Dear Kundan/Mayur,



ASME Section IX Welder Qualification related Question.



As mentioned in section IX for qualification of welder or welding
operator use qualified WPS with supporting PQR's, if our PQR is welded
with P No- 8 to P No-8 (SA 240 TP 316L TO SA 240 TP 316L).

Is it possible to make WPS with P No-1 to P no-1 (PQR is with P No -8
To P No-8)  but other than p no  all variable are same as used in PQR
(Like filler wire, shelding  gas, purging if require or etc), this WPS
will use only for welder qualification. please guide us.
