CWS Weld Procedure Specifications & Qualification 3

Question 1

What information is typically NOT required on a Weld Procedure Specification?

Accepted Answer

Welder's personal Social Security number

Answer

A WPS documents technical welding parameters and material specifications, not personal identification information about individual welders.

Question 2

A Certified Welding Supervisor reviews a WPS and notices the heat input for a high-strength steel exceeds the qualified range. The correct action is to:

Accepted Answer

Require requalification of the procedure at the higher heat input

Answer

Exceeding the qualified heat input range is an essential variable change that requires procedure requalification to ensure the weld properties remain acceptable.

Question 3

Under ASME Section IX, an F-Number is used to classify:

Accepted Answer

Filler metals into groupings for welder qualification

Answer

F-Numbers classify filler metals into groups based on usability characteristics, allowing one welder qualification to cover multiple filler metals within the same F-Number group.

Question 4

Which of the following is a supplementary essential variable that becomes essential when Charpy V-notch impact testing is required?

Accepted Answer

Transfer mode (spray vs. short-circuit)

Answer

Transfer mode is a supplementary essential variable; when notch toughness testing is required, changing the transfer mode requires requalification.

Question 5

When a welding supervisor audits the qualification records, which documents should be cross-checked together to verify a welder is qualified?

Accepted Answer

Welder Performance Qualification Record and the applicable WPS

Answer

The welder's performance qualification record must be cross-checked against the applicable WPS to confirm the welder is qualified for the variables required by that procedure.
