The whole conversation was sarcastic actually
Actually I figured it was. But I didn't want anyone thinking it could be done that way. The trace quantities of inert gasses in the normal atmosphere are no where near enough to shield molten aluminium. Molten aluminum reacts violently on contact with oxygen. So when welding aluminum, the bead area is flooded with argon or some other inert gas to prevent that.

Think of this as your typical "don't try this at home" warning.
