I have an unused band saw blade that was hanging on the wall still in it’s original coil. It accumulated a coat of surface rust. So, leaving it coiled, I soaked it in a 50-50 vinegar and water mix over night. The following morning, I found it with the original factory weld separated. I can only assume that the vinegar caused the weld to separate. I never imagined that that would happen. Anyone here have any experience or knowledge about this?

I've never heard of a blade soaking in vinegar, so can't help there. But I would guess it was a combination of a subpar weld, rust, and then removing the rust, that caused the weld to break.
I've had blades separate at the weld from light use. It happens.
Yes. As a mild acid, vinegar is an excellent rust remover. I recommend you try it. A 50-50 mix of white vinegar and water works well.
You may be correct about this particular weld being sub-par to begin with. Then the combo of rust and vinegar finished it off. I have since done the same with another old blade with no ill effects. I think it was a better quality blade to begin with. I have since silver brazed the first blade. So, it is ready to go if needed.
