I assume an arc welder will be used to repair. Heat the area with a torch, not cherry red tho. Just get it hot enuf short of color change and then apply the arc welder. Note that the arc welder will make for a hard fill and maybde difficult to drill. Use a carbon rod or sha[ped block to fill / sculpt the hole to redure drilling/filing to finsih.

But like u say it's always a crap shoot. Sometimes it works just fine other times not.
