We just bought a spool of band saw blade stock and we want to cut it
in sections and weld blades. How do we weld them so that they hold up?
I used to silver solder them, with mixed results. Some held for the life of
the blades, some let go in minutes.

I have welded blades on the Do-All saw at work, and it is AMAZING. No
training, just clamped a blade in there, set the dial and pop, beautiful
weld. If you can get one of these, do it.

I have an antique German blade welder that apparently has home-made blade
clamps. They are pretty good, but not quite right, and sometimes one blade
end climbs up on the other one. I keep fiddling with it, and it gets a bit
better. But, I can usually get a weld that will work for a couple months,
but they often fail before the blade is completely worn out. I make my
blades extra long so I can re-weld them a couple times before they get too
short.
