I`ve had good luck grinding a scarf joint on the ends and then using silver braze to join.
If you have a machine shop close they probably have a blade welder that they use to make up their own blades and can weld yours for you.You will pay whatever the shop minimum is to have it done so may as well bring all the blades you have and get them done too.

When ever you bring heat treatable material to a high heat and cool it quickly, you have hardened it. AFTER IT COOLS TO ROOM TEMPERATURE, you have to temper (draw) it. So, after it has cooled to where you can touch it, you need to re-heat it, depending on the material, to at least past blue. By drawing you should be able to get more consistent results with your TIG welding.

Scarfing and silver brazing is a good way to go. Whatever way you go, be sure to maintain the tooth geometry, don't have a big gap or two teeth too close.
