Sample Questions
Try a few questions to see what the full exam is like.
At a Part B acceptance station, the exhibit identifies the application as performance qualification groove. The measured condition is: a single pore measures 2.4 mm. What is the correct disposition?
At the end of a Part B station, you must choose the best inspection record/disposition. The situation is that a bend specimen has transverse grinding marks called out by the question. Which record is most defensible?
In a timed Part B station, the supplied temperature indicator from the exhibit is selected for minimum preheat before completing a pressure-piping weld. Which use of the tool gives the defensible inspection result?
During the Part B document review, compare the WPS/PQR exhibit with the inspected weld. WPS references two PQRs; only one supports the filler metal classification used. What should the inspector conclude?
During Part B visual inspection of groove replica G-6, the examiner asks you to classify the primary indication before making an acceptance decision. You observe cover pass reinforcement is smooth but transitions abruptly at one toe. Which finding should be recorded first?
