Project #9 from Worntorn - tig weld broken bandsaw blade

[worntorn]

It's Sunday morning, and I am looking forward to building a Stainless steel kickstand for the Egli project. I have thought about the design for a couple of days and I'm ready to go. Almost.

I forgot that the last time I used the Wellsaw the blade broke. I don't have a spare at the moment and the Industrial suppliers are all closed.
It was still cutting like new when it broke. It got jammed in some 1 3/4" solid stock I was cutting to build a 75 HP. pto shaft for my tractor mower.

I was ready to write the day off to lawn mowing and weed eating rather than metal work then thought I should try tig welding the blade back together. Some metal cutting bandsaws have blade welders built right into the machine , don't they?

It's back on there and cutting nicely. It will be interesting to see if the weld holds up.
The filler rod I used was some 1/16" 309L stainless. I can't tell you what is happening Metallurgically when using 309L on a bimetal blade, but it seemed like it might just work, given past experience.
