1. The primary responsibility of a CWB Level 2 Welding Inspector is to:
A. Perform production welding
B. Design welded structures
C. Supervise all shop personnel
D. Interpret codes, verify procedures, and oversee inspection
activities
Answer: D
Rationale: Level 2 inspectors focus on code interpretation, procedure
verification, and oversight of inspection processes rather than hands-on
welding or design.
, 2. Which CSA standard is most commonly applied to structural steel
welding in Canada?
A. CSA Z662
B. CSA W47.1
C. CSA W59
D. AWS D1.1
Answer: C
Rationale: CSA W59 governs welding of carbon steel and low-alloy steel
structures in Canada.
3. CSA W47.1 primarily addresses:
A. Welder performance qualification
B. Inspection techniques
C. Certification of companies for fusion welding of steel
D. Nondestructive examination requirements
Answer: C
Rationale: W47.1 defines company certification requirements, including
welding procedures and personnel.
, 4. A Welding Procedure Specification (WPS) is best described as:
A. A test record of completed welds
B. A visual inspection checklist
C. A welder qualification card
D. A written document providing direction for making production
welds
Answer: D
Rationale: A WPS gives essential and supplementary variables needed to
produce acceptable welds.
5. A Procedure Qualification Record (PQR) documents:
A. Visual inspection results
B. Welder training hours
C. Actual test data used to support a WPS
D. Base metal purchase information
Answer: C
Rationale: The PQR records variables and test results proving that the
procedure meets code requirements.
, 6. Which variable change normally requires requalification of a WPS?
A. Travel speed
B. Joint cleaning method
C. Change in welding process
D. Brand of electrode
Answer: C
Rationale: A change in welding process is an essential variable and
requires requalification.
7. In visual inspection, undercut is defined as:
A. Excess weld metal beyond the toe
B. Lack of penetration at the root
C. A groove melted into the base metal adjacent to the weld toe
D. Porosity visible on the surface
Answer: C
Rationale: Undercut reduces base metal thickness and can act as a stress
concentrator.
8. The most common cause of porosity in welds is:
A. Excessive heat input
