change in electrode class
pankaj...@wipro.com
Dear all,
If the procedure is qualified on E7018 Electrode for SA 516 Gr 70 then can we use this WPS/PQR for welding IS2062 Gr B by E6013 electrode. Also for welder qualification can we use this WPS/PQR , Give code reference
I think change in filler metal class is essential variable.

If you are using ASME SEC IX 2010 then you can not use.
For SMAW Process F number is Essential Variable for welding procedure
qualification and F Number of E6013 is 2 and F number of E7018 is 4.
And for welder qualification F number also essential variable. So you
can not use different F number.

Remember that E-7018 is F4 and 6013 is F3, In procedure is essencial variable.But in performance welder there is not problem

Dearr sir,
But my question is
I have a qualified WPS/PQR for P1 G1 with E7018 Electrode and another welder is qualified with same electrode.
Now can another welder qualified with E7018 can weld IS 2062 with E6013 electrode?
Can I offer this WPS/PQR of E7018 to TPI for this E6013 welding.

WPS may not be used as indicated.
Per QW-253, F-no is an essential variable for SMAW procedure qualification, i.e. QW-404.4 applies. E7018 is F4 while E6013 is an F2. Therefore a PQR using an F4 electrode cannot support a WPS using an F2 electrode or vice versa.
As long as impacts are not required, base metal would not be an issue since 2011a Section IX QW/QB-422 recognizes SA/IS 2062 E250 B as a P-No. 1, G-No. 1 material. If impact testing was required the
With respect to weldor performance qualification. {Assuming you had a properly qualified WPS for F2, F3, or F4 electrodes.} The weldor could use either F2, F3, or F4 electrodes and be qualified for welding with F2 electrodes per QW-433.

Your last statement regarding welder qualification is incorrect. Please
look at QW-433 "Alternate F-Numbers for Welder Performance
Qualification", which specifically addresses SMAW.
Qualification with F4 will additionally qualify the weldor for F3, F2,
and F1.
Qualification with F3 will additionally qualify the weldor for F2, and
F1
Qualification with F2 will additionally qualify the weldor for F1

I agree, i was incorrect about welder qualification.
actually i was confused with f-6..
thanks
yes welder can weld.

Per QW-433
A weldor who successfully completes weld testing with F4 electrodes and backing is qualified to weld, with backing F4, F3, F2, and F1.
A weldor who successfully completes weld testing with F4 electrodes without backing is qualified to weld F4 with or without backing, and F3, F2 and F1 with backing.
Practically, I would not allow welding with F4, F3, or F2 without backing (open root, full penetration) in any case. Nearly all weldors will make a hash of production welds without backing with electrodes of these classes.

Root pass can be considered as backing for fill passes?
A welder qualified to F4 can make fill pass with F3, F2 or F1, without furter qualification?

Yes. If qualified with F4, the weldor is qualified to make fill passes with F4, F3, F2 or F1 electrodes.
In our shop, typically, open root welds will be made with a GTAW root pass (sometimes GMAW) and fill passes made with another process; in the case presently being considered, SMAW. The weldor would be qualified without backing, with F6 filler metal for the GTAW. For the fill passes the weldor would be qualified with backing (usually back gouging & back welding the root) and F4.
Some may qualify for open root with F3 electrodes (e.g., E6010, E6011) for the root pass and fill with F4, similar to the above.
Section IX considers welding with backing as either: (1) welding with a physical backing strip placed at the root of the weld or (2) back gouging the root to sound metal and then welding the backside.
