Dave, you are confusing "soft" silver solder with "Hard" silver solder aka
silver brazing, which is explicitly allowed by the NEC. Most places don't
do it, because Cadwelds are easier, but ask the local engineer at the say
AM radio station how they connect their grounds, or the local cell guy how
they attach ground straps - yep, call in some guy with a welding torch and
some real silver solder
