hi everyone.

does anyone know what filler rod to use when welding a cast iron turbocharger housing to a 1018 cold rolled v-band flange? does the housing need to be pre-heated before it is welded?

here's an example


thanks

RE: Turbine Housing TIG welding filler material ?

When joining 1018 to Cast Iron--assumming a weldable grade, use RN-61 filler--but pre-clean cast iron by heating to dull red and wire brushing-----then preheat cast iron up to between 700 -1000 F and butter the cast iron in the area of attachment to the 1018 with at least 3/16" thickness of RN-61.  You may have to provide for undercutting the cast iron for dimensional purposes to accomodate the buttering layer thickness.  You may either then complete the joint to the 1018 using the RN-61 at the elevated temperature or after a slow cool (wrap insulation)around the welded cast iron-----do not weld the cast iron to the 1018----it is preferable to weld the RN-61 to the 1018---this is the reason for the buttering layer.
