With larger blade and with blades where a strong joint is needed you will braze. Too much heat, taking too long to get silver braze to melt will cause flux to get used up dissolving oxides and go black and no longer work and also more time for blade to expand and the overlap joint to slip over it self getting a thicker joint with possible thin spots on both sides after grinding back. File or grind the blob of solder off flush with the surface of the blade and flat off the blade edges to allow smooth running of the blade through the saw guides.

I thought I’d post about how I braze my own blades for my metal bandsaw. 04-10-2006, 10:26 PM #9 Blade Brazing Woodcraft carries a kit to braze blades, which includes holder, silver soider, and flux.

Is it worth sharpening bandsaw blades?
Since a carbide-tipped bandsaw blade will cost well over $100, spending a third of the cost of the blade (or more) to get it sharp and working like new again can make financial sense. However the majority of bandsaw blades, the Wood Slicer included, are not worth spending money to have sharpened.
How long do bandsaw blades last?

What is a blade welder?
The T27555 Blade Welder can cut, weld, anneal, and grind bandsaw blades. This allows you to make new blades from bulk coils of band stock. Quickly rejoin a blade that has been purposely cut for making an internal contour cut. Repair broken blades that are still sharp and useful.
Does welding melt metal?
Joining Metals As opposed to brazing and soldering, which do not melt the base metal, welding is a high heat process which melts the base material. Typically with the addition of a filler material.
How tight should my bandsaw blade be?
The blade should deflect no more than 1/4 in. A good place to begin is to tension the blade until the meter reads proper tension for the next wider blade. For example, if you’re tensioning a 3/8-in.
What causes bandsaw drift?
Drift is cause because the blade buckles under the load. You can see that by stretching a ribbon between 2 points and applying a pressure to one of the edges, it will turn sideway easily. A sharp blade and high blade speed will help a lot with that.
