Practice Questions with Correct Answers COVERING MOST TESTED
QUESTIONS
The CWB Level 1 Welding Inspector – Basic Welding Inspection exam evaluates
foundational knowledge required for entry-level welding inspectors in Canada.
It focuses on visual inspection methods, weld symbols, welding defects, and
relevant codes such as CSA W59 and W47.1. This certification is essential for
individuals pursuing careers in welding quality control and compliance.
When sampling is left to the inspector, the number of samples selected should:
A) not be excessive but should be sufficiently random to determine that the required standards are
being met.
B) not be enough to cause production delays in the project.
C) be in areas that are easily accessible for the type of test requested.
D) be easy to control during the testing. - CORRECT ANSWER-A
A discontinuity is defined as:
A) any disruption in the physical or compositional feature of a part.
B) a disruption that exceeds the acceptance criteria of the relevant code, standard, or specification.
C) a flaw in the base metal that lies parallel to the surface.
D) a defined set of parameters against which the features of a component may be judged. -
CORRECT ANSWER-A
