Ok,sorry it took so long. I finally got a chance to do some work on it. I milled out each side with a 3/4" ball end mill. Then cut a slot ware the crack was. I tried mig on the inside first and that failed to bond well so I had to mill it all out again. I used 7018 and that worked much better. I still have to heat the hole area to get it to relax before I test it out. I have some picks of the steps. Wrought Is it's own animal. Machines very easily though. I want to thank every one for helping me. It would not have come out as well as it did ,thank you !!!

Thanks every one. I will post pics , but I ran into a slight snag, this thing was coated in so much grease fore a very long time. I keep cleaning and grease keeps pouring out. I gotta make sure when I prep it that it's not going to get contaminated before I weld it. Grease also keeps pouring out of the crack.

Thanks, I'm going to clamp it in the mill at lunch tomorrow and drill down with a 3/4" ball end mill. Making a half circle relief on each side of the crack. )( I'll try a 6010 root and follow up with the 7018. I will preheat and post heat the hole area after. Should I post heat both sides of the opening to get the hole thing to stress relieve. I mean the side that didn't crack.

Thanks, I would love to weld this and feel confident that all would be good but I have bin reading bad things about welding wrought. I can oxy aceteline weld, stick,tig,and mig. It's in a bad place and I don't want to make a bad situation worse with out checking with people who have structurally welded wrought iron. If it was hot rolled steel I would feel confident in the repair.

Thanks ,the mig gas was the tri gas. The real problem was the wire. It was corona weld 321 ,designed off all mild steel but it's a maintenance rod. Good for galvanize with out cleaning. Paint and oily metal. It try's to float everything to the top. The weld looked like a sponge. You guys warned me about not using a deep burning rod so I switched to stick 7018. The welds are so big because I used 5/32" rod. A big hole to fill
