CWI WPS and PQR Qualification 2

Question 1

Under ASME Section IX, a change in base metal P-Number from P-1 to P-3 is considered what type of variable for a groove weld WPS?

Accepted Answer

Essential variable

Answer

A change in P-Number is an essential variable under ASME Section IX, requiring requalification of the WPS.

Question 2

In ASME Section IX, filler metals are grouped into F-Numbers primarily to reduce the number of:

Accepted Answer

PQRs required for similar materials

Answer

F-Numbers group filler metals with similar usability characteristics so that qualification with one filler qualifies others in the same F-Number group.

Question 3

Which of the following is NOT recorded on a Procedure Qualification Record (PQR)?

Accepted Answer

Welder's name and identification

Answer

The PQR records the actual welding conditions used; the welder's identity is tracked on a Welder Performance Qualification Record (WPQR), not the PQR.

Question 4

Under AWS D1.1, a WPS must be qualified by test or may be prequalified. Which joint configuration is typically NOT eligible for prequalified status?

Accepted Answer

Partial joint penetration groove weld with electroslag welding

Answer

Electroslag and electrogas welding processes are specifically excluded from prequalified WPS status under AWS D1.1.

Question 5

Under ASME Section IX, the A-Number in a WPS refers to the classification of:

Accepted Answer

Deposited weld metal chemical composition

Answer

A-Numbers classify the chemical composition of the deposited weld metal and are used to group similar weld metal compositions.
