrel- FYI-

Run, I'm sure that all "hot" work will be completed before the relaying of the ribs.

Along the lines of "chill bar" and such; when welding a barrel, it will cool quickly due to the cooler surrounding barrel. This can cause what is sometimes referred to as "self-quenching". On barrels with enough carbon content, this will cause hardening, usually right along the weld edge or even on the weld itself. Many fluid steel barrels made in the early 20th century have enough carbon to harden, I suspect, since these are often early proprietary versions of chromoly. So, a normalize or anneal step can be used to get the steel back to a softness that can be filed.

I am constantly amazed at the wealth of technical knowledge available from the members of this forum.Hell, it even makes me feel smarter!

How does all this translate into welding, heat sinking, and annealing Damascus? Annealing and hardening barrel steel makes me nervous, whether fluid steel or Damascus. What about leaving all of the annealing out of the equation and just filling the void in the area of the repair for strength?
