Your biggest problem is with that self shielded wire. To my knowledge it is meant for light duty hobby use and will not produce a full strength weld. If you could find a old welder that will let you do stick welding. Also if you do get a CC power source (stick or tig) you can get a kit to allow you to tig welding. Both ways would be better. I tried stick welding without a preheat and had some problems with the weld breaking especially when I used 6010. Whenever you just go and weld on top of a old broken weld you can't really expect to get great results. I guess the one thing you can try is to increase surface area of the "weld".
If you find something that ends up working let us know what it was.
Hey I didn't mean to start anything just provide some basics. You are correct that perhaps I over simplified. Do you know what the actual wire is that you are using? When I it looked up i found this https://m.harborfreight.com/0030-in-e71t-gs-flux-core-welding-wire-200-lb-roll-63496.html?utm_referrer=direct/not providedThat is not a true statement, however a lot of people recognize it as that as they see it as the inexpensive way to mig weld without the need for an external gas source and regulators. It's 'general' purpose is for use in an environment that is not conducive to using a shielding gas that would otherwise be blown away from the welding area by wind. Try using an unshielded wire shielded with gas in a windy environment. It'll be one of the nastiest welds you've ever seen.
I've repaired suspension parts and hitch parts of class 8 trucks with self self shielding wire that are still in service. The biggest factors I see in weld failures from the use of self shielding wire are inadequate power, inadequate skill, and inadequate cleanliness and with adequate power you can pretty much overcome the other two. Another factor is wire. I've used parair's prostar line, lincoln, victor and a couple others and believe it or not the best I have used so far is the HF .030 flux cored.

No, the two halves just popped apart after a bit of heat and a tap with a cold cut chisel.Is that not just left over from where they did stick?
I may be able to grind past it I am just afraid that every layer has this sort of incomplete weld.I’m assuming that’s flat on the face of the layers and not the bias. If so, even if that’s not just where it did stick like kuraki said, my guess is you can grind past it.
At some point you're going to have to make the decision on when to start over. I'd grind past to see if you can get past this area and re-forge weld. It may be that this is throughout, and you may only find that out when doing the grinding on the blade, but instead of calling it a loss, consider it as learning.I may be able to grind past it I am just afraid that every layer has this sort of incomplete weld.
Depends on what the result of the above is. If it's throughout the billet, then it's probably something you did sub-optimally. If this is the only spot, then it's hard for me to say. I've read that occasionally 15N20 from saw blades can have flaws causing blisters during forge welding.I was able to pry apart one of the thin sections of one of the layers and underneath was a clean, but separate surface. Any clue what may have caused this?
