Cast Iron Car block tig welded

[blasphemy000]

What kind of engine was it that it was rare enough to warrant this type of repair instead of just replacing the block?

Well, it's a deep skirt block, but doesn't look like a mopar, maybe a Ford FE series or similar? S/F....Ken M

Nice repair. It sounds and looks like a low expansion, high nickel content rod. Any nickel-iron allloy where the nickel reaches or exceeds mid 30's %, the low expansion "magic" starts to happen: http://en.wikipedia.org/wiki/Invar

I've had good results with it as well (a 55% nickel / 45% iron stick electrode, with the flux knocked off, and applied via TIG), but sometimes the cast iron can get a little cruddy. Interested in hearing how you prepped the cast iron because you got a nice result.

Did you weld both sides one pass each (2 passes total)? Or try to it is in 1 pass? Did you manage 1 continuous weld bead or did you beak it up? Did you skip around or "stitch weld"?

Welded continuous just tacked it and then started welding.

I would be surprised if the iron doesn't crack right next to the weld once it gets back in operation.

They pay I weld don't ask questions I think it was a Land Rover engine.
