Heat treating is only needed for certain grades of aluminium. 7000 series generally is air hardened over about a month.
Your TIG welding is looking good btw. Stainless is well nice to weld.
Have a go with some old 531 tubing if you want to challenge yourself

Now that is interesting.
My instructor was showing me how to cheat by wedging the ceramic in the cleft and using it as a guide :D Not all those little welds are done using that method tho.

Love this. Are people here familiar with Phil Vandelay on YT? He made an alu cargo bike and doesn't appear to have heat treated it. Am very curious.
