Hi!
For Monel NiCu7 overlay on CS/LAS no need of any barrier layer you can directly weld NiCu7 on
CS/LAS base as it is comparable while as CuNi7( Cupronickel) is not comparable with CS/LAS) so not recommended to use as barrier layer
Ni1 is used as barrier layer for Monel overlay on CS/LAS for thiner base metal/nozzle pipe to avoid effect of dilution where Fe to be controlled below 2% in undiluted chemistry at closer to the fusion line as possible

Due to Fe content problem, whether, it will be better to use ER Cu Ni deposit as barrier layer and then weld deposition with ERNiCu7 ?
