Welding CPM M4 and M2

[Storm W]

I know I just asked this question about welding stainless but M steels are really complicated. What would you have to do to be successful welding on tangs? I do have some inco 625.

Narrow or full tang?

Narrow.
I will be sending the blades to @Willie71 for heat treatment.

Use mild steel or 410/416 for the tang, mig weld, preheat to ~400f, after full penetration weld, post heat to very dull red 2-3 times. All welding should be done before heat treating.
