Most of you probably know this, but there was a repair station at the Tonawanda Foundry for cosmetic welds on cast iron parts. These repairs could only be done on non-stress areas though. The repairman just heated the damaged area to cherry red with a torch - then welded the damaged area - then covered the repair with asbestos cloth. They left the asbestos on until the next day before grinding the repaired area smooth. Most of the repairs involved chipped valve cover rails on heads and intake mating surfaces on the front and back of blocks.
