AWS Certified Welding Inspector Exam
WPS/PQR Requirements Practice Questions
8 practice questions with detailed explanations — aligned to the AWS Certified Welding Inspector Exam.
Q1.Which of the following is NOT an essential variable for a WPS?
A.Change in filler metal classificationB.Change in shielding gasC.Change in welder's nameD.Change in preheat temperatureC. Change in welder's nameExplanation: The welder's name is administrative. Essential variables (filler, gas, preheat) affect the mechanical properties of the weld.

Q2.A decrease in the preheat temperature below the minimum specified in the WPS:
A.Is permittedB.Requires requalificationC.Is acceptable if the ambient temp is highD.Requires only a revisionB. Requires requalificationExplanation: Decreasing preheat increases the cooling rate, potentially causing cracking or hardness issues. It is an essential variable requiring requalification.

Q3.The PQR must record:
A.The range of variables allowedB.The actual values of variables used during the test weldC.The welder's SSND.The project nameB. The actual values of variables used during the test weldExplanation: The PQR is a record of *actual* conditions. The WPS defines the *ranges* allowed based on that PQR.

Q4.Which test is NOT required for a groove weld PQR on plate?
A.Visual InspectionB.Reduced Section TensionC.Guided Bend TestsD.Radiography (RT)D. Radiography (RT)Explanation: Standard D1.1 groove weld PQRs require Visual, Tension, and Bend tests. RT is used for *welder* qualification (optionally) but is not a standard requirement for *procedure* qualification unless NDT is substituted for bends (rare in initial PQR). Wait, standard PQR is mechanical testing. RT is NDT.

Q5.If a WPS is qualified in the 2G position, it qualifies for:
A.All positionsB.2G position only (plus flat)C.Vertical positionD.Overhead positionB. 2G position only (plus flat)Explanation: Procedure qualification in 2G qualifies for 1G (Flat) and 2G (Horizontal). It does NOT qualify for Vertical or Overhead. (Note: This differs from *Welder* qual where 3G/4G are key. Procedure qual positions are non-transferable to 'harder' positions without testing). *Correction:* D1.1 Table 4.1: Plate test in 2G qualifies for 1G and 2G. Qualification in *all* positions usually requires 1G+3G+4G tests, or a pipe 6G test.

Q6.For CVN (Charpy) testing in a PQR, the location of the notch must be:
A.In the weld metalB.In the HAZC.In the base metalD.In the weld metal, HAZ, and/or fusion line as specifiedE.AnywhereD. In the weld metal, HAZ, and/or fusion line as specifiedExplanation: Toughness requirements usually specify notches in the Weld Metal Centerline AND the HAZ (and sometimes Fusion Line + 1mm, etc.) to ensure all zones meet the criteria.

Q7.Changing the current from AC to DC:
A.Requires requalificationB.Is a non-essential variableC.Is permitted without testingD.Only matters for GTAWA. Requires requalificationExplanation: Current type and polarity are essential variables. Changing AC to DC changes penetration and heat input significantly.

Q8.WPSs for Electroslag Welding (ESW) must always be:
A.PrequalifiedB.Qualified by testingC.Written by an engineerD.Used for thin platesB. Qualified by testingExplanation: ESW (and EGW) are NEVER prequalified processes in AWS D1.1. They always require qualification testing.
