Re: [MW:20374] WPQ COMBINATION

 Dear Rajesh,

As per My Knowledge

No, 

Because, 

Your welder A cannot weld below 73 mm OD.

Also both of your welder cannot deposit maximum because during initial qualification they not deposit at least 13 mm with  three layers  to qualify for maximum deposition.

Thanks

Regards

Ansari

Thanks

Welder A:
First WPQ
Qualification test coupon: 168 OD X 18.26 mm
Welding Process: GTAW + SMAW
Deposition Qualn Range: GTAW = 8 mm, SMAW = Max to be welded.
Welding Position: 5G
Position Qualn Range: F, V, O

Second WPQ
Qualification test coupon: 63.5 OD X 6.35 mm
Welding Process: GTAW + SMAW
Deposition Qualn Range: GTAW = 4 mm, SMAW = 8.7.
Welding Position: 6G
Position Qualn Range: All

Welder qualification as per ASME sec IX

Can these two qualifications be combined as below:
Qualification min OD: 25 mm
Welding Process: GTAW + SMAW
Deposition Qualn Range: GTAW = 8 mm, SMAW = Max to be welded.
Position Qualn Range: All

Please suggest.
