Head of Technical Inspection Team

G'day Sir,

I hope everything goes well. I'm involved with an oil fields development project in south of Iran as Third Party Inspection Agency, recently the main subcontractor has sent us laboratory results of a PQR which has been prepared for supporting two WPS's. The first WPS is:GTAW+SMAW(ER-70S-6+E-7018), and the other one is: SMAW+SMAW(E-6010+E-7018). It's worth to mentioning that above PQR has been prepared by first WPS i.e. GTAW+SMAW, and wall thichness of test pieces is 10.97mm, and the base metal is ASTM A106-B, now the question is: Will so prepared PQR support both above mentioned WPS's?

I am looking forward to hearing from you.

Yours,

Mohsen Behzadi
