If it isn't fabricated then it is still raw material, is weld repair of this material allowed?

Procedures do not make welds, and neither do codes.

ASTM A266 (carbon steel forging) says this about repair welding -

9. Repair Welding
9.1 Repair welding of forgings is permissible only at the
option of the purchaser. If repair welding is performed, welders
and weld procedures shall be qualified in accordance with
Section IX of the ASME Boiler and Pressure Vessel Code.

TMoose,
Are you saying 'read the material specification'?

Hi Ironic,

Yes.

But I proposed something similar in alisharif's double post in some other ET forum.
Here we may well have a language complication, in which cases I am sometimes willing to try to "prime the pump" a bit rather than resort immediately to applications of "the stick."

Also, yes, I enjoy mixing metaphors.
