A round knockout metal plug from an electrical box works fine as a back-up
plate for small holes. It gives you something to weld against. It also makes
for
lots of grinding if you want the back side finished.
I like the copper idea. Thanks for the tip.
Here is what Richard Finch writes in Welder's Handbook, "Weldors (that's what
he calls people who weld--whoever picked the book title didn't know that) use
strips of copper to back-up their welds in their sheet metal because copper
will insulate the weld and because it won't stick to the steel, stainless steel
or aluminum that is being welded."

well, im not a welder, but i have watched a 2 friends of mine fill
holes.....first you get a scrap of plate copper thin enough to bend to the
same body
contour as area with the hole...place the copper behind the hole.then he
uses an
electric welder that feeds wire automaticly.no plug is needed ,the molten
wire wont stick to the copper just fill the area with weld.remove the copper
plate grind and finish as usual...again im not a welder,but those of you who
are
check into this procedure ,my friend swears by it....steve
