My flea market anvil pretty has no good edges, so I made an anvil block by welding square mild steel bar for the hardy hole to a hardened steel bench block I had laying around. Predictably, the weld failed after a few dozen strikes. Internet research says I should anneal the hardened steel, weld, then harden again. I have no idea what kind of steel it is, and I don't have the tools to anneal properly, but I figure I could at least normalize it. Do I need to try to harden it again after I weld it, or will the normalized steel be adequate? I don't have experience hardening, and I'm not sure it would fit in my forge.
Thanks
