2024 Aluminum Weldability. Welds well using tig welding, not as strong as 6061 aluminum, but still offers great durability and resistance to fatigue cracking, and more suitable for structural components than complex parts. In order to perform the integrity assessment of the dissimilar welded.
There is, however, an exception to this numbering system and that is for 1000 series aluminium; When heated to a molten state an element in the 2024 (specifically the nickle) groups together thus changing the alloy and weakening the metal as it solidifies.
