I have never seen a rotor housing have TIG welds. Does anyone know why they would do such a thing? This came off j-spec twin turbo. The center iron also has unusual writing on it also.

If I were to take a guess, when they make rotor housings, they don't make them one at a time. They are probably all welded together in a couple spots, run down a line, and when they are finished are cut apart, that one was probably just one on the end

course I could be breathing some very funny dow air and it making me think loopy

insightful

the castings are never perfect and they do welding to repair some of the hollow areas.

i often wonder how many brand new housings actually wind up in the scrap pile and need to be totally recast because i see welds on them quite often.
