Thanks.

There are three instances in which you'll want to join a bandsaw blade:
1. when making up a new blade from roll stock
2. when repairing a broken blade
3. when cutting and joining a blade to cut an inside shape

For #1, get your blades welded to length by the manufacturer or
distributor. They will do a much better job than you will.

For #2, this doesn't happen all that often. Usually, by the time a
blade breaks it's pretty well worn. But you can repair by either
welding or silver soldering/brazing. Welding is probably stronger, and
doesn't require overlap scarfing, but it is usually done with
specialized bandsaw welding equipment - not your basic home welding
setup. For occasional breaks, I'd save up a few blades and then have
them re-welded at a bandsaw shop.

#3 is the real reason to want this capability yourself. If this is
something you don't need, skip it. Most users don't need it. If you
do, though, you should consider a dedicated blade welder for heavy use,
and silver soldering/brazing only for occasional use.
