Hi

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?

An arc welder with rods that are Indiscriminate will do this. The rods are
a touch more expensive than normal ones, but they will allow you to use
differing metals with no problems.

Great on stainless steel to other metals as well. :-)
