Finally got my forge welds to hold after 8 months of trying
I've been hammering away at this little coal forge in my backyard shed for about 8 months now, and forge welding was just kicking my butt every single time. Last Tuesday I had a pile of scrap rebar sitting there and decided to give it one more go after watching a guy on YouTube talk about flux temp. I cleaned the metal super well with a wire brush, got it up to a pale yellow in a good part of the fire, and tried a lighter hammer blow than I usually do. The weld actually stuck on the first try, no delamination or anything! I pulled it out and it held together under a bend test, which I've never had happen before. It's just a simple stack of three pieces but for me that's a huge step forward. Has anyone else struggled with getting the right heat color for forge welding, or did you have a trick that finally made it click for you?
