Quadrafire 7100 cracked rear channel

[Mjamesb]

I have read through the forums but didn’t find an answer. This photo is rear channel. Can this be welded? Is it dangerous or just less efficient? This unit is built in so to replace I have to tear out all the stone work etc. I have absolutely loved this unit over the years. I need a fire to mentally survive winter 😆

Unfortunately, it looks like that area has been leaking for a while. It might be possible to weld a plate over that area or at least patch with a high-temp epoxy and a stainless plate bolted across it, to buy some time.

@bholler, does Quad have a patch kit for servicing this?
