API 582 wrong filler in Table A.4

  1. inspectormag
    Hi friends,
    today my friend asked me a filler for Cu-Ni (90-10) and I recommended him to use API 582 Table A.4 but I found a wrong filler in the table and I surprised really.
    According to AWS A5.7 the filler for Cu-Ni (90-10) is ERCuNi but as it is recommended in table A.4 of API 582 the filler should be A5.11 (ERNiCu-7).
    As you see it is wrong filler while material is Cupper based and the filler should be a Cupper based also.
    Who can confirm me?
