Question about San Mai, may be crazy

Hey all, I have a question here, and this may just be my stupid showing, but I wanted to know what you guys thought. I have done a bit of forge welding, and am interested in doing a laminate. My stupid question is that for an oxygen free forge weld, is it possible to lay up the three pieces, and complete weld around the edge? This would eliminate new oxygen, but my concern is whether or not oxides and junk would form between layers from the mig weld itself. I am interested in in doing a core of 1084 or 1095 or similar, between wrought, 15n20, and possibly a stainless such as 416 or 420. These are the three laminates that I have been considering. I may try the kerosene, but I doubt that would work well for hammering, so would have to wait until I was at my buddies who has a large press and rolling mill. I am mostly interested in doing a laminate by hand so I imagine the stainless skin is out. Just wanted to know what my best Orion was for a hand welded billet and if my strange thought was even viable. Thanks in advance everyone.
 
I've cheated before and tried something similar... I ran stainless weld beads down A36 stock, ground them down smooth, stacked them, and welded three side rather than completely boxing them in... The forge weld stuck but I have not been back to do anything with that billet as of yet.

Trying new things out is never a bad thing, it's how we discover new patterns, textures, etc... Take that with a grain of salt because I'm more artsy fartsy and have no idea how conducive the method is regarding blades.
 
Forge welding simple carbon steels together is an entirely different animal than welding stainless to carbon.
15N20 and 1095 will stick together just by putting them in the same room. :p

I've done it with 15N20 and 1095. Worked great.

Lots of guys weld the entire perimeter of the three pieces.
You just can't have any oxides between the pieces.
Wherever there are oxides - it won't weld.

 
No one has explained where the boron goes ! We have steels that have small amounts of boron added and this raises hardenability quite a bit !
