[MW:13545] Maraing steel with eutectoid steel

Hi all,

We are trying to weld 300 grade maraging steel with eutecoid steel.
I tried to find some welding literature on this two steel, but no one has done it.

I like to know,
##   What will be the welding parameters to have a good weld deposit.  ##
##  What preheat temperature ##
## What inter-run temperature have to be maintained ##
## If you send some link related to it, then it help me out. ##


welding dimension : 70mm in length , 20mm wedth, and 15 mm depth.
