Yes, you HAVE to anneal it, that is the SECRET! You want to get it up to
a very dull red and then keep it there for a few seconds and let it cool
slowly. This is real easy to do on a real blade welder, they have a
switch or something that cuts the weld current down to a small fraction,
and you just pulse the button to heat it and hold it for a while, then
make it tail off with fewer and shorter pulses.

I guess you can easily do this with a Propane torch, too.
