I tig, mig and stick weld steel, aluminum, bronze and do a little stainless steel work. I'm not picking up a propane torch unless I'm soldering copper and even then, I prefer acetylene and silfoss.
I've never had any issue bleeding my diesel, probably because when I'm messing with coolant, I have the front end up on ramps. I fill it up, start it up, watch for the thermostat to open and add more coolant. After a short ride and cool down, I'll top up to the Kuhlwasserstand! ;-)

The rust is on the inside and welding is a misnomer (I used the term welding because the ads claim it will weld any metal to other metals). It is actually a brazing or soldering process. I would be brazing over the exterior of the metal after it is cleaned up down to the base metal.
I was a diesel mechanic for 18 years of my life (mostly not trucks) and I have seen all manner of repairs done on coolant systems. I have seen people patch up a small hole in a radiators with regular soft solder. Of course, with the later aluminum radiators you need something different.
Of course, the best fix is replacement with a new part. But those new parts are often NLA.
