Following is example to explain the conditions

 Condition 1

As per manufacturer (Say manufacturer ABC) the Flux and Wire combination mentioned on the data sheet and bag of flux is F7A8-EH12K and is inline with the ASME Sec II Part C SFA 5.17

Where "A" is as welded condition

PQR was qualified with PWHT using above mentioned manufacturers flux wire combination.

Question

1.       Can I write on my PQR and WPS write the Flux wire classification as F7P8-EH12K - NO FLUX-WIRE combination welding consumables shall be Qualified by Welding consumable Manufacturer. See below portions of ASME Sec.IIC.

2.       Batch of flux and wire used in PQR shall only be used in Production welding. - NO RESTRICTION in Code

 

Condition 2

I use a Flux from manufacturer ABC and wire from manufacturer XYZ. Manufacturer ABC who is the manufacturer of Flux has certified the flux on bag as F7A8-EH12K (when I say this, I mean the manufacturer ABC has used both flux and wire from manufacturer ABC)

 

My actual conditions are I am using different manufactures for flux and wire to qualify PQR

PQR was qualified with PWHT

Question

1.       Can I use different manufacturer for flux and wire - NO Code restrictions unless specifically restricted in the Specification

2.       Can I write on my PQR and WPS write the Flux wire classification as F7P8-EH12K - NO

3.       Batch of flux and wire used in PQR shall only be used in Production welding. _ NO

 

Appreciate your advice for me to understand and if any reference document which I can review of the subject to clarify.
