Re: [MW:32032] Welder qualification

1. CuNi - 12.7 mm thickness  -  Not permitted 

    Reason - 

    F NO  34 - Welder qualified up to 11.08  mm only .

    Maximum metal qualified  is qualified using F NO 6  filler wire  and NOT with F NO 34 

2. CS - 1" OD -  Not permitted

    Reason - 

     Welder qualified  from   OD 73 mm   and above  with F NO 6 .

      So P NO 1  + 1 "  OD  using F NO 6  filler wire is not permitted 

  F NO of one qualification  and   diameter  of other qualifications can not be  considered for production welding.

2. GTAW+SMAW - OD - 2 7/8 Inch, Thickness - unmimited, P No. 1, F no. 6.

Now my doubt is
