Dear Sirs ,
I would like confirm from you ,
for instance, for the A 516 Gr.70, A-105, A-106 Gr. B ( P No.1 ) materials, we usually use AWS Class E71T-1C, SFA 5.20 for FCAW process in our shop and we have also qualified last year as per ASME-Sec IX using 2017 Ed for P No. 1 with PWHT and without Impact test conditions.
My question is, under what stage and circumstances we opt for SFA 5.36 FCAW and why do we use instead of SFA 5.20 ?
If qualified using SFA 5.20 AWS E71T-IC for P No. 1 with PWHT and without impact test, can I rewrite the WPS with SFA 5.36 , AWS E71T1-C1A0-CS1 for NO Impact Test condition, if I have FCAW stock with AWS E71T1-C1A0-CS1 .
Please advise.
Regards,
Saravanan Sornam,
Pyeongtaek,
Korea.
