From PQR done with E6010(FN 3) as root and E7018 as Hot pass and
capping, can we form WPS with root, hot pass and capping as E7018???
From ASME Sec IX it is clearly given that F Nr.4(E7018) Qualified wth
backing is not qualified to carry out without backing.
In double V grove welding can I form this WPS?? Since the welding on
the second side is provided with backing by the first side weld.??
Regards
Akhil
