Welder Qualification Criteria
Welder Qualification Criteria
(OP)
Background: A welder has deposited E 7018 (F4) electrode on a 6"Ø X Sch 40 test coupon with backing. According to
QW-452.1(b), this welder is qualified to use F4 electrodes up to 14.22mm with backing.
According to QW-433, this welder is also qualified to use F1, F2 & F3 with backing.
Question: If a production joint having 14.22 mm thickness with backing strip is to be deposited using E7024 (F1), E6013 (F2) & E6010 (F3) electrodes, do we have to re-qualify the above welder in all the three F numbers individually?
Thanks & best regards

Reply; No. See QW-353 in Article 2 and QW-404.15 in Article IV in the 2007 Edition of ASME B&PV Code, Section IX.
