Your CWB Level 1 Certification on the First Attempt
Section 1: CWB Certification System & Role Responsibilities
Q1. 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 – Rationale:- CWB Level 1 inspectors are certified for visual
inspection only. Interpreting NDT results requires Level 2 certification.
Q2. Under the CWB W178.2 standard, 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 – Rationale:- W178.2 requires 20/20 vision (with or without
correction), verified annually.
Q3. A CWB Level 1 inspector observes a welder using a WPS that has
expired. What is the inspector's correct course of action?
A) Immediately stop the work and issue a stop-work order independently
B) Document the observation and immediately notify the responsible engineer
or supervisor
,C) Allow the work to continue while the inspector researches the correct WPS
D) Inform the welder privately and suggest they switch to a valid WPS without
documentation
Correct Answer: B – Rationale:- Level 1 inspectors report non-conformances;
they do not have independent stop-work authority.
Q4. Which of the following welding discontinuities is a CWB Level 1 inspector
NOT qualified to evaluate?
A) Surface cracks detected by visual examination
B) Undercut measured with a weld gauge
C) Internal porosity identified through radiographic interpretation
D) Excessive weld reinforcement measured with a fillet weld gauge
Correct Answer: C – Rationale:- Internal porosity requires radiographic
interpretation (NDT beyond Level 1 scope).
Q5. What is the maximum validity period for a CWB Level 1 Welding
Inspector certification?
A) 1 year
B) 2 years
C) 3 years
D) 5 years
Correct Answer: C – Rationale:- CWB Level 1 certification is valid for 3 years,
then recertification is required.
Q6. A Level 1 inspector discovers that a colleague has been falsifying
inspection records. What is the inspector’s ethical obligation?
A) Confront the colleague privately and give them a chance to correct the records
B) Report the falsification to the employer and/or CWB immediately
C) Document the concern but wait for management to discover it independently
D) Ignore it if the falsified records do not affect structural safety
Correct Answer: B – Rationale:- Falsification must be reported immediately to
uphold professional integrity and safety.
,Q7. Which document establishes the competency requirements for CWB
welding inspectors in Canada?
A) CSA W59
B) CSA W47.1
C) CSA W178.2
D) CSA W186
Correct Answer: C – Rationale:- CSA W178.2 specifically addresses welding
inspector certification.
Q8. What is the minimum education requirement for an individual seeking
CWB Level 1 Welding Inspector certification?
A) High school diploma or equivalent
B) College diploma in welding technology
C) University engineering degree
D) No formal education requirement exists
Correct Answer: A – Rationale:- High school diploma or equivalent is the
minimum education requirement.
Q9. A Level 1 inspector is asked to sign off on welds they did not personally
witness. What should the inspector do?
A) Sign off if they trust the welder's reputation
B) Refuse to sign and report the request to their supervisor
C) Sign off but make a note that they did not witness the welding
D) Ask a colleague to witness the welds retroactively
Correct Answer: B – Rationale:- Signing unwitnessed work is fraudulent;
inspector must refuse and report.
Q10. Which of the following is NOT a responsibility of a CWB Level 1
Welding Inspector?
A) Verifying welder qualifications are current
B) Measuring weld dimensions against WPS requirements
C) Developing welding procedures for new applications
D) Checking preheat temperature before welding begins
, Correct Answer: C – Rationale:- Developing WPS requires engineering
judgment beyond Level 1 scope.
Q11. When must a CWB Level 1 inspector recertify their visual acuity?
A) Only when they notice vision problems
B) Every 6 months
C) Annually
D) Only at initial certification
Correct Answer: C – Rationale:- Annual visual acuity verification is mandatory
per W178.2.
Q12. What is the correct action if a Level 1 inspector identifies a safety hazard
unrelated to welding quality?
A) Ignore it and focus only on welding inspection duties
B) Report it to site safety personnel or management immediately
C) Document it but wait for the safety inspector’s scheduled visit
D) Only report it if it directly affects weld quality
Correct Answer: B – Rationale:- Safety hazards must be reported immediately,
regardless of weld quality.
Q13. Which organization issues CWB welding inspector certifications in
Canada?
A) American Welding Society (AWS)
B) Canadian Welding Bureau (CWB)
C) International Institute of Welding (IIW)
D) Canadian Standards Association (CSA)
Correct Answer: B – Rationale:- CWB is the certifying body for welding
inspectors in Canada.
Q14. A CWB Level 1 inspector must recertify every 3 years. What is one
recertification requirement?
A) Pass a practical welding test
B) Submit proof of continued visual acuity and activity log
