I know many of the bandsaw blades appear to be spot welded together and I don’t happen to own a spot welder by I have read of people who have solder the ends together with good results, so that is what I am going to try.

I fired up my propane torch smeared an abundance of flux on the aligned bandsaw blades and just ran the flame through the joint until I could get the solder to melt at which time it flowed nicely between the 2 parts of the blade.
With my little Dremel handgrinder I grind off any hump of solder so the blade is smooth.
