[MW:15008] RE: change in electrode class

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.

Pankaj

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.

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.
