Hi, just wondered what your opinions are and whether there's been any research done on the subject ?
If sleeving is the only option to save a beautiful old gun, the Tig work is done properly and they're struck up well , the job would certainly be pleasing to the eye , but I've often wondered what ( if any ? ) effect there is to the area immediately next to the welds on the old damascus or laminated breech end of the joint ?
I realise there's a nice sleeve of new steel running through and into the chamber, but after seeing instances where different metals have cracked or broken off next to the weld through either the wrong filler rod being used, the black magic of chemistry or lack of necessary heat treatment it got me thinking. I'm not an expert welder but have worked as a fabricator in the past.
Could the heat, even though it's localised, compromise the structure or integrity of the original blacksmith welded tube ?
Any input or ideas Gentlemen ?
