CWI WPS and PQR Qualification Questions and Answers

Question 1

A Procedure Qualification Record (PQR) was created for a groove weld on 1-inch thick carbon steel plate using the Shielded Metal Arc Welding (SMAW) process.
All destructive tests were acceptable.
What is the primary purpose of this PQR?

Accepted Answer

To serve as the documented record of the welding variables used to produce an acceptable test weldment.

Answer

To provide the welder with instructions for making production welds.

Answer

To verify the skill of the welder who welded the test coupon.

Answer

To list the acceptable range of parameters for all future production welds.

Question 2

A fabricator has a qualified WPS for welding P-No. 1 to P-No. 1 base materials. A new project requires welding a P-No. 1 material to a P-No. 4 material. According to ASME Section IX, what action is required?

Accepted Answer

A new PQR must be completed to qualify a new or revised WPS.

Answer

No action is required; the existing WPS is sufficient.

Answer

A new Welder Performance Qualification (WPQ) must be performed.

Answer

The existing WPS must be revised by a welding engineer.

Question 3

When developing a Welding Procedure Specification (WPS) supported by a PQR, which of the following is true?

Accepted Answer

Several WPSs with different non-essential variables can be written from a single PQR.

Answer

The ranges listed on the WPS must be identical to the exact values recorded on the PQR.

Answer

The WPS can be written before the PQR is successfully completed.

Answer

The PQR lists the allowable ranges, while the WPS lists the actual values from the test.

Question 4

A welder is performing production welding using a qualified WPS. The WPS specifies a maximum interpass temperature of 450°F. The inspector measures the temperature between passes and finds it to be 500°F. What is the correct course of action?

Accepted Answer

Stop the work until the base material cools to below the specified maximum interpass temperature.

Answer

Allow welding to continue as the temperature is only slightly above the maximum.

Answer

Require the welder to requalify their performance qualification.

Answer

Revise the WPS on the spot to allow for the higher temperature.

Question 5

Which of the following changes would be considered a supplementary essential variable under ASME Section IX, requiring WPS requalification ONLY when notch-toughness tests are required?

Accepted Answer

A significant increase in heat input.

Answer

A change in welding position from 1G to 2G.

Answer

A change in the F-Number of the filler metal.

Answer

A change from stringer bead to weave bead technique.

Question 6

A PQR was qualified using the Gas Metal Arc Welding (GMAW) process with a shielding gas of 75% Argon / 25% CO2. The resulting WPS is to be used for a production weld. Which of the following shielding gases would require a new PQR?

Accepted Answer

100% CO2.

Answer

80% Argon / 20% CO2.

Answer

70% Argon / 30% CO2.

Answer

A different brand of 75% Argon / 25% CO2.
