[MW:3917] WPS & PQR clarification

Dear Group

 

 Good day,

--------------------------------------------------------------------------------------------------------------------------------

Still I have confusion on WPS and PQR terms.

 

1. WPS to be created  first , with respect to  selection of process, electrode and current  etc.

2. PQR is developed  after WPS ,by entering the the actual variation  relevant to the WPS.

 

|Corresponding reference numbers are to be entered  in each other.

 

This is the information  from ASME IX codes.

 --------------------------------------------------------------------------------------------------------------------------

But there is a controvercial  statement  from some of our colleques, PQR to be developed first and  Supporiting PQR  reference number is to be entered in the WPS.

 

Please clarify this confusion .
