Dear All,

Welding Process -GTAW+SMAW

PQR Thickens is 25.4mm

And Material is A106 Gr.B My query is as below -

1) For Sour Service what are the test we required and what is the minimum and  maximum thickness qualification for WPS.

 

    same as per ASME-IX,or else specify in your Client spec. check PWHT.

 

 a) What is the Base metal thickness Range and  Deposited weld metal range as per B31.3 for GTAW & B31.4 for SMAW.

       t/2 to t+6mm,  12.7mm to 31.4mm 

 b) As Per ARAMCO & Sec IX- AWS No(Class) ER 70S-2 / 3 can we use in WPS . but in PQR they have used only ER70S-6

     ER70S-3 is recommended. 

Please looking your favorable reply on my query with  standards. 

Thanks and Regards

Kiran
