For anyone interested:

Supplement 6 – Repair Welding and Fabrication Welding of Carbon and Low Alloy Steel Castings

Supplement 7 – Welding of High Alloy Castings

Can be downloaded free at the link below. Pretty exhaustive info on steel casting welding repair. Some of the editing of the texts is not so good but lots of good information and welding procedures in both texts.
