ASME IX WPS Filler Metal Claridication
ASME IX WPS Filler Metal Claridication
(OP)
Good day,
I have a WPS that is a F3/F4 welding procedure (E6010 Root/E7018 Fill and Cap). Understanding that filler metal is an essential variable; does that also mean that one can not use this procedure when welding a F3 root and an F3 Fill and Cap. I have been asked if it is ok to use this procedure for a E8010 for the fill and cap.
Thanks!

Hi BGinBC,
More information is needed to comletely answer the question.
The primary limiting factor will be the E6010 maximum qualified thickness as based upon the relevant PQR(per ASME Section IX , QW 451.1). So if your WPS is qualified with a maximum 0.125" E6010, that is the limit for that electrode. Additionally, if your WPS specifies E6010 root, remainder E7018, you will be limited by that as well.
Getting past the code issues, with all things being equal, the welds's mechanical properties (toughness, significantly) for what would be presumed to be an all cellulosic weld will be inferior to that made with E6010/E8018.

While a welder, similarly qualified with F3 root and F4 fill is qualiiied to weld completely with F3 electrode. The WPS is not so qualified.
