P1 no Range

[sn vl]

Hi..

How to find in ASME sec IX P no to Pno qualification range.
Eg : If a welder qualified for P1to P1
what is the Range qualified As per Sec IX.
Where is given in CODE.


Regards
SN.

Dear sn vl,

The base metal qualification range for welding performance
qualifications are stated by QW-350s tables (i.e., QW-353 for SMAW).
These tables lead you to article QW-403.18 which says: "A change from
one P-Number to any other P-Number or to a base metal not listed in
table QW/QB-422, except as permitted in QW-423, and in QW-420.2."

According to QW-423, "when a base metal shown in the left column is
used for welder qualification, the welder is qualified to weld all
combinations of base metals shown in the right column":

BAse metal for welder qualfication:
P Nº 1 to 15E or 34 and 41 to 49 (note that 2010 version has reasigned
5B.2 group material as 15E.1 and that S numbers have been reasined as
P numbers).

Qualfied Production Base Metals:
P Nº 1 to 15E or 34 and 41 to 49

Therefore, if the qualification test was performed for P1 to P1, the
qualification range will be P Nº 1-15E, 34, 41-49.

IS 2062 is an unlisted material

SS 410 will under P number 6 ( refer table QW/QB 422)

[jaya anil]

Dear Puneet,

 

IS 2062 Gr A, is unlisted , but max. properties were equalent to P1. but while preparing WPS/PQR use Material Spec as IS 2062 GrA .

 

SS 410 is Martensitic Steels, its P No is 6

[puneet takiar]

Dear Colleagues,

Can anybody help me in describing method to select Electrode for welding SS to M.S ( IS2062 Gr.A to SS 410).

As per sextion IX table QW 442, A no. will be 6 ( is it ok) and how i can find F no. w.r.t A no. whether there is any coorelation of A no. with F no. or not? OR their function is different w.r.to each other. please help.

 

If  the F no. is to be selected by experience then how the table of F no. in QW 432 is helpful.

 

Warm regards, 

puneet takiar

First You have to select the suitable Electrode/Filler Rod from your experience or based on Technical Literature.   The suitable electrode for welding IS2062 Gr.A to SS 410 is either E309L or Nickel based consumables like ENiCrMo3/E NiCrFe2/3.   Then check for the A.No in QW-442 as A8 for E309L & A4X for Nickel based electrodes   Then based on the SFA number(obtained from Sec.IIC) for the particular electrode, F number can be determined like F5 for E309L etc...
