CWI WPS and PQR Qualification 3

Question 1

How many guided bend specimens are required for procedure qualification of a groove weld under ASME Section IX when the test plate is less than 3/8 inch thick?

Accepted Answer

1 face bend and 1 root bend

Answer

For base metal less than 3/8 inch thick, ASME Section IX requires one face bend and one root bend test specimen.

Question 2

During a guided bend test for procedure qualification, a specimen fails if it shows a crack or open defect exceeding:

Accepted Answer

1/8 inch in any direction

Answer

Per ASME Section IX QW-163, a guided bend specimen fails if any crack or open defect exceeds 1/8 inch measured in any direction after bending.

Question 3

A reduced-section tension test specimen taken from a procedure qualification test coupon must fracture:

Accepted Answer

At or above the minimum specified UTS of the base metal

Answer

The reduced-section tension test must demonstrate tensile strength equal to or greater than the minimum specified UTS of the base metal, regardless of fracture location.

Question 4

Which test is NOT routinely required for standard groove weld procedure qualification under ASME Section IX?

Accepted Answer

Hardness test

Answer

Hardness testing is only required for certain P-Numbers and when specifically required by the referencing code; it is not a standard routine test for all groove weld PQRs.

Question 5

Under AWS D1.1, a groove weld procedure qualification test plate must be subjected to what type of nondestructive examination before mechanical testing?

Accepted Answer

Radiographic or ultrasonic testing

Answer

AWS D1.1 requires radiographic or ultrasonic testing of the procedure qualification test plate prior to cutting mechanical test specimens.
