Doing it that way is asking for leaks and rattles, and could result in a catastrophic failure of the cars structural integrity in the event of a collision.
If you really can't find a welder, just cut the patch to size and glue it in place with panel-bonding adhesive.
I believe he was telling me to do that until I am able to get a welder.
