TIG works nicely, but not everyone has one or knows how to properly use it. It takes a couple of second to start a bead. This is unwanted heat.
Oxy/gas might be the preferred method of the accomplished welder, but a lot of heat can be introduced if not really good at it. The trick here is to use a real, real small tip and MIG wire as the filler because welding rod smaller than 1/16th is hard to find. And, get some Cool Blue welding heat sink paste.
If a team were to do the welding, that would be ideal. One to weld, the other to hammer and cool. One just doesn't have enough hands to handle the torch, the welding lens over your eyes, find the hammer and dolly, then hit the weld with air or a wet rag. It's like juggling. 3 balls, 2 hands

If you like to gas weld you would really like one of these. I have had the weldit mdl 101 for years - it is a great tool.

Victor, for one, makes the small tips good for this kind of work.
