My undrstanding of the brazing process is that it doesn't melt the parent metals, but flows the rod metal into the join. In simple terms I see
it to be a similar to bonding the parent metals. That said many adhesives have properties that allow them to actually flow into the parent material
(particularly for timber and plastic adhesive).
I'd guess brazing may be OK for space frame type chassis of limited lifespan, but not for ones intended for long lifespans such as road cars.
Similar to the way I made my racing frames in the 60's, but I used silicone bronze welding, just a bit quicker than brazing.I get the holding
your breathe though

Holding your breath is definitely a concentration thing
When I do it SWMBO tells me to "BREATHE MAN"
I've told her time and time again "not breathing means I'm not concentrating!"
I recall shooting a rifle laying down in a shooting range being taught to breathe in then out and aim/fire at the bottom of the out breath when your
body is still.

Kart chassis used to be bronze brazed like this. It gives a little flex to the joint I believe without being too ridged. Not sure if they are still
made this way?
As I understand it the joints can be as strong as a welded joint, with the slight flexibility an advantage for fatigue resistance, also the parent
metal does not get a heat affected zone and you can join dissimilar metals or very thin metal to thick metal more easily.
