I silver solder the blades for my bandsaw. (It's one of those ubiquitous 4"x6" horizontal/vertical import jobs that cost about $200.)
I grind/file a taper on the ends, overlap, hold the ends in a jig I made from a piece of angle iron, and silver solder with a propane torch. It takes a while, but for me it works fine.
