When welding spring steel I like to TIG weld with 312 stainless or music
wire, clean area, then heat with a torch. Let it turn yellow - brown -
purple and then just as it starts to turn blue, stop heating. Do not quench
it.

As for the woodworking part of this thread, I clean the shop of all wood
shavings and chips prior to any welding.

I made some invisible shelving brackets by welding a lag bolt minus head to
the end of a 1/8" steel plate approximately 1" wide by 4" long. I mounted
them using a portalign type of attachment on a drill to go into the wall
studding,
so they'd come out of the wall at 90 degrees. They work pretty well but
would
bend if enough force was applied, so I was wondering if they might be
stronger
if made from spring steel. My question is, does spring steel retain its
properties
after being welded?
