I meant while the part was in service. If an engine mount was brazed, and there was an engine fire, would the braze

Dunno, Mongo.
I guess it would depend on how hot for how long.
But remember that it takes an acetylene flame to braze in the first
place.
If if gets that hot in the engine room, whether the mount welds hold or
not is probably going to be a secondary issue...

Its just gotta last long enough for me to get it on the ground ;-)
Getting it on the ground is no problem, gravity will help you with that task, now doing it in a survivable manner,
that is the trick.

Reminds me of the guy with the souped up O-200 formula racer. The engine was putting out great power at something like
3200 rpm, till it threw a prop blade at something like 2000' agl... Shook real bad and tore the engine off the mount,
but the safety cable kept it from coming loose from the airframe, so he was able to get it back on the ground "in a
survivable manner". If it had broken completely loose the CG would have been way off and that would have been the end of
it...
Same thing with a fire in flight. I would at least want the engine to hang on for a while to give me a fighting
chance...
