SECTION 1: CWB CERTIFICATION SYSTEM & INSPECTOR ROLES (CSA W178.2)
**Question 1**
What is the primary scope limitation of a CWB Level 1 Welding Inspector under CSA W178.2?
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 independently conduct inspections but must work under direct certified Level 2 or
3 supervision
D) They may approve welding procedures but cannot certify welders
**Correct Answer: C**
**Rationale:** Under CSA W178.2, Level 1 inspectors are considered entry-level. They may
independently conduct inspections but must work under the direct supervision of a certified
Level 2 or Level 3 welding inspector. Level 1 inspectors are not authorized to interpret non-
destructive testing (NDT) results beyond visual inspection, nor do they have the authority to
approve welding procedures or certify welders—these functions are reserved for higher-level
inspectors.

**Question 2**
Under CSA W178.2, what is the minimum visual acuity requirement for a Level 1 welding
inspector?
A) 20/20 vision in at least one eye, with or without correction
B) 20/30 vision in both eyes, with or without correction
C) 20/40 vision in at least one eye, with or without correction
,Page 3 of 162
D) 20/25 vision in both eyes, uncorrected
**Correct Answer: A**
**Rationale:** CSA W178.2 requires that welding inspectors have a minimum visual acuity of
20/20 (Snellen) in at least one eye, with or without correction. This ensures the inspector can
adequately detect and evaluate weld discontinuities during visual inspection. The visual acuity
must be verified using CWB Form 455.
---
**Question 3**
A CWB Level 1 Welding Inspector candidate must complete all certification examinations within
what timeframe from the application approval date?
A) 6 months
B) 1 year
C) 2 years
D) 3 years
**Correct Answer: C**
**Rationale:** All certification examinations must be completed within 2 years of the
application approval date. This time limit ensures that candidates maintain current knowledge
and skills throughout the certification process. Failure to complete all required examinations
within this period will require reapplication.

**Question 4**
Which form must be completed and submitted to verify visual acuity for CWB Level 1 Inspector
certification?
A) CWB Form 301
B) CWB Form 450
C) CWB Form 455
D) CWB Form 600
**Correct Answer: C**
**Rationale:** CWB Form 455 is the Visual Acuity Form that must be completed, submitted,
and approved prior to the course start date for welding inspector certification. Form 301 is the
Welding Inspector Application Guide, and Form 450 is the Welding Inspector Application Form.

**Question 5**
What is the passing grade required for CWB Level 1 course examinations?
A) 60%
B) 65%
C) 70%
D) 75%
**Correct Answer: C**
