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?
Answer: Essential variable
A change in P-Number is an essential variable under ASME Section IX, requiring requalification of the WPS.
In ASME Section IX, filler metals are grouped into F-Numbers primarily to reduce the number of:
Answer: PQRs required for similar materials
F-Numbers group filler metals with similar usability characteristics so that qualification with one filler qualifies others in the same F-Number group.
Which of the following is NOT recorded on a Procedure Qualification Record (PQR)?
Answer: Welder's name and identification
The PQR records the actual welding conditions used; the welder's identity is tracked on a Welder Performance Qualification Record (WPQR), not the PQR.
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?
Answer: Partial joint penetration groove weld with electroslag welding
Electroslag and electrogas welding processes are specifically excluded from prequalified WPS status under AWS D1.1.
Under ASME Section IX, the A-Number in a WPS refers to the classification of:
Answer: Deposited weld metal chemical composition
A-Numbers classify the chemical composition of the deposited weld metal and are used to group similar weld metal compositions.
When a WPS lists a range of heat input, what is the inspector's responsibility during production welding?
Answer: Calculate heat input from voltage, amperage, and travel speed and verify it falls within the WPS range
The CWI must verify that the calculated heat input (volts × amps × 60 / travel speed in in/min) stays within the range established in the WPS.
Under ASME Section IX QW-451, a groove weld PQR performed on base metal 1 inch thick qualifies a WPS for production welds up to what maximum thickness?
Answer: 2 inches
Per QW-451, a test coupon of 1 inch thickness qualifies production welds up to 2 inches (2T), capped at certain limits.
