Aluminium is also not the easiest to tig weld, very unforgiving. Clearly if you are a coded welder by trade its not an issue, but for the average lay person, its pretty difficult to get a clean run.

I am a lay person with welding, I own a Tig and Mig and have even welded aircraft aluminium ladders, its not an easy thing to weld with clean lines. Tig and stainless or mild steel, dream stuff to weld.
