Can anyone identify the sheet metal of the combustion chamber? (Iconel? Monel? SS?)
What weld process was used? Was a rotating fixturing jig used, I assume?

Hi,
I do "hot section" and tail pipe repairs on the J-47 engine used in the North American F-86 Saber. We have several customers around the world, that we do this for. On the earlier engine, the inner and outer combustion cans are made from 347s.s. On later engines, the inner cans are made out of inconel and the outer cans are still 347 s.s.
I can post pictures, if anyone is interested.
