Want to weld my housing to my differential and am getting conflicting info on whether the housing is cast steel or iron. Any advice on how others do it?
It will weld, however you create a brittle part or structure if it not pre/post heated correctly. That's why the above is done.The center section is nodular iron,
The correct way to weld nodular iron is to heat the center section to 600'f and keep it there while running the bead.
After finishing, heat the center section to 1000 to re-nodular the welded areas, then wrap the section in heat blankets and let it cool.
That's the way mine was welded by a NASCAR fabricator and it's held up to hundred's of 6000rpm clutch dumps on slicks...
