(OP)
I am looking for code reference to weld repair a cast body according to ASME code. UW-38 doesn't list anything like what would be considered major or minor like in TP278 (MIL-STD) Can anyone help me out.

You have got to be kidding. This is routinely done on pressure retaining castings in most major fabrication shops.

As Metengr states, Section VIII is a good reference for repairs. Weld procedure qualification is no different for repairs per ASME IX than fabrication welding, with the possible exception of temper bead welding, which is often used for repairs, but can be used for fabrication as well. The only definitions for commercial casting repiar sizes are in the ASTM material specification, but a field repair would not need to comply with the ASTM specification, but it would be a good guideline.

To repair major damages on casting can be catastrophic as you are all aware that casting is far from being a perfect material--better eer on the cautious side than the frugal side.
