CWB LEVEL 1 EXAM PREP 2026/2027 — 350
PRACTICE QUESTIONS AND CORRECT ANSWERS
AND WELL DETAILED EXPLANATIONS
SECTION 1: CWB CERTIFICATION SYSTEM & INSPECTOR ROLES (Questions 1–35)
1. What is the primary scope limitation of a CWB Level 1 Welding Inspector?
A) They may perform ultrasonic testing but cannot interpret results
B) They are restricted to visual inspection only and may not interpret NDT results
C) They may perform magnetic particle testing and interpret findings
D) They are authorized to approve welding procedures and WPS documents
Correct Answer: B — CWB Level 1 inspectors are certified for visual inspection
only; interpreting NDT results requires Level 2 certification.
2. Under CSA W178.2, what is the minimum visual acuity requirement for a Level
1 Welding Inspector?
A) 20/40 vision, corrected or uncorrected
B) 20/30 vision, corrected or uncorrected
C) 20/20 vision, corrected or uncorrected
D) 20/25 vision, corrected or uncorrected
,Correct Answer: C — CSA W178.2 requires 20/20 vision (with or without
correction) for welding inspectors, verified annually.
3. When a CWB Level 1 inspector observes a welder using a WPS that has expired,
the inspector should:
A) Immediately stop the work and issue a stopwork order independently
B) Document the observation and immediately notify the responsible engineer or
supervisor
C) Ignore the issue because the inspector's role is limited to visual inspection
D) Personally requalify the WPS on the spot
Correct Answer: B — The inspector reports nonconformances; stopping work and
requalifying are responsibilities of higher authority.
4. All reports produced by an inspector should be:
A) Neat, accurate, complete, and timely
B) Technical, complete, accurate, and include pictures
C) Completed as soon as fabrication has finished
D) Delivered to the end user upon completion
Correct Answer: A — Inspector reports must be professional, factual, complete,
and submitted in a timely manner for effective quality control.
5. Under CSA W178.2, Level 1 welding inspectors must work:
A) Completely independently without any supervision
B) Under direct certified Level 2 or 3 supervision
,C) Only under the direct supervision of a Professional Engineer
D) Without any oversight once certified
Correct Answer: B — Level 1 is entrylevel; inspectors work under certified Level 2
or 3 supervision.
6. What does the acronym WPS stand for?
A) Welding Procedure Specification
B) Welding Procedure Standard
C) Welding Process Specification
D) Welding Parameter Sheet
Correct Answer: A — WPS is the document that provides the required welding
variables for a specific application.
7. In a nonconformance program, what colour is used to indicate a product hold?
A) Yellow
B) Red
C) Green
D) Blue
Correct Answer: A — Yellow is used to indicate a product hold in a
nonconformance program.
8. What is the main advantage of welding inspection?
, A) The ability to call for specific types of quality testing when needed
B) The ability to communicate between shop and engineering staff
C) The ability to capture and resolve quality nonconformances
D) The ability to catch problems before they impact quality and delivery
Correct Answer: D — Inspection catches problems early, preventing quality and
delivery impacts.
9. What three key items form the "Quality Triangle for Welding" and are required
prior to fabrication?
A) Proper functioning welding machine, approved welding procedures, and
qualified welders
B) Approved welding procedures, qualified welders, and correct materials
C) Correct material, approved drawings, and skilled welders
D) Approved procedures, process verification, and detailed inspection test plan
(ITP)
Correct Answer: B — The quality triangle consists of approved procedures,
qualified welders, and correct materials.
10. Once inspections have been finished, who completes the final reports?
A) The QA manager
B) The fabricator
C) The governing body
D) The inspector
