Want to see how I've expoxied a cracked radiator?

What do you think? Will it hold?

I doubt it. The metal will expand and contract and there is pressure on the
epoxy. Might buy you a few days, but welding is the proper cure.

Call it weld if you like, but I think brazing would be the proper term.

Suggest the OP might try asking in rec.crafts.metalworking if his epoxy
repair fails.

Epoxy , no , Solder mayby , Brazing - welding yes

The time spent on Dan's site can be a lot better than asking here.

of the way down.

No. Brazing might be better, welding with nickel rod will work best and is much
faster to do. HTH

there's lots of different types of epoxy. i'd use marinetex if i had to use
epoxy, which is good enough to use on engine manifolds.

But an engine manifold has a vacuum, not pressure. This says it is for dry
environments.

Up to what temperature can Marine-Tex be used?

Depends on pressure and conditions, up to 250°F constant temperature, spikes
up to 300-325°F in dry environments.





This is not suitable either because of temperature.



Can I apply FlexSet to a repair that is submerged in water?
Yes. FlexSet has an amazing ability to almost push the water aside so that
it bonds directly to the repair surface. The attraction of the FlexSet to
the repair area increases as the material reaches full cure (24 hours in
72°F)

What temperatures can FlexSet withstand?
Once fully cured, FlexSet can withstand temperatures from -40°F to 100°F.

I don't mean to argue, I was just wondering.

However, I once repaired the water jacket in an aluminum manifold,
during wintertime and while the manifold was on the car. The crack was
on a rounded section and appeared to curve out of sight. JB Weld held
and the leak was gone for as long as I owned the car. Just a story,
from personal experience.

The radiator is now connected and I am going to observe it for a few
days. Who knows...

Yeah, right. I'd like to see you weld cast iron.

Idiot.

I assume the word "Idiot" is your signature, not something you are calling
others. Please educate yourself, Mr. Idiot, so you don't look silly.

Weldability
This depends on microstructure and mechanical properties. For example, grey
cast iron is inherently brittle and often cannot withstand stresses set up
by a cooling weld. As the lack of ductility is caused by the coarse graphite
flakes, the graphite clusters in malleable irons, and the nodular graphite
in SG irons, give significantly higher ductility which improves the
weldability.

The weldability may be lessened by the formation of hard and brittle
microstructures in the heat affected zone (HAZ), consisting of iron carbides
and martensite. As nodular and malleable irons are less likely to form
martensite, they are more readily weldable, particularly if the ferrite
content is high.

Thanks for proving my point!

No, I proved it can be welded, albeit with some care needed, You sait NO.
