Its very difficult to achive the stip chemical chemistry by single
layer cladding due to the dilution of the base metal.
during welding you are forming a cast, which have chemistry like a
casting, then as u said, u have taken the CA 3 mm away from the fusion
line, this will not help you as u required.
You may consult the supplier for a strip electrode, which can produce
a required chemistry as per standard requirement with combination of
flux.
