Awhile back there was a post on some tape that you could put on the
back side of a welding joint and eliminating the need for back purge.
I was wondering if this is a good idea to use of Stainless Steel and
has anyone used it? I doing some enclosures that would be a real
pain the back side to back purge. Also a name of the tape you used
(if anyone has tried it) would be greatly appreciated.
