Hi Metallurgy_eng
Sorry, ignore my comment
Quote:WALLEX 42 SA I believe is a NiCrBSi self fluxing alloy, so a little puzzled by your reference to Metco 45C and CoCrW.
I have no experience with this particular powder, and can find no information on particle size. Being forced to choose a set of parameters as a starting point, I would go with Metco 16C or Metco 43C.
My search earlier "WALLEX 42 SA" found only Colmonoy 42 SA (Wall Colmonoy website was down at that time, ok now) I was too hurried to notice Colmonoy (NiCr based) was not Wallex (CoCr based). Sorry, obviously in need of coffee
I could only find reference to Wallex 40
So, Yes I would select Metco 45C parameters as starting point, though these products Metco 45C (CoCrNiW), Stellite 6 (CoCrW) and Wallex 40 (CoNiCrBSi, I'm guessing similar to Wallex 42) are similar in that they are cobalt based alloys, but they do differ somewhat in composition, so I would not necessarily regard them as equivalents.
I think my other comments are still valid.
