I'm sure it worked, Airin! (Plus I've already seen the preview LOL). Looks good! One note, be careful with that copper that came out. I had some leak out of a cu-mai billet and then I found it later embedded in a damascus billet I was doing and had to grind it out. Check your forge after and remove any little beads so you don't get them embedded in future projects.

Ya I saw the beads in there and if you don't get em quick they hold on real tight and almost have to chip them out! But you can't move them around when they are liquid either! Kinda reminds me of mercury

I think so! As long as the melting point is highr than the temperature needed to heat treat the steel. I know brass melts at an even lower temp than copper. 1084 needs around 1500 degrees to heat treat. Copper melts around 1900 degrees and I believe brass is somewhere in between those 2

I would have thought that you would need to heat treat the welded billet prior to profiling. I’d have to check the temps but I figured the copper would melt again during the heat treat and the layers would separate. I guess we will see next video.

Thus steel heat treats at roughly 1500 degrees and the copper melts at 1900 roughly.

The copper isn't going to be at melting temperature during the heat treat. It's only above 1900 when forge welding. Heat treat was probably be around 1500.
