personnel.
Question 2
According to CSA W178.2, a Level 3 Welding Inspector is considered:
A. An entry-level inspector requiring direct supervision
B. Fully competent to inspect without supervision
C. Capable of additional tasks such as inspections and test plan reviews
D. Limited to visual inspection only
Answer: C
Rationale: Level 3 welding inspectors have demonstrated additional technical
knowledge and are deemed capable of additional tasks such as inspections and test

A. 2 years of experience as a certified Level 2 inspector
B. 3 years of experience as a certified Level 2 inspector
C. 4 years of experience as a certified Level 2 inspector
D. 5 years of experience as a certified Level 2 inspector
Answer: C
pg. 3
, Rationale: For certification as a Level 3 welding inspector, candidates must have
at least four years of experience as a certified Level 2 welding inspector. The
experience ladder is specific: Level 1 → Level 2 (2 years), Level 2 → Level 3 (4
years).
Question 4
Under CSA W178.2, which of the following duties is exclusively reserved for a
Level 3 Welding Inspector?
A. Performing visual inspection of completed fillet welds
B. Setting up magnetic particle inspection equipment
C. Preparing and signing the final inspection report and supervising Level 1 and 2
personnel
D. Conducting hardness testing
Answer: C
Rationale: Level 3 inspectors carry program responsibility: procedure review, and
verifying that NDE and other examinations were done to the specified degree.
They are responsible for preparing and signing final inspection reports and
supervising Level 1 and 2 personnel.
Question 5
A Level 3 Welding Inspector is reviewing a quality manual. According to CSA
W47.1 Clause 5.1, which element must be included?
A. A copy of every employee's welding ticket
B. An organization chart showing inspector authority independent of production
C. A list of all suppliers
D. A copy of the company's financial statements
Answer: B
Rationale: CSA W47.1 Clause 5.1 requires the Quality Assurance Manual to
include an organization chart showing inspector authority independent of
production. This ensures inspection personnel are not influenced by production
pressures.
