https://en.wikipedia.org/wiki/Convair_B-36_Peacemaker I have seen a ski-plane ski marked "24S" (pre-1953 designation for 2024 T3) and it was gas welded. I have not seen other examples of tig or gas welding of 2024 alloy in aircraft production. I do know that the Aluminum Association rates 2024 weldability as a "D" - compared to alloy 2219, a ballistic material used in the early A10 Warthogs as a welded tub to protect the pilot - later replaced by welded titanium. This article I grabbed on a quick search describes fairly recent aluminum welding recommendations: https://books.google.com/books?id=DZ...uminum&f=false It does not mention 2024 as being weldable. Rockmount Research, on the other hand, sells a filler metal designed for 2024 and has for many years. It's specific applications in aerospace are above my pay-grade. I believe the filler is designated as "Neptune TIG." I heard some years back that Trek Bicycles (and maybe Cannondale?) had their weld engineers work out welding of 2024 for their bike frames. So far, I have not spoken to anyone there about that. I guess the bottom line is that some can weld it, but at the levels of the Aluminum Association and their tech reps, welding 2024 is rated as a "D" - or as Paul Dickerson told me once, "Screw it!" ... or rivet or bolt or bond it. ![]()
