[MW:18849] OVERLAY CHEMISTRY

 i am preparing PQR for overlay with the following on SA516 GR 70

 

 

 1)DUPLEX E2209  (SMAW 3.15 dia)

 2) INCONEL ERNiCr-3       (MIG 1.2dia solid wire)

3) MONEL ERNICU-7 + ERCUNI (MIG 1.2 dia sloid wire)

4) DUPLEX ER2209 (MIG 1.2 dia solid wire)

 my question is 

1) is the pure chemistry of filler(consumable) must for qualifying CORROSION RESISTANT OVERLAY PQR

2) at what HEIGHT from base metal can I expect to get pure chemistry for above all consumable?

regards 

vinod
