I need a WPS for mig welding by 80S D2 1.2mm solid wire for welding of En 24 to MS plates. Can anybody help me out?

Do you need a procedure[paper work] or just how to go about welding it? Or both.
Reason I'm asking is if you want a wps to make this legal[sorta speaking],you'll have to weld up a test coupon and do a procedure qual. on it and thats what you write your procedure spec to,generally speaking,there could be a couple of exceptions.
If you just wanta know how to go about welding it,,you might need to give a little more info,,I'm not sure what two materials your talking about welding,en24 to ms plates,would that be en24 to mild steel plates? I'm not familar with en24,,what is it chrome,nickle or what kinda steel is it.
There are numbers,that id material,asme,uns,p numbers type or grade,for instance,sa-106 pipe has a grade of either a,b,or c,and different uns numbers and is a p-1 material,and might be even in group 1 or 2,,so right there you know its just carbon steel,about any 60 or 70 series filler will work,preheat maybe 50 degrees,no post heat treatment,,,
Maybe somebody is used to dealing with en24 and can help,this must not be in usa cause you say mm,which can futher confuse this,[different specs etc,,],thingy

I think MIKIEweld would be best qualified to answer this question...material identification doesn't translate well across the pond.

EN 24 is an old standard. The current British standard BS970 is 817M40 . This is equivalent to AISI/SAE 4340
That said, its impossible to determine the variables in you WPS without more info such as thickness ( determine preheat and interpass and WFS ) and joint design ( determine # of passes , WFS etc )
Is this weldment going for stress relieving after ?
