You will need a blade welder, or better yet a place to take them where they can weld the blade for you. If the blade is very worn at all, it’s likely that it wouldn’t be worth it. It may not even be worth it if the blade has almost no wear depending on what someone would charge to weld a blade. I bought several on clearance from Lowes and paid less than $3 each for a few different ones.

Brazing will hold a band saw nicely and you might be able to make a jig to hold the bands while you join the ends.
The ends must be ground to a taper so they’ll have a good sized overlap.
Brazing is just like soldering, but done with a hotter torch and silver rod.
Do some research on the internet about it. here’s a video from Charles Neal who bought a kit for this.
The video was made in 2009 and the kit from Woodcraft is no longer available. But here’s an article on building a jig from wood which works.
Here’s a video from a guy who’s obviously a metalworker, but he knows his stuff,especially with brazing a band saw.
By the way he mentions that a bernzomatic torch will work, but it also works hotter with Mapp Gas.
Do your own searches and see if this is the way to go for you.

After checking out your profile and noting age and experience level, I would suggest researching/googling instructional videos on bandsaw usage first. I suspect that you are over-feeding your bandsaw and/or attempting to cut too thick of material with your chosen blades and size of bandsaw. It is way too easy to over-stress and over-heat these small blades.

+1 on what HM said. Based on the length of the blade, you’re using a three wheel 10” band saw. These are notorious for breaking blades if they’re not set up right or you over feed the blade. You can get blades for way less than what it would cost to have one re-welded. Check eBay for prices of new blades.

I believe that almost anyone, with proper motivation and determination, can acquire the rather simple skill of soldering and brazing.
Unlike the more technological art of welding, it employs lower heat and rather than fusing a single sort of metal, it “sticks” two metals together, one which melts at a lower temperature than the other one.
In the small scale of a band saw blade, it is quite easy to do, providing one follows the procedure.
It doesn’t require expensive equipment or extreme conditions.
I encourage you to look into it as it will be an extremely useful life skill for more than just band saw blades!

I had a jig where you use silver solder to put the blade together. I have not used it in a long time but it worked great.

I’m going to bust in here, not knowing squat, and ask a bunch of questions. Awesome, huh?

Is the blade breaking at the original weld?
Would the new brazed joint be stronger or weaker than the original blade or original weld? (Kind of like wood glue makes a joint that is frequently stronger than the surrounding wood)
Would the brazed area be any less flexible than the surrounding area?

I’m mainly trying to learn these things myself, and also wondering if the OP is going to get anywhere by brazing if the breaks are occuring anywhere other than the original weld (and therefore the problem to be addressed is more a setup and feed issue)
