1. CSA W59 primarily governs welding requirements for which
materials?
A. Aluminum only
B. Stainless steel only
C. Structural steel and aluminum
D. Cast iron
Correct Answer: C
CSA W59 covers welding of structural steel and aluminum in Canada.
2. The primary responsibility of a Welding Inspector Level 1 is to:
A. Approve welding procedures
B. Perform production welding
C. Verify compliance with applicable codes
D. Design welded connections
Correct Answer: C
Level 1 inspectors focus on inspection and verification, not design or
procedure approval.
3. Which document specifies acceptable welding variables such as
current, voltage, and travel speed?
, A. WPS
B. PQR
C. WPQ
D. NDE report
Correct Answer: A
A Welding Procedure Specification (WPS) provides required welding
variables.
4. A Procedure Qualification Record (PQR) is used to:
A. Instruct welders
B. Record test results supporting a WPS
C. Qualify inspectors
D. Document repairs
Correct Answer: B
The PQR demonstrates that the WPS produces acceptable welds.
5. Which welding process uses a continuously fed consumable wire
electrode?
A. SMAW
B. GTAW
C. GMAW
D. SAW with strip electrode
Correct Answer: C
GMAW uses a continuously fed wire electrode.
6. Preheat is primarily applied to:
A. Improve weld appearance
B. Reduce hydrogen cracking
, C. Increase travel speed
D. Reduce spatter
Correct Answer: B
Preheating slows cooling and reduces the risk of hydrogen-induced
cracking.
7. The Heat Affected Zone (HAZ) is:
A. The weld metal only
B. The base metal unaffected by welding
C. The area of base metal altered by welding heat
D. The reinforcement area
Correct Answer: C
The HAZ experiences metallurgical changes due to welding heat.
8. Undercut is defined as:
A. Excess weld metal on the surface
B. A groove melted into the base metal adjacent to the weld
C. Cracks in the weld root
D. Incomplete penetration
Correct Answer: B
Undercut reduces cross-sectional thickness and may weaken the joint.
9. Which defect is most likely caused by excessive welding current?
A. Lack of fusion
B. Porosity
C. Undercut
D. Slag inclusion
Correct Answer: C
High current increases arc force, often leading to undercut.
