Can this be done with a safe result? There is a 4" crack running up from the lower left corner of a heat exchanger on a stand alone Empire furnace. I want to be safe but if it can be done safely I may contact someone to do it.
Thanks for any replies

Welding a Heat Exchanger

Welding cast iron is possible, but requires certain skill and the right equipment. Unless you are a skilled welder, I suspect it would cost you almost as much to have it repaired, as to just get a new furnace.
Molo, here is a link to an article on welding cast iron. After reading it, I think you may agree that it may not be a worthwhile venture for your problem.

OK, Thanks for the responses. It doesn't sound like a good idea. Why do they make them so thin? This is an Empire that isn't that old and it's cracked!

How old?Originally Posted by molo
How did you discover the crack?
Does your furnace have a flame rollout switch?
It might be 10 years old. It is a vented stand-alone furnace about 3' high and 4' wide. We noticed the crack during a cleaning and inspection. I do not know if it has a flame rollout and I know this heater has been used with this crack.
