What I want to do is join some scrap metal together to make a sculptural
object for the garden (don't ask). A mix of sheet, rod and lumps. I
won't be able to accurately identify the type of metal - probably steel,
iron maybe some brass? (no aluminium). I need to get acquainted with the
methods I could use to do this. So far the likely methods seem to be mig
welding, tig welding or brazing. A quick search show some tools that are
basically electric and a different type using 2 bottles of gas. Since I
will be joining lots of different objects I need a method that's as
versatile as possible. Is there a dummies guide somewhere. Which of
these methods should I be learning about?

If you stick to steel, then ordinary arc welding is cheap. If you need to
join two different metals, and they're compatible, you'll need brazing.
And brazing sets are as you say two types of gas and much more expensive
to buy and run.
